6.1 How to Use This Section<br />

The following section is structured in a manner such that the medical air system for a project may be established and<br />

executed in a sound and simple progression. Examples are given whenever possible.<br />

The basic milestones in designing the medical air system are as follows:<br />

• Definitions – Definitions are provided in the glossary section which contains terminologies which may be<br />

frequently utilized within the Medical <strong>Air</strong> <strong>System</strong>s section. These terms may also be helpful in understanding<br />

and specifying the appropriate medical air system.<br />

• Design – General outline pertaining to the procedural involvement in designing your Medical <strong>Air</strong> <strong>System</strong>s.<br />

• Sizing and Selecting the Medical <strong>Air</strong> <strong>System</strong> – Step by step calculation exemplifying how to calculate the<br />

Peak Calculated Load (PCL) Requirements for the medical facility.<br />

• Installation – Steps to building your medical air systems.<br />

6.2 Introduction<br />

Medical <strong>Air</strong> <strong>System</strong>s<br />

The NFPA-99 standards for Medical <strong>Air</strong> <strong>Compressor</strong>s define an essential foundation of Medical <strong>Air</strong> <strong>Compressor</strong>s<br />

as follows: <strong>Air</strong> should start clean and be kept clean. For that reason, the air inhaled by the patient at the very least<br />

should be minimally equal to filtered local outdoor air.<br />

All compressors included herein are deemed suitable for medical use under The NFPA Standards. For further<br />

information on NFPA compliant medical systems, please consult your Local <strong>Amico</strong> Source representative.<br />

6.2.1 The Four Essentials To Building A Medical <strong>Air</strong> <strong>System</strong>:<br />

1. The intake air location must never be contaminated by placing the medical air systems in a poorly<br />

ventilated area.<br />

2. The medical air must be available at all times, including in the event of a single fault failure.<br />

3. The air must be dry enough to ensure no liquid water can develop under any normal operating conditions<br />

(This is not necessarily assured simply by meeting the NFPA mandated dew point).<br />

4. Any contamination whereby the system can produce within itself under any conditions (e.g. particulate)<br />

must be removed (e.g. by filtration) before it can reach the patient.<br />

NFPA defines various rules for the construction of the air plant and the safety devices required for each machine<br />

type. Additionally, good engineering practice defines crucial elements such as after coolers, drains and traps,<br />

dryers, vibration isolation, and hundreds of other small but significant elements of good air system design. <strong>Amico</strong><br />

Source has pre-engineered all the medical air systems in this section to warrant that they include not only the basic<br />

requirements of the principles, but also the many foundations behind good engineering. This section of the design<br />

guide also permits the user to make selections of complete medical air packages for reasons specified hereafter. It<br />

is impractical to craft a design guide encompassing all the knowledge <strong>Amico</strong> Source’s engineers have applied to<br />

the design of these systems. Nevertheless, within this design guide, you can easily locate the necessary information<br />

to ensure you can apply these systems with confidence and provide for your client a fully satisfactory medical air<br />

system. Medical <strong>Air</strong> in smaller systems may be provided by manifolds in lieu of compressor systems. The sizing<br />

criteria are the same for either source type.<br />

6.3 Steps to Implementing the Medical <strong>Air</strong> <strong>System</strong>s<br />

6.3.1 Discovery<br />

1. Should existing equipment be incorporated along with the medical air system, determine the<br />

dimensions, type, capacity and current loading of the existing equipment. Ensure the existing equipment is<br />

compatible with the current standard.<br />

2. Verify the number and type of all occupancies in the facility which will require medical air outlets.<br />

3. Determine the number of ventilators required to be in service at any one time and define their type and<br />

average inlet air requirement.<br />

4. The intake piping for a medical air compressor system should only be connected to the medical air<br />

compressor system and not used for any other purpose. It should be made of hard-drawn seamless copper,<br />

either ASTM B 819 medical gas tube, ASTM B 88 water tube (Type K, L, or M), or ASTM B 280 ACR tube, which<br />

ensures no contaminants in the form of particulate matter, odor or other gases will be added. This piping is<br />

to be labeled and equipped with intake filters that are located inside the health care facility, close to the<br />

compressor, and are easily accessible for servicing. Examine the location intended for the air intake carefully<br />

as NFPA mandates the intake be located at a minimum of 10 ft. (3 m) from any door or operable window;<br />

20 ft. (6.1 m) above grade, and in a location likely to provide uncontaminated air under any conditions of<br />

wind or weather. The intake opening shall be turned downward and screened. It shall be accessible<br />

to authorized personnel for cleaning, inspection and servicing. If the air intake is near a loading dock or at a<br />

location where vehicles may be present, it must be relocated. It is advisable to place the intake at<br />

a height above any other intake or vent on the same roof (See Figure 1 below). For further details regarding<br />

the rules and regulation in choosing your medical air system location, please refer to the latest edition of the<br />

NFPA specification guide.<br />

Figure 1:<br />

<strong>Amico</strong> Source Equipment


5. Determine a routing for the intake piping and note it on the building drawings. Piping downstream of the<br />

compressor shall be routed in a manner such that it is not subjected to temperatures lower than 40 o F (4 o C).<br />

