Description

The Mosmatic 81.456 (TYR-2f) is a professional-grade, 12-inch fixed-arm duct cleaner designed for heavy-duty industrial and commercial applications. It is the “go-to” tool for cleaning vertical structures like trash chutes, restaurant vent hoods, and manholes.

Key Specifications

• Part Number: 81.456

Core Features

• Fixed Arm Design: Unlike the “Adjustable” models (which allow you to change the spray angle for horizontal pipes), this Fixed (2f) version is engineered specifically for vertical drops. The spray angle is set to provide optimal impact against the walls of a chute or duct.

• Maintenance-Free Swivel: Features a high-quality Swiss-made carbide seal system and self-lubricating stainless steel ball bearings, ensuring longevity even with hot water and chemicals (pH 3–12).

• Stainless Steel Cage: The rotating arms are protected by a robust stainless steel “shield” or cage. This prevents the arms from hitting the sides of the duct, which could damage the swivel or the ductwork.

• Vibration-Free: The arms are precision-welded and balanced by robots to eliminate dangerous vibrations at high RPMs.

Common Applications

• Kitchen Exhausts: Removing baked-on grease in restaurant vent hoods.

• Trash Chutes: Sanitizing vertical garbage drops in apartment buildings.

• Tanks & Totes: Cleaning the interior of industrial containers.

• Manholes: High-pressure washing of vertical shafts and sewer access points.
