Model 500 Series Parts
Replaceable components for Aprilaire Model 500 humidifiers. Distribution trays, scale control insert more. All parts are shipped in "single" carton quantities.
The Models 500 and 500M were first introduced in 2007. This unit is a "bypass" humidifier. The Model 500 and 500M replaces the Models 550, 550-A and 558.
A bypass humidifier gets its air movement through the Water Panel® by the differential pressure between the supply (hot air) plenum and the return (cold air) duct. The supply plenum is under positive pressure and the return duct is under negative pressure. The bypass humidifier can be installed either on the supply plenum or on the return duct with equal effectiveness. It will have no adverse effect on any component in the furnace, air cleaner or filter.
