In operation, the rotating impeller draws in air from the inletport into the compression space and moves it radially outward to thecurved housing by centrifugal force.The action is called “regenerative” because a certain amount of airslips past each impeller blade during rotation and returns to the baseof a succeeding blade for reacceleration.Because of this dynamic principle, regenerative blowers can generatepressure and vacuum performance comparable to many multi-stage orpositive displacement blowers.www.gastmfg.com Gast Regenair® Regenerative Blowers 3

Blower System Design TipsIn order to utilize your regenerative blower most efficiently,proper system design is essential. The most importantthing to recognize is that by utilizing large diameterplumbing, friction losses in plumbing can be greatlyreduced. Here are some guidelines to use when setting upyour blower system:1. The plumbing should at least be the same size as theblower port or ideally one size larger (example - blowerhas ports that are 1-1/2” NPT, plumbing should be 2”NPT). The plumbing should remain this size until it hasreached the location of the work area.2. Plumbing for Separate Drive Blowers operating above3500 RPM should be at least one pipe size larger thanthe blower ports.3. Elbows create additional friction which causes pressureloss and back pressure. Plumbing at least one pipesize larger than the blower pipe ports minimizes thefriction loss they create.4. The pressure/vacuum relief valve should be installedin a “T” which is at least one pipe size larger than thatof the exhaust of the blower. To properly protect alarge horsepower blower, set the relief value to limitthe blowers duty to 5 inH 2O below its continuous dutyrating.5. Operating the blowers at high altitude decreases theirmaximum pressure or vacuum duty rating. If this is aconsideration, review the information on Fan Laws inthe Application Engineering section of this catalog.6. The exhaust air temperature of the blowers increaseswith increasing duty. At duties over 70 inH 2O it istoo hot for most plastic pipe. Metal pipe must beconsidered. To prevent danger of burns, access tothese pipes should be limited, guarded, or marked“Danger Hot.”Performance DataThe performance data shown in this catalog wasdetermined under the following conditions:• Line voltage @ 60 Hz 230V or 460V for three-phaseunits. 115V or 230V for single-phase units.• Line voltage @ 50Hz 220V for three-phase or singlephaseunits.• Units in a temperature stable condition.• Delivery measurements made with output port throttled.• Suction measurements made with input port throttled.• Test Conditions: Inlet air density at 0.075 lbs per cu ft.[20 °C (68 °F), 29.92 inHg (14.7 PSIA)].• Normal performance variations on the resistance curvewithin ± 10% of supplied data can be expected.www.gastmfg.com Gast Regenair® Regenerative Blowers 5

Typical Applications – Imagine what you can do with air,We offer cost-effective solutions to blower applications for both OEMs and end-users. Gast’s Regenerative Blower line of products aredesigned and built to meet the changing needs of industry and are ideally suited for a number of blower applications. These are examplesof many applications where Gast’s Regenerative Blowers are widely used.Pressure ApplicationsBag Packaging EquipmentVacuum is often used to open,hold, and close bags in fillingmachines.Vacuum ConveyingPlastic pellets, grain, powder, andother bulk dry materials can betransported from one container toanother easily using vacuum. Theyare pulled into a transport tubeand delivered to a separator beforebeing deposited in the final storagecontainer.Pond AerationPond aeration is done for two basicreasons. One is aquaculture, wherelarge numbers of fish are “farmed”in a single pond. The second isecological. As a pond or lake ages,it can lose its oxygen supply andmay die. When air is introduced intoa pond or lake, oxygen becomesplentiful again and life in and aroundthe water can flourish.Paper Stack Air TableThe stacks of paper in all graphicarts applications are extremely heavy.To make matters more difficult, thecombination of high speed pressesand the various types of paper makeit necessary to handle these stacksfrequently. To make the job easier,these stacks are floated on an air tableso they can be manipulated with verylittle effort.Agricultural equipment• Aquaculture/pond aeration• Fish hatchery equipmentTransportation equipment• Suspension systems, tire inflatorsMedical equipment• Medical and dental sterilizing equipment• Dental hand tools, air mattressIndustrial tools and machinery• Fiberglass choppers• Liquid/hydraulic pump drives• Industrial cleaning equipment• Chip removal/parts blowoff• Engraving machineryMaterial handling equipment• Lift tables• Pneumatic conveying systems and drives• Automated assembly machines/roboticsComputer, business, office machines,and equipment• Envelope opening/inserting/labelingequipment• Document scanning equipmentGraphic arts equipment• Folders, presses, counters• Photo processing equipment• Corrugated cutting/printing equipment• Ink jet printer/post press printing equipment• Collating/inserting equipment• Ink drying equipment• Air tableSports and leisure equipment• Spa and hot tub aeration, aquarium aeration• Handicap tub door seals, boat/pond deicingFood, drug, and chemical equipment• Ice cream/yogurt/frosting dispensers• Pharmaceutical manufacturing equipment• Automated food preparation equipmentElectronics and communicationsequipment• Cable pressurization/cable slicing equipment• Circuit board processing equipmentEnvironment, pollution, and safety equipment• Air/water purifiers• Gas generators (ozone, nitrogen)• Sewage treatment• Smoke evacuation• Pest control equipment• Soil/groundwater remediation equipmentPackaging equipment• Marking/labeling equipment• Filling equipment• Food packaging/bag making equipment• Can/bottle making equipment• Liquid packaging equipment• Corrugated sheet making equipmentTextile industry equipment• Sewing machine equipment, scrapcollection equipmentProcessing equipment• Mixing equipment• Vibrators/tumblers• Plating tank agitation• Laundry equipment• Forming equipment• Parts washers/parts drying equipment/airknives• Plastic pellet drying/conveyingEnergy equipment• Oil atomization, industrial burnersMining and construction equipment• Texture spraying, concrete aeration6 Gast Regenair® Regenerative Blowers www.gastmfg.com

