Field Controls introduces the CAS 3 and CAS 4, powerful fan in a can combustion air systems designed to simplify and enhance appliance ventilation. These compact units are equipped with high-performance fans housed in small metal cans, delivering combustion air precisely where it’s needed.

The CAS 3 is specifically designed for oil-burning equipment like furnaces, boilers, and water heaters, featuring a 120-volt safety control circuit. Its versatility allows it to be used with multiple appliances, thanks to the option of a control kit for interfacing with multiple units. On the other hand, the CAS 4 can be utilized with natural gas or LP burning furnaces, water heaters, or boilers with a 24-volt or millivolt control system.

Both CAS models incorporate an internal differential pressure switch that detects airflow blockages. If insufficient combustion air is detected, the pressure switch prevents the equipment from firing, ensuring safe operation.
