CAS-6SK FAN IN A DRUM COMBUSTION AIR SYSTEM WITH STARKAP
Combustion Air Systems
CAS-6 and CAS-7
The Fan-in-a-Drum® is a commercial product designed to deliver combustion air into the mechanical room, boiler room or furnace location to overcome a confined space or inadequate air supply. CAS 6 & 7 are dual volt units for oil or gas applications.
How the CAS-6 and CAS-7 Work
When the thermostat calls for heat, the Fan-in-a-Drum® engages and begins drawing air into the structure. When air flow is established, the pressure switch closes. The CAS sends a signal to the appliance, allowing the burner to fire. The Fan-in-a-Drum® diffuses the outside air into the room near the burner to ensure adequate air for efficient combustion.
