Schaefer Brush 406246 Duct Brush Medium Filament

Product Description

The SCHAEFER BRUSH 406246 is a duct brush designed for cleaning the interior surfaces of HVAC ductwork. Fitted with medium-stiffness filaments, it provides effective agitation to dislodge dust, debris, and built-up contaminants from duct walls without causing damage to the duct liner or seams. This type of brush is a standard tool in air duct cleaning operations, used during routine maintenance and remediation work. At 3.3 pounds, the 406246 is durable enough for repeated professional use across residential and light commercial duct systems.

This duct brush is suited for use in forced-air heating and cooling systems where duct cleaning is required. It is commonly deployed by HVAC technicians and duct cleaning specialists working on rectangular, round, or flexible duct runs. The medium filament rating makes it appropriate for standard sheet metal ductwork where a soft filament would underperform and a stiff filament could risk surface damage.

Key Features

• Medium-stiffness filaments balance effective cleaning with surface protection
• Sized for professional duct cleaning applications in residential and light commercial systems

Compatibility

Installation Notes

Duct brushes are typically used by HVAC technicians or certified duct cleaning professionals. Before beginning any duct cleaning operation, shut down the air handling unit and disconnect power at the disconnect or breaker. Ensure all supply and return registers are properly sealed or masked to contain loosened debris. Follow applicable NADCA guidelines and local codes when performing duct cleaning services.
