Schaefer Brush 403126 Duct Brush Medium Filament

Product Description

The SCHAEFER BRUSH 403126 is a duct brush designed for cleaning interior duct surfaces in HVAC systems. It features a medium filament stiffness, which provides effective agitation of debris, dust, and particulate buildup without damaging duct liners or coatings. This type of brush is a standard tool in duct cleaning operations, used by HVAC technicians and indoor air quality professionals during system maintenance and remediation work. The medium filament grade suits a wide range of duct materials and is appropriate for routine cleaning cycles where a soft filament would be insufficient and a stiff filament would risk surface damage.

This duct brush is suited for residential and light commercial HVAC duct cleaning applications. It is typically used with flexible or rigid rod systems to reach through straight runs, elbows, and branch ducts. HVAC service technicians and duct cleaning crews deploy brushes of this type during scheduled maintenance, post-construction cleanouts, and air quality improvement projects. The medium filament makes it a versatile choice across sheet metal, fiberglass duct board, and flex duct systems where controlled agitation is required.

Key Features

Installation Notes

Duct brushes of this type are installed and operated by HVAC technicians and certified duct cleaning professionals. Before beginning any duct cleaning work, shut down the air handling unit and seal off supply and return registers as required by the cleaning procedure. Verify that the brush diameter and filament type are appropriate for the duct size and material before use. Follow applicable NADCA guidelines and local codes for duct cleaning practices and containment procedures.
