Attach AIR-O-MATIC to your aeration fan that is attached to your bin.

AIR-O-MATIC is a preheater for the aeration fan with fluctuating air temparatures between approximately 60° F (16° C) to 110° F (43° C). Runs on propane gas or natural gas. Vacuum switch proves the aeration fan is running; the thermostat calls for heat; the electronic ignition lights the burner; air temperature rises to thermostat setting. Burner cuts out, thermostat cools and unit recycles, thus providing a constant warm temperature. No direct flame gases not mixed with the incoming air. Cold air intake between approximately -10° C is warmed to 40° C.
