EVAPORATIVE PRINCIPLE GENERALAire humidifers are 100% evaporative, adding moisture in the form of water vapor only. They are clean operating. The nuisance of airborne water droplets or mineral dust is avoided. Forced warm air heating systems create a pressure differential that diverts some heated air to the humidifier through a bypass duct. There, the warm air absorbs moisture from a water-soaked evaporator pad and then rejoins the primary warm air stream for distribution throughout the living area. A solenoid valve and patented distribution tray meter and disperse water uniformly across the evaporator pad. Unevaporated water drains from the unit. A motor-driven fan directs a portion of the heated air through the water-soaked evaporator pad. The warm air absorbs moisture and returns through internal baffles to the primary warm air stream for distribution throughout the living area. A solenoid valve and patented distribution tray meter and disperse water uniformly across the evaporator pad. Unevaporated water drains from the unit.
EVAPORATIVE MEDIA 990-13 Evaporator Pad. Designed for high output with minimal hard water scale accumulation. UL listed. 990-13 Evaporator Pad. Designed for high output with minimal hard water scale accumulation. UL listed.
