120mm PA66 Duct Cleaning Brush
120mm PA66 Duct Cleaning Brush is built for Air Conditioner Filter, Vent & Fin Cleaning where the brush must enter or follow duct walls, louvers, and vents. Head size, working length, stem flexibility, and fill are selected to loosen dust, lint, and pollen without losing access or control.
Product Features
120 mm head cleans compact ventilation ducts — The radial brush reaches the full internal wall.
PA66 bristles remove dust, lint, and loose deposits without metal wire contact — Suitable for routine HVAC cleaning.
Flexible shaft and sectional rod options — The brush can navigate long runs and elbows.
Open fill works with vacuum extraction — Loosened dust can be carried away.
Round and custom profiles — The head can match duct shape.
Working length, PA66 stiffness, shaft, rod connection, and kit contents can be customized.
Product Overview
120mm PA66 Duct Cleaning Brush uses a working section shaped around the available opening, depth, and internal profile. It contacts duct walls, louvers, and vents to remove dust, lint, and pollen; the access path and minimum clearance determine whether the brush needs a rigid stem, a flexible extension, a tapered head, or a stepped cleaning section. The flexible rod, brush diameter, joint, working length, and bend radius must reach the complete passage without separating.
Key dimensions start with Brush head diameter 120 mm, Brush head length 300 mm, and Handle length 600 mm. The brush uses a bore-cleaning structure matched to the diameter, depth, and access path. The specified interface is quick-change coupling. PA66 Nylon are the principal material directions in the current specification. The stroke, guide clearance, and flexible length must be checked against the complete movement envelope.

Application Areas
120mm PA66 Duct Cleaning Brush is primarily mapped to Air Conditioner Filter, Vent & Fin Cleaning. Before using this brush for a new application, check the workpiece surface, debris path, and required finish.
- 120mm PA66 Duct Cleaning Brush is configured for Air Conditioner Filter, Vent & Fin Cleaning.
- The active brush contact follows duct walls, louvers, vents, flexible passages, coils, fins, and air-handling sections while the fill displaces dust, lint, pollen, soot film, and loose grease deposits.
- Use this configuration when the dimensions, access path, mounting interface, operating motion, chemistry, and allowable surface contact match the stated project conditions.
Selection Guidance
Structure fit
Match the tube & pipe bore brush geometry to duct walls, louvers, and vents, the available access, and reciprocating motion. Confirm Brush head diameter 120 mm, Brush head length 300 mm, and Handle length 600 mm against the complete working envelope before finalizing the brush.
Contact material
Choose from PA66 Nylon according to the behavior of dust, lint, and pollen, the surface sensitivity, and any wet, chemical, temperature, or hygiene requirements. To set the right stiffness, confirm the filament diameter, free trim, and density as well as the material.
When to use another solution
For 120mm PA66 Duct Cleaning Brush, use another cleaning method when dust, lint, and pollen cannot be released by controlled filament contact, when duct walls, louvers, and vents cannot tolerate the selected contact material, or when the access path prevents safe engagement and residue removal.