6. Ensure the intended location for the air plant is adequately ventilated or is at minimum air conditioned. The<br />

plant will emancipate a considerable amount of heat into the surroundings. Hence, it must be factored<br />

in when selecting a compressor site; determining the adequacy of ventilation; or identifying BTU<br />

requirements for air conditioning. (BTU data is furnished in the equipment data sheet).<br />

7. Determine the availability of electrical service.<br />

8. If the medical air system is not already piped to the proposed location, determine the routing for<br />

the piping and note it on the building drawings.<br />

6.3.2 Design<br />

1. Follow directions for laying out piped medical gases. This will supply a count of outlets which is<br />

necessary for the next steps.<br />

6.3.3 Plant Sizing<br />

There are several available methods for sizing Medical <strong>Air</strong>. For the purpose of this design guide, only the National Fire<br />

Protection Association (NFPA) Method will be discussed.<br />

The NFPA Plant Sizing Method<br />

1. Count all outlets within the infrastructure that will utilize the air compressor system (See Figure 2).<br />

In situations in which the exact type of room cannot be located within the table, please select the<br />

one which most closely approximates the room as indicated in the chart.<br />

2. Once the total amount of outlets are entered, the next step entails multiplying all variables across the table<br />

(left —>right) to apply the simultaneous usage factor.<br />

3. Obtain an estimate of air requirement by summing the columns (top v |<br />

bottom).<br />

4. NFPA recommends the inclusion of additional capacity for potential ventilator use. However, this ventilator<br />

factor causes significant problems and is usually the cause behind gross over-sizing for medical air<br />

plants. Therefore, extreme caution should be taken.<br />

PEAK CALCULATED DEMAND IN SCFM<br />

BASED ON FREE AIR SCFM @ 50PSI:<br />

1. The SCFM above is based on a peak OUTLET demand of 50 psi. <strong>Air</strong> compressors operate at 100 psi. When<br />

sizing a compressor, you MUST figure the compressor capacity for operation at 100 psi.<br />

2. You need to consider several environmental factors when sizing the compressors. These include altitude,<br />

intake air temperature, and relative humidity. Variance among these factors has considerable effect on<br />

compressor selection.<br />

3. <strong>Air</strong> outlets in labs used for analysis, research or teaching should be supplied by a separate compressed air<br />

system, not the medical air system.<br />

4. All sizing methods are only approximations and should be used judiciously. If an existing compressor is<br />

being replaced, the operating characteristics of that compressor can be an important gauge of likely future<br />

use. For example, if an existing 5 HP compressor provides an ample amount of medical air, but the<br />

sizing tables yield much larger requirements; it may be suitable to use a smaller compromise unit as<br />

opposed to simply relying on the results from the <strong>Amico</strong> Sizing Guide.<br />

6.3.4 Altitude Adjustments<br />

If the compressor is to be operated at higher elevations, the peak calculated demand should be multiplied by the<br />

corresponding correction factor. Specifically, at altitudes above sea level, all medical air systems have reduced flow.<br />

In such cases, the required sizing will need to be adjusted by taking the total PCL (SCFM) and multiplying it by the<br />

correction factor (See Figure 3 below).<br />

6.3.5 “Future expansion” Compensation<br />

The notion of adding capacity now for any future requirements is wise, but extreme caution IS also advised. It<br />

is common to see very badly oversized air plants which were initially sized to accommodate an expansion that<br />

never occurred or that was scaled back and was not compulsory after all. In addition to the waste of investment, it<br />

generates problems associated with the operation of the system. The best method in preparing for an anticipated<br />

expansion is to opt for a plant which is adequate for the present need in a duplex or triplex system but can also<br />

be upsized for future need by simply adding additional compressors as required. When specifying for the unit,<br />

require it be purchased in preparation for additional compressor(s) yet not populated with those compressors. A<br />

representative specification would read: “provide duplex medical air plant with triplex controls and air treatment<br />

subsystem ready for a future third compressor”. Such a system provides an effective method of expanding the system<br />

capacity, is more capital-efficient, and yields better operating characteristics and reliability when it comes to air<br />

quality control. Nevertheless, it is fundamentally important that the intake, electrical service, and system piping are<br />

correctly sized for the entire expected capacity, so these larger values should be used in all calculations.<br />

6.3.6 Plant Selection<br />

1. Select a preferred technology (See Sec 6.3.9). More specific assistance in selecting a technology may be<br />

obtained by contacting your Local <strong>Amico</strong> Source representative.<br />

2. Choose a Horsepower from the preferred technology with the capacity closest to (but typically greater than)<br />

the Peak Calculated Load (PCL).<br />

3. Note that for some technologies, there is more than one plant architecture. Should one or more layout be<br />

available for selection, choose the one best suited to the site conditions. If in doubt as to which arrangement<br />

is most suitable for a particular situation, contact your Local <strong>Amico</strong> Source representative for assistance.<br />

