Description

The Mosmatic 81.406 is the most compact model in the TYR fixed-arm series. At only 3 inches in diameter, it is specifically designed for cleaning extremely narrow vertical shafts, pipes, and vents that larger tools simply cannot enter. Despite its small size, it maintains the full 4,000 PSI industrial power rating found in the larger models.

Core Features

• Ultra-Small Footprint: With a height of only 2.4 inches and a 3-inch diameter, this unit can access tight corners, small residential vents, and specialized industrial piping.

• Fixed Arm Design (2f): The arms are pre-set at a fixed angle to maximize impact against vertical walls. This makes it a “drop-and-clean” solution for vertical chutes and pipes.

• High-Quality Carbide Swivel: Features the same Swiss-made carbide gasket system as larger Mosmatic cleaners. It is self-lubricating and reinforced with stainless steel ball bearings to handle the high RPMs required for deep cleaning.

• Stainless Steel Cage: The unit is protected by a small, rugged stainless steel cage. This prevents the rotating arms from making contact with the pipe walls, protecting both the tool and the ductwork from damage.

Common Applications

• Residential Venting: Cleaning small bathroom and dryer exhaust vents.

• Pipes and Drains: Maintenance of small-diameter drainage and industrial pipes.

• Restaurant Vents: Reaching narrow “drops” in kitchen ventilation systems.

• Containers: Cleaning the interior of small barrels, totes, and chemical containers.
