RPB Nova 3 Air Inlet Kit

Part Number: NV3-729
Weight: 0.20 lbs

The RPB® Nova 3® Air Inlet Kit is an OEM replacement assembly designed to restore proper air delivery into the Nova 3® supplied-air respirator. This kit includes the essential components required for connecting the breathing tube to the helmet, ensuring a secure, leak-free, and reliable airflow pathway during abrasive blasting and industrial operations.

A properly functioning air inlet is critical for maintaining consistent breathing air supply, helmet pressure, comfort, and NIOSH-compliant system performance. Over time, inlet components may wear due to vibration, debris exposure, or heavy use—making periodic replacement essential for safety and comfort.