4. Reference the Technology Comparison Chart for the particular system selected. This sheet entails all the<br />

essential information regarding the system and should be utilized as a quick reference in all of the following<br />

steps.<br />

<strong>Amico</strong> Source Equipments


6.3.7 General Layout<br />

1. Place the plant in scale on the plan drawings in the designated location. Ensure that the plant has sufficient<br />

space on all sides for maintenance access and proper ventilation. <strong>Amico</strong> Source recommends 2 ft. (24”)<br />

minimum clearance on all sides, 3 ft (36”) in front of the control panel, but it is sometimes possible to reduce<br />

this clearance with exact knowledge of maintenance access requirements. Consult your Local <strong>Amico</strong> Source<br />

representative if circumstances allow for less space.<br />

2. Place the equipment in elevation views as appropriate.<br />

3. On the plan, finalize the routing for the intake.<br />

4. Size the intake piping. The sizing process is iterative:<br />

a. Start with the total actual length of piping, and make an estimate for the line size (See Figure 4).<br />

b. By using your estimated size, add equivalent lengths for the fittings employed.<br />

c. Check that the size of the intake piping is still suitable at the new equivalent length. Should there be<br />

any discrepancies, re-estimate the next larger size and repeat the steps above. The line may also be<br />

sized more precisely by conducting an actual calculation. Intake piping must be sized to induce no<br />

more than 4 inches water column vacuum at the compressor when all compressors are operating.<br />

(Use total capacity for this calculation with all compressors running).<br />

For unusual lengths or other circumstances, please contact your Local <strong>Amico</strong> Source representative<br />

for assistance.<br />

5. Finalize the connection to the distribution piping and size the system piping.<br />

6.3.8 Specification<br />

1. Select the sections appropriate to the technology and system layout desired.<br />

2. Note into the specification any exceptional requirements (soft starters, etc.) that are necessary.<br />

3. Schedule in the drawings the medical air plant selected.<br />

Schedule at least:<br />

a. The capacity per compressor (per NFPA) and total system capacity.<br />

b. Horsepower per compressor.<br />

c. Voltage, Hz, and phase desired.<br />

6.6 Medical <strong>Air</strong> <strong>System</strong> Inlet<br />

Below is a summary of the requirements for the medical air system inlet locations.<br />

1. Locate the medical air inlet in an area where there will not be potential hazards such as<br />

contamination from engine exhausts, fuel storage vents; toxins or hazardous contaminants, such as<br />

ethylene oxide (ETO) gas exhaust vents, medical vacuum exhaust vents, particulate matter or odor<br />

of any type.<br />

2. Locate the medical air inlet outdoors above the roof level a minimum distance of 10 ft. (3 m) from<br />

any door, window, exhaust, other intake or opening in the building, and a minimum distance of<br />

20 ft. (6.1 m) above the ground. Intakes shall be turned down and screened or otherwise be<br />

protected against the entry of vermin or water, with screening that is to be fabricated from or<br />

3. If a source is available that is equal to or superior to outside air (For example, air already filtered for<br />

use in the operating room ventilation systems), it shall be permitted to be used for the medical air<br />

compressors. This alternative source of supply air must be available on a continuous 24-hours-a-day,<br />

7-days-per-week basis. Ventilating systems having fans with motors or drive belts located in the air<br />

stream shall not be utilized as a source of medical air intake.<br />

4. Medical air intakes for separate compressors shall be permitted to be joined together to one<br />

common intake, provided such intake is appropriately sized.<br />

5. Figure 4 details the minimum inlet pipe sizing required based on the medical air system<br />

horsepower, configuration, and the total pipe length (including elbows) in the medical air intake<br />

line.<br />

a. The medical air intakes are joined together to one common intake.<br />

b. All pipe sizes are based on copper pipe Type L.<br />

c. Minimum pipe size must be preserved for the total length of inlet pipe.<br />

d. Use the next larger size pipe in the event the minimum size is not available.<br />

e. When determining the Total Pipe Length (TPL), add all straight lengths of pipe together plus<br />

the number of elbows multiplied by the effective pipe length for that pipe size.<br />

(See Figure 4).<br />

Figure 5: Example 1 Calculating SCFM<br />

After interviewing the hospital engineer, you find that the facility; which is located 2,000 feet above sea level, has 5<br />

minor Operating Rooms, 6 ICU Ventilators, 18 ICU Beds, and 12 Recovery beds. They also want to have a 25% future<br />

expansion. Calculate the total PCL for the facilities Medical <strong>Air</strong> system.<br />

Total Facility PCL Requirements (SCFM)<br />

1. Based on the typical ventilator requirements for “specific ventilator requirements”, check with<br />

ventilator manufacturer.<br />

2. If the number of ventilators in the hospital is unknown, allow one ventilator per bed for 75% of the<br />

available ICU/NICU beds.<br />

3. The ICU area has 18 beds and 6 ventilators. The flow required for the ventilators supersedes that of<br />

the ICU beds, so only 12 of the ICU beds are counted and added to the 6 ventilator requirements<br />

when determining total facility requirements.<br />
