The Whirlaway Part No: 85.791.009 is a 330 mm rotary arm, typically used in surface cleaners or similar equipment. This component is crucial in high-pressure cleaning applications, ensuring efficient distribution of water or cleaning solutions through its rotating arms. Here's a detailed breakdown of its specifications and features:

Specifications:

Part Number: 85.791.009
Width: 330 mm
Outlets: Two 1/4" NPT Female (NPTF) angled outlets
Inlet: One 1/4" NPT Male (NPTM) inlet
Material: Plated steel

Features:

Rotary Arm Design: The rotary arm design allows for efficient and uniform cleaning over surfaces. As the arm rotates, the angled outlets create a cleaning pattern that maximizes the effectiveness of the pressure washer.
Two Angled Outlets: Equipped with two 1/4" NPTF angled outlets, this arm allows for the attachment of nozzles that spray water or cleaning solutions in a controlled, consistent manner. The angled design helps in creating a spinning action that increases cleaning efficiency.
Standardized Connections: The 1/4" NPTM inlet and 1/4" NPTF outlets are standard pipe thread sizes, making them compatible with various pressure washer hoses and nozzles. This allows for easy integration into existing equipment setups.
Durable Material: Constructed from plated steel, the rotary arm is resistant to corrosion and wear, making it suitable for continuous use in wet environments and with high-pressure water.

Applications:

Surface Cleaners: Commonly used in surface cleaner attachments for pressure washers. The rotary arm’s design enables it to evenly distribute water or cleaning solutions across flat surfaces, making it ideal for cleaning driveways, decks, patios, and other large, flat areas.
High-Pressure Cleaning: Suitable for various high-pressure cleaning applications, especially where a consistent and broad cleaning path is required. The rotating action of the arm helps cover larger areas quickly and effectively.
Industrial and Commercial Use: Often found in industrial and commercial cleaning equipment due to its durability and efficiency in handling high-pressure water jets.
Installation and Use:
Mounting: Ensure the rotary arm is securely attached to the pressure washer's surface cleaner or other cleaning equipment. Proper mounting is essential for safe operation and optimal

performance.

Connection: Connect the inlet of the rotary arm to the pressure washer’s hose or outlet using the 1/4" NPT Male connection. Attach nozzles to the 1/4" NPT Female outlets, ensuring they are securely fastened and compatible with the pressure rating of your equipment.
Operation: When in use, the rotary arm will spin due to the water pressure, creating a consistent cleaning pattern. Always operate the equipment as per the manufacturer's instructions to ensure safe and effective cleaning.
Maintenance: Regularly inspect the rotary arm and its connections for signs of wear, damage, or corrosion. Replace any damaged nozzles or fittings as needed to maintain efficient operation.
