Regulator Body – Cool Tube / Respirator Cooling System Component

Part Number: 407001-08
Weight: 0.08 lbs

The Regulator Body is a core OEM-compatible component of the RPB® Cool Tube (Cold Air Tube Assembly), responsible for housing and supporting the adjustable airflow mechanism that controls outgoing air temperature. This part serves as the main structural body for the Cool Tube’s regulator system, enabling operators to fine-tune cooled air delivery for maximum comfort in hot, demanding industrial environments.

Crafted from durable, engineering-grade materials, the regulator body is built to withstand abrasive blasting, heavy vibration, high temperatures, and continuous use. Replacing a worn, cracked, or damaged regulator body ensures the Cool Tube continues to perform efficiently and maintains proper cooling functionality.
