Reservoir type humidifiers rely on warm air from the furnace passing through a polyurethane evaporator pad or “Drum” rotating in a reservoir of water. The warm air absorbs the moisture from the pad and returns humidified air for distribution throughout the home. The water level in the reservoir is controlled by an automatic float valve. The motor to rotate the drum is controlled by a humidistat.

These humidifiers rely on warm air from a furnace passing through a moisture laden evaporator panel. A humidistat and solenoid valve control the flow of water to the patented distribution trough where it disperses evenly across the pad. The warm air absorbs the moisture from the panel or pad and is returned to the air stream for distribution throughout the home. Unevaporated water drains from the unit taking troublesome minerals with it. There is no standing water in these humidifiers and maintenance usually consists of annual evaporator pad replacement (frequency of replacement varies with water condition). For additional evaporative capacity (4.3 GPD @ 140º water temp.) all our Flow-Thru humidifiers can be connected to a hot water supply line with ¼” copper tubing.
