Hot Tube – BSP Thread with Belt & Breathing Tube (RPB Compatible)

Part Number: 407024-21
Weight: 1.63 lbs

The 407024-21 Hot Tube with BSP Thread, Belt, and Breathing Tube is engineered to deliver reliable, adjustable heating for incoming respirator air, ensuring maximum operator comfort and safety in cold-weather blasting environments. Designed for compatibility with RPB® Safety systems, this heated air tube assembly helps maintain consistent warm airflow, supporting productivity on long-duration jobs where cold air can impact worker performance.

The internal heating mechanism increases the temperature of compressed air by up to 30°F, helping prevent discomfort, fatigue, and reduced dexterity. The integrated airflow regulator allows operators to fine-tune the outgoing air temperature to suit their specific work environment. Constructed from non-toxic, industrial-grade engineering plastics, the unit is extremely durable and ideal for abrasive blasting, coating, or industrial respirator applications.

A heavy-duty belt provides secure on-person placement, while the included breathing tube ensures total system compatibility and straightforward setup. All components of the 407024-21 are replaceable, and the assembly can be disassembled for cleaning and maintenance.
