Description

The Mosmatic 81.576 is the largest and most powerful tool in the TYR adjustable series. With a 20-inch cleaning diameter, it is designed for massive industrial ductwork, oversized debris chutes, and large storage vessels. The “Adjustable” (ADJ) designation means the spray arms can be pivoted, allowing you to customize the cleaning angle or provide self-propulsion for horizontal runs.

Key Specifications

• Part Number: 81.576

• Diameter: 20 inches (500mm)

• 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 Polished Stainless Steel

Core Features

• Variable Spray Arms: Unlike the fixed versions, this model allows you to loosen the adjustment nuts to change the nozzle angle.

  • Perpendicular (90°): Provides the hardest impact against the walls of large vertical shafts.

  • Angled Offset: Redirects a portion of the water pressure to create a “propulsion” effect, helping the 20-inch frame navigate through horizontal industrial ducting.

• Massive Coverage Area: This unit is ideal for ducts ranging from 20″ to 30″ in diameter. Smaller cleaners often lose too much “punch” (impact force) before the water reaches the walls of a duct this wide.

• Heavy-Duty Carbide Swivel: High-torque Swiss engineering ensures the rotation remains smooth and leak-free, even with the leverage of the long 20-inch arms under 4,000 PSI.

• Stainless Steel Safety Cage: A full-diameter protective shroud prevents the high-speed rotating arms from hitting obstructions, protecting both the tool and the structure being cleaned.

Common Applications

• Large-Scale Trash Chutes: The preferred tool for high-volume waste chutes in stadiums, hospitals, and large industrial complexes.

• Industrial Silos & Tanks: Cleaning the interior walls of large food-grade or chemical storage tanks.

• Municipal Infrastructure: Scouring the walls of large-diameter wet wells and sewer access shafts.

• Commercial HVAC/Exhaust: Removing thick buildup in oversized horizontal ventilation systems where propulsion is required to move the tool.

Setup & Nozzle Requirements

Because of the 20-inch span, this unit requires a high-volume pressure washer (GPM) to be effective. You must install two 1/8″ MEG nozzles.
