Description

The Mosmatic 81.566 is a high-performance, large-diameter duct cleaner from the TYR series. Unlike the “fixed” models, the Adjustable (ADJ) version features a rotating arm design where the spray angle can be manually tuned. This makes it incredibly versatile, allowing you to switch between “aggressive cleaning” for vertical drops and “propulsion mode” for horizontal pipe runs.

Key Specifications

• Part Number: 81.566

• 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: Reinforced Stainless Steel

Core Features

• Adjustable Spray Arms: This is the standout feature. By loosening the adjustment nut, you can tilt the nozzles.

  • 90° Angle: Best for deep cleaning the walls of large vertical chutes.

  • Tilted Angle: Creates a “jet-propulsion” effect that helps pull the cleaner through horizontal ductwork or around slight bends.

• Large 16″ Diameter: Designed for larger industrial ducts, commercial kitchen exhausts, and oversized trash chutes where a smaller cleaner would lose impact force before hitting the walls.

• High-RPM Carbide Swivel: Uses Mosmatic’s signature Swiss-engineered swivel system. It is designed to withstand the torque generated by the 16-inch arms while maintaining a leak-free seal at 4,000 PSI.

• Impact Protection Cage: The large diameter is protected by a heavy-duty stainless steel cage to prevent the arms from snagging on duct joints or damaging the internal structure of the vent.

Common Applications

• Large Industrial Chutes: Perfect for multi-story apartment trash and laundry chutes.

• Horizontal Ducting: The adjustable arms make it the preferred choice for long horizontal runs in HVAC or exhaust systems.

• Industrial Tanks: Used for cleaning the interior walls of large chemical or food-grade storage tanks.

• Vertical Shafts: Ideal for elevator pits or large-scale utility shafts.
