Custom Cleaning Brush
200mm PA66 Large Duct Brush
200mm PA66 Large Duct 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
200 mm head provides full-wall contact in larger ducts — The brush removes dust, lint, and loose buildup.
PA66 bristles combine resilience with useful scrubbing force — Suitable for repeated HVAC maintenance.
Sectional rods and flexible shafts extend reach — The system can navigate long runs and bends.
Open radial fill allows vacuum airflow — Loosened debris can be extracted.
Round and shaped versions — The brush can match circular or rectangular passages.
Filament stiffness, rod system, connection, head profile, and working length can be customized.
Product Overview
200mm PA66 Large Duct 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 200 mm, Brush head length 400 mm, and Handle length 800 mm. The design follows a tube and bore-brush format for radial contact on internal surfaces. 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
200mm PA66 Large Duct Brush is primarily mapped to Air Conditioner Filter, Vent & Fin Cleaning. If the brush will be used on a different job, confirm the surface, debris discharge path, and acceptable finish first.
- 200mm PA66 Large Duct 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 200 mm, Brush head length 400 mm, and Handle length 800 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 200mm PA66 Large Duct 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.