REGENAIR ® Regenerative BlowersRegenair ® Liquid SeparatorThe separator removes liquidsfrom the gas stream in a soilvapor extraction process, tohelp protect both blower andvapor treatment system fromcorrosion and mineral depositbuildup. The separator islocated between the extractionwells and the blower. An inlinefilter is installed betweenseparator and blower.inH 2 0CFMCut away to show ball float. Abovemodel shows optional explosion prooffloat switch AJ213SpecificationsPractical Design Engineered to remove and contain moistureranging from a fine mist to slugs of water from blower inlet airstreams, Gast separators incorporate a cyclonic action whichresults in a very high degree of efficiency. A floating ball valvewhich closes when the liquid level becomes too high preventscollected liquid from overflowing back into the air stream. Whenthe float valve closes an integral vacuum relief valve opens,admitting air to cool the blower and prevent overheating.Rugged Construction Gast separator drums are made fromribbed heavy gauge cold-rolled steel, with heavy steel inlet, drainand float switch ports welded to the drum wall. Drum interiors areepoxy coated to resist abrasion, corrosion and chemicals, whilethe drum exterior is coated with durable urethane. For ease ofconnection, the outlet port of female pipe threaded. The heavyduty304 stainless steel ball float resists chemicals. Maximumrated vacuum is 22 inHg(299 inH 2O).Included is a pilot operated precision relief valve capable offunctioning over a wide duty range. This vacuum relief valve isdesigned and built to proven reliability and durability standards.Moving parts are nickelplated for corrosion resistance andsmooth operation.

(barometric pressure at sea level). The density of such air is0.075 lbs/cu ft. and the specific volume is 13.29 cu ft./lb The specific gravity is 1.0.H 2O CFM vs SCFMThe difference between “Cubic Feet Per Minute” and “Standard Cubic Feet Per Minute” is simply one of air density. The word“Standard”, in this unit of measure, refers to the air being at standard temperature and pressure. In this case it will have standardair density. Regenair blowers performance is stated in terms of CFM, the volume of air they move.Fan LawsThe following fan laws apply for the range of air performance where induction motor-driven blowers operate, that is, under 100inches of water static pressure or vacuum (where it may be assumed that air is incompressible). The fan laws may also be used ifthe pressure of both fan conditions is over 100 inches of water but the pressure change is less than 30%.1.

ReferenceREGENAIR ® Regenerative BlowersPressure Varies In Direct Proportion To AltitudeAt low altitudes in an indoor environment, the small changes in Regenair ® Blower performance are usually ignored.At high altitudes, these changes become significant and should not be ignored.The performance of all regenerative blowers varies directly with changes in air density according to the Fan Laws. These FanLaws don’t apply to our positive displacement pumps. Altitude changes air density as well as air temperature.All the catalog performance tests for Regenair ® Blowers were conducted at an altitude of 635 ft. This makes the Regenair ® Blowerscapable of 2% more pressure than the nominal advertising indicates. So in predicting changes in performance we should use the635 ft. altitude as a starting point.A 10% decrease in air density reduces pressure performance by 10%. For example: if a blower like the R5 produces 110 CFMat 40 inches of water pressure, with a 10% decrease in air density, it will produce this same air flow at 90% of 40” or 36” of waterpressure. The open, no duty flow ratings of any of the blower don’t change with air density changes. The maximum rated pressureor vacuum changes the most.For example, a blower is to operate at an elevation of 5000 feet and is to deliver 60 inches of water pressure gage. What pressureat standard air is required?Let:PB – pressure (standard air) blower = 60 inches of waterPSL – absolute pressure at sea level, inHg. = 29.92 inches Hg.inH 2O – inches of water pressurePA – absolute pressure at altitude, inHg. = 24.89 inches Hg.from table for 5000 feet altitude.PB = InH 2O X (PSL/PA)PB = 60 X (29.92/24.89) = 72 inches of water atstandard conditionsTo determine what pressure a 90 inches of water (standard air) blower will deliver at 5000 feet:Let:PD – pressure delivered by a 90 inches of water(standard air) blowerPD = InH 2O X (PA/PSL)PD = 90 X (24.89/29.92) = 74.9 inches of waterGast offers a program called “REGPER” that calculates changes in performance at 60 Hz. for changes in altitude or air temperatureand the effect of operating with both pressure and vacuum on a blower at the same time.

