Laundry Dryer Duct Cleaning When a commercial dryer vent is clogged, airflow is reduced and commercial dryers are forced to work harder. This means the air travelling through the ductwork and vents gets hotter and does not dry effectively, which can cause: Potential for lint to ignite as the heated air moves slower and temperature intensifies. Accelerated thermostat and internal sensor failure. Reduction in the lifespan of your appliance. Higher energy consumption. Most commercial dryers come with lint traps, or filters, designed to capture the lint, yet only 30-40% is typically collected. The remainder sticks to the duct work and piping. Lint and other debris builds up over time so it is not ever safe to assume that emptying the filter regularly is enough to protect your property from a dryer vent fire. Some of the signs you need commercial dryer vent cleaning: There is an accumulation of lint or debris on the external vent. The dryer is hot to the touch indicating it is overheating. It takes more than one drying cycle to dry one load. The laundered items smell “musty” after being in the dryer. Laundry Dryer Duct Cleaning Procedure The formal process for all our projects remain the same as it has been stated above for the HVAC system cleaning process. Kitchen Exhaust Duct Cleaning Grease from the kitchen travels into the hood, through the vent hood filters, into ductwork that leads to the exhaust fan on the roof. Grease is a fuel that can ignite with a simple spark from the kitchen cooking line and spread throughout the attic and onto the roof in seconds causing severe damage and potential loss of life. The owner of the exhaust system has the ultimate responsibility to ensure the exhaust system is safe. AIRTECH cleans your kitchen exhaust system from cook-top to roof-top to ensure that your exhaust system is completely cleaned to the NFPA Standard-96. Many of our competitors clean only where you can see and don’t spend time on the areas you can’t. We clean the hood, the entire duct work and the blower fan. We even prove it through our Picture Verification System which we provide on every clean! Having your exhaust system cleaned regularly is not only for the safety of your customer, employees, and your building; it’s mandated by law that you have it done. Kitchen Exhaust System Inspection & Cleaning Schedule It is very typical for a municipality to adopt the standard written by the National Fire Protection Association (NFPA) as the local law or code for building and cleaning commercial kitchen grease hoods. The NFPA is an independent organization, not an arm of the government. The standard that the NFPA has written concerning
commercial kitchens is NFPA 96. Again, NFPA 96 is a standard written by an independent organization, not a law or code until it is adopted as a law or code by the municipality where the cooking establishment is located. Since NFPA is the standard most widely and universally adopted into law, it is the only standard that we will address and follow. According to NFPA 96 – 2011, Section 11.4: “The entire exhaust system shall be inspected for grease buildup by a properly trained, qualified, and certified person(s) acceptable to the authority having jurisdiction and in accordance with Table 11.4.” NFPA 96 – Table 11.4 Type or Volume of Cooking Frequency Cleaning Frequency Systems serving solid fuel cooking operations Monthly Systems serving high-volume cooking operations such as 24-hour cooking, charbroiling, or wok cooking Quarterly Systems serving moderate-volume cooking operations Semi - Annually Systems serving low-volume cooking operations, such as churches, day camps, seasonal businesses, or senior centers. Industrial Duct Cleaning Annually The most important element for keeping your industrial ducting clean has to be the human element. Depending on the extraction system different factors will be working against your ductwork and having Airtech maintain your system will increase its effectiveness and working life. Prevention is always better than the cure and this couldn’t be truer than with ducting. The accumulation of grease, dirt and dust can make for uncomfortable and sometimes dangerous working conditions. Rest assured Airtech has the solution. We offer a one off or regular cleaning program that will eliminate the buildup of grease and grime that is inevitable and it’s this grime that we enjoy to clean. Please use the below table to decide the best cleaning intervals for your duct work. The frequency depends on the usage and the vulnerability of the system to ignition. USAGE (Hours per Day of Operation) Cleaning Frequency Very Heavy Use (16 – 20 hours per day) Monthly Heavy Use (12 – 16 hours per day) Quarterly Moderate Use (6 – 12 hours per day) Semi - Annually Light Use (2 – 6 hours per day) Annually
