About APRILAIRE

Aprilaire, a brand of Research Products Corporation based in Madison, Wisconsin, USA, has been a manufacturer of indoor air quality equipment since 1954. The company is known for its focus on whole-home humidification, dehumidification, air purification, and ventilation systems. Aprilaire’s product line includes bypass and fan-powered in-duct humidifiers, dehumidifiers, air cleaners, thermostats, and related controls and accessories. The humidifiers are designed for duct-mounted installation and are rated for daily humidification output ranging from 12 to 18 gallons, with adjustable humidity settings starting at 30%. Dehumidifier controllers, such as model 76, are compatible with Aprilaire dehumidifier models 1830, 1850, and 1870, and are used to manage humidity levels in residential and light commercial spaces. Aprilaire also supplies replacement components including solenoid valves (e.g., model 4040), pumps (e.g., model 4856), drain traps (e.g., model 4842), filter frames (e.g., model 4893), and ionizer wires (e.g., model 4602). These parts are used for maintenance and repair of Aprilaire HVACR equipment. The brand’s products are built to standard industry specifications for residential and commercial HVAC systems, with emphasis on reliability and ease of service. 3G Electric stocks a range of Aprilaire humidifiers, dehumidifier controls, and replacement parts, supporting plant engineers, maintenance managers, and procurement specialists who need to specify or source components for indoor air quality systems. The availability of OEM parts such as pumps, valves, and drain traps ensures that existing Aprilaire installations can be maintained without system redesign. Aprilaire’s product specifications are documented in manufacturer datasheets, and 3G Electric provides access to these details for technical evaluation.
