Schaefer Brush 403086 Duct Brush Medium Filament

Product Description

The SCHAEFER BRUSH 403086 is a duct brush designed for cleaning interior duct surfaces in HVAC systems. Fitted with medium-stiffness filaments, it provides enough agitation to break loose accumulated dust, debris, and light buildup without damaging duct liner or sheet metal walls. This type of brush is a standard tool in duct cleaning service work and is used by HVAC technicians and duct cleaning contractors on both residential and light commercial systems. The medium filament grade balances reach and scrubbing action, making it a practical choice for general-purpose duct maintenance work.

This duct brush is suited for routine duct cleaning operations where medium agitation is needed. It is commonly used with flexible duct cleaning rod systems to reach sections of rectangular or round ductwork that are not directly accessible. Residential HVAC service technicians and commercial duct cleaning crews both rely on this brush type for scheduled maintenance and post-construction duct cleaning. It is packaged as a single unit.
