Description

The Mosmatic 81.466 (TYR-2f) is the largest model in the fixed-arm series, offering a massive 16-inch cleaning path. It is specifically designed for high-production vertical cleaning in large-scale industrial and commercial environments. Because the arms are fixed, this unit provides maximum impact for vertical drops, making it the industry standard for tall, wide structures.

Key Specifications

• Part Number: 81.466

• Diameter: 16 inches (400mm)

• Maximum Pressure: 4,000 PSI (4,500 PSI Max)

• Maximum Temperature: 250°F

• Inlet: 3/8″ NPTF (Female)

• Outlets: 2 x 1/8″ NPTF (Requires two nozzles, sold separately)

• Material: Heavy-duty Polished Stainless Steel

Core Features

• Large-Scale Coverage: At 16 inches, this unit is built for large diameter ducts (16″ to 24″+) where smaller cleaners would lose too much water-impact force over the distance to the wall.

• Fixed Arm Stability (2f): The arms are robotically welded into a fixed position. This ensures they remain perfectly balanced at high RPMs and provide a consistent, aggressive spray angle against the walls of a vertical shaft.

• Precision Swiss Swivel: Powered by the Mosmatic reinforced carbide-seal swivel. It is self-lubricating and designed to withstand the high torque generated by the longer 16-inch rotating arms.

• Protective Outer Cage: Includes a full stainless steel shroud/cage that protects the spray arms from catching on duct seams, rivets, or structural supports during operation.

Common Applications

• Commercial Trash Chutes: The standard tool for cleaning vertical garbage drops in high-rise apartment complexes and hotels.

• Large Restaurant Exhausts: Used in high-volume industrial kitchens with oversized vertical ventilation shafts.

• Manholes and Wet Wells: Cleaning the vertical walls of large municipal sewer access points.

• Industrial Silos & Tanks: Sanitizing the interior of large storage vessels and silos.

Nozzle Selection Guide

To ensure the unit rotates and cleans effectively, you must install two 1/8″ MEG nozzles. The orifice size must be matched to your pressure washer’s GPM to maintain 4,000 PSI.