ReferenceREGENAIR ® Regenerative BlowersSound Pressure Level Decreases With Distance According To This Formula:(SPL)2 = (SPL)1 - 20LOG (d2/d1)Where:(SPL)2 = New Sound Pressure Level(SPL)1 = Original Sound Pressure Leveld2 = New distance from sound generatord1 = Original distance from sound generatorThus, each doubling of distance results in 6 dBa reduction in Sound Pressure LevelNOTE: this formula assumes that no noise is reflected. In a room that reflects most sound energy (having walls with a low noise reductionco-efficient) much less reduction in noise level with increased distance will be observed than is predicted with this formula.Noise Q & AQ. How do I decrease blower noise?A. Common methods used to decrease blower noise include:• Having the cover side face where you want thereduction in noise to be and having sound absorbingmaterial diminish sound reflected from the motor sideof the blower• Checking the supporting structure for rattling• Controlling reflected noise with sound absorbing material• Moving the blower away from the operator, in anotherroom, possibly in a different area or outside.Q. Typically how much does the noise output of Gastblowers vary with changes in pressure or vacuum?A. This varies a lot from model to model with some models littleor no change and with others, as much as 9 dBa.Q. Tyically how much does the noise output of Gast blowerschange between 60 Hz and 50 Hz?A. Generally 50 Hz is 3 dBa quieter than 60Hz but this variesfrom model to model.Q. On Gast dual blowers when do I need the large accessorymuffler?A. These blowers provide silencing for either the inlet or exhaustbut not both. If, for example, the discharge of the bloweris underwater or in some location where the noise passingthrough the pipe is contained and not objectionable noadditional silencer is needed. Where this ringing noise is notcontained and noise control is needed, we manufacture accessorymufflers to greatly reduce noise levels.Q. What happens to the noise when I locate two blowersclose together?A. If the blowers are of the same design they produce soundfrequencies that are close together. These may cause a“beating” change in volume of the blower noise. This isbecause the units are not synchronized. If two small blowersare needed this change in volume can be reduced by movingthem further apart. With larger blowers a dual blower withtwo blowers on one motor will solve this problem.Q. What causes the noise relief valves make?A. Air rush through the valve.Q. How do I control relief valve or bleed off valve noise?A. Attach AJ121 Series silencer on the port of the relief valvethat is open to atmosphere.Contact Gast at 269-926-6171 or www.gastmfg.com with anyfurther questions you may have on reducing blower noise in yourapplication.74 Gast Regenair® Regenerative Blowers www.gastmfg.com

Performance CurvesREGENAIR ® Regenerative BlowersBlower Sound Levels of Gast BlowersData is highest sound level out of 4 places around the blower at1 meter.Data represents average of several units run at nominal voltage.Lowest to highest maximum dba level throughout performancerange is shown.Readings at other than the maximum around the blower at1 meter may be from 2 to 10 dba less than data shown.Readings taken in a laboratory sound room that does not reflectmuch noise.Note: For comparison purposes, some blower manufacturersshow sound data from 1–1/2 meters instead of from 1 meter;also, some blower manufacturers show an “average” sound levelacross performance instead of the full range between minimumand maximum sound levels; either of these methods will providedifferent and usually lower sound levels compared to Gast’ssound level method.60Hz dBa at Pressure 50Hz dBa at PressureR1 59-67 R1 59-64R2 66 R2 61-63R3 67-70 R3 63-68R4 69-73 R4 64-69R4P 69-75 R4P 64-71R5 73-77 R5 71-77R6 73-79 R6 70-79R6P 82-83 R6P 77-80R6PP 77-79 R6PP 73-76R6PS 76-77 R6PS 72-75R7 82-84 R7 77-79R7P 77-80 R7P 74-79R7H 83 R7H 79-8160Hz dBa at Vacuum 50Hz dBa at VacuumR1 58-63 R1 54-60R2 67 R2 63-64R3 67-71 R3 64-69R4 70-72 R4 66-70R4P 73-74 R4P 68-71R5 75-76 R5 71-73R6 78-80 R6 74-77R6P 81-85 R6P 79-81R6PP 81-83 R6PP 78-79R6PS 79-81 R6PS 76-77R7 85-87 R7 79-84R7P 84-86 R7P 80-83R7S 82-83 R7S 78-80R9 85-90 R9 83-84R9P 88-90 R9P 84-87R9S 87-88 R9S 83-86R4H 82-89 R4H 79-88R4M 85-89 R4M 80-85R7H 82-91 R7H 80-90R7S 75-77 R7S 72-76R9 82-85 R9 78-85R9P 81-88 R9P 79-86R9S 79-81 R9S 77-81R4H 80-82 R4H 75-81R4M 82-83 R4M 78-79www.gastmfg.comGast Regenair® Regenerative Blowers 75
