Part Number: 407011

The Regulator Assembly for the RPB® Cool Tube is a complete OEM-compatible replacement set that restores full temperature-control functionality to the Cold Air Tube cooling system. This assembly includes the Regulator Body (407001-08), Spindle & Knob (407001-09), and Locking Screw (407001-10)—all critical components that allow operators to precisely adjust the outgoing air temperature for maximum comfort during hot industrial operations.

The regulator controls airflow patterns inside the Cool Tube, enabling users to fine-tune cooling performance based on jobsite conditions. When regulator parts become worn, clogged, or damaged from abrasive environments, replacing the entire assembly ensures reliable operation and restores full air temperature adjustability.
