Make-up Air Controls Give Your Tight Home a Breath of Fresh Air
A frequent cause of “sick house syndrome” is negative air pressure buildup—the result of a lack of proper fresh-air exchanges in the home. To help eliminate this problem, Skuttle manufactures two specialized products to provide the fresh air today’s tight homes desperately need. The Model 216 Make-Up Air Control automatically delivers controlled fresh air to solve problems caused by negative indoor air pressure. The D-28-6 Make-Up and Combustion Air Diffuser supply combustion air for fuel-burning appliances.
Skuttle’s popular 216 Make-up Air Control reduces unwanted air infiltration to provide added indoor comfort. Model 216-1 has a 6-in. (15.24 cm) diameter and is appropriate for most installations; Model 216-2 has a 4-in. (10.16 cm) diameter. Both models operate automatically and use no electricity.
How the Model 216 Works
An insulated flex duct connects the unit to a screened, fresh air inlet mounted outside the home. When the furnace blower operates, the air control damper opens, automatically drawing outside air into the furnace. The air is filtered, heated or cooled, then circulated through the home’s duct system. As a result, a slight pressure builds up in the home, keeping untreated air from seeping in around windows and doors.
Features and Benefits
The Skuttle Make-up and Combustion Air Diffuser (Model D-28-6) is designed to supply combustion air to fuel-burning appliances that have inadequate combustible air sources.
How the Diffuser Works
Generally installed 12 inches (30.48 centimeters) from the appliance’s combustion air intake, the Diffuser connects to a 6-in. (15.24 cm) insulated duct which, in turn, connects to a screened, fresh air inlet mounted on the home’s exterior. As the colder, heavier outside air enters the Diffuser, the unit acts as a check valve or cold air trap, automatically diffusing auxiliary combustion air into the area around the appliance.
Features and Benefits
Proper ventilation, in combination with humidification, filtration and air purifications systems can create a healthier, more comfortable environment in your home.
