MAS-1 MAKE-UP AIR SYSTEM WITH 6 INTAKE AIR HOOD

Field Controls 46231900 MAS-1 Make Up Air System With 6" Intake Hood And Air Damper What's Included 1- Make-Up air damper with air flow adjustment slide 1- Mounting template 1- 6" intake hood The Field Controls Make-Up Air System consists of a make-up air damper, mounted on the return air duct of an HVAC system, and an intake air hood, installed through an exterior wall, to allow outdoor air into the home, with the two being typically connected by installer-supplied standard 6" galvanized sheet-metal pipe (recommended). This device provides fresh air inflow on demand to minimize house depressurization due to moderately-powered exhausting devices (bath fans, dryers, range hoods, etc.), and for the recommended fresh-air changes per hour (ACH) for good indoor air quality. Features: Pressure activated, fits 6" duct or pipe Voltage 24 Watts 3 Make-Up Air System (MAS)make up air damper Features •Adjustable gate provides precise air flow control •Pressure Activated •Functions with or without the HHSC •Easy to read air flow gauge •No electricity required •24 gauge aluminum coated steel •Corrosion resistant and paintable •Intake air hood included •Quiet operation How It Works The Make-Up Air System (MAS) is a pressure activated damper that opens whenever the central fan is on. It closes automatically when the fan is turned off. The adjustable gate provides precise control of air flow based on the needs of the structure.
