Humidifiers

Our humidifiers are 100% evaporative, ad-ding moisture in the form of water vapor only. They are clean operating. The nuisance of airborne water droplets or mineral dust is avoided.

We carry two styles of humidifiers. See below for more information about the types of humidifiers we carry.


Flow-through humidifier that’s ideal for most homes. No bypass required. Installs on vertical warm air supply or cold air return plenum. A motor-driven fan directs a portion of the heated air through the water-soaked evaporator pad. The warm air absorbs moisture and return through internal baffles to the primary war 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. Note: 140° hot water supplied to the humidifier in heat pump applications will increase capacity by 4.3 GPD. Dependable stainless steel solenoid valve with monel wire mesh filter that protects the precision machined Teflon flow control orifice. Saddle valve supplied. Evaporator pad designed for high output with minimal hard water scale accumulation. 16 wide x 14 high x 10 inches deep. Six inch diameter bypass cover supplied. UL listed. Uses 1/4″ copper tubing. High capacity 5/8″ drain and hose prevents clogging. Includes 15 foot vinyl hose. Single plenum design fits minimum space situations. Motor-driven fan eliminates bypass pipe. May be installed on upflow, counterflow or horizontal furnaces or air handlers. 24 V 60 Hz. H-86 wall/duct mount humidistat. Thumbscrews allow easy access to the distribution trough, drain pan and evaporative pad for quick, easy cleaning and service. Simple removable back cover allows easy access to electrical components. Most important components are included. Outboard and keyholed screw holes and simple thumbscrew assembly speeds installation. Patented water distribution tray reduces need for critical leveling. Guarded fan blade assures safety.


Flow-through humidifier that’s ideal for most homes. Installs on vertical warm air supply or cold air return plenum. 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 through-out the living area. A solenoid valve and patented distribution tray meter disperse water uniformly across the evaporator pad. Unevaporated water drains from the unit. Note: 140° hot water supplied to the humidifier in heat pump applications will increase capacity by 4.3 GPD. Dependable stainless steel solenoid valve with monel wire mesh filter that protects the precision machined Teflon flow control orifice. Saddle valve supplied. Evaporator pad designed for high output with minimal hard water scale accumulation. 15 wide x 11 1/2 high x 9 inches deep. Six inch diameter bypass cover supplied. UL listed. Uses 1/4″ copper tubing. High capacity 5/8″ drain and hose prevents clogging. Includes 15 foot vinyl hose. Right or left hand bypass installation. May be installed on upflow, counterflow or horizontal furnaces or air handlers. 115 V 60 Hz. Manual air shutter for summer shut-off affords control of output. Thumbscrews allow easy access to distribution trough, drain pan and evaporative pad for quick, easy cleaning and service. Most important components are included. Outboard and keyholed screw holes and simple thumbscrew assembly speeds installation. Patented water distribution tray reduces need for critical leveling.
