Bullard DC5040 Dual-Cool Supplied-Air Temperature Controller

Bullard DC5040 Dual-Cool provides cooling to both a compatible supplied-air respirator and a Bullard DC70 cooling vest from one flow-control setup, helping manage breathing-zone and body heat in hot work.

• Dual-zone cooling: Directs cooled air to the respirator and body-cooling vest at the same time.
• Designed for Bullard supplied-air systems: Use with the compatible respirator, breathing tube, airline and DC70 vest configuration specified by Bullard.
• Connection choices: Select the quick-disconnect fitting and material that match the approved airline setup.

For respiratory use, supply clean, breathable Grade D air or better from a compressed-air source. Do not use the DC5040 with a low-pressure ambient-air pump. Bullard requires a breathing-air compressor capable of at least 30 cfm per wearer. Use the approved Bullard breathing tube and air-supply hose for the selected respirator configuration, and operate within the specified pressure range. Bullard does not recommend cooling incoming air below 70°F because ice can form in the breathing tube and reduce airflow.
