Generalaire 4886 Germicidal Uv Replacement Lamp 36W 24V

Product Description

The GENERALAIRE 4886 is a germicidal UV replacement lamp designed for use in ducted HVAC systems where biological contaminants in the airstream need to be controlled. Rated at 36 watts and 24 volts, this lamp installs inside the air duct using a magnetic mounting bracket that attaches to a steel mounting plate. The magnetic mount allows for secure, tool-minimal positioning directly on the duct wall. Licensed HVAC technicians typically handle installation and periodic lamp replacement as part of routine indoor air quality maintenance.

This lamp is a direct replacement for the GENERALAIRE MS24 UV germicidal unit. It is suited for residential and light commercial ducted air handler and furnace systems where a UV lamp is installed in the supply or return air duct to reduce airborne and surface biological contaminants. Replacement intervals vary by application, but annual replacement is common practice to maintain effective UV output as lamp intensity degrades over time.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut off system power at the disconnect or breaker before accessing the duct or lamp assembly, and allow the existing lamp to cool completely before handling. UV lamps produce radiation hazardous to eyes and skin — never energize the lamp outside the duct or without eye protection. Follow all local mechanical codes and the equipment manufacturer instructions for lamp orientation and minimum duct clearances.
