Breathing Air

Breathing air panel that includes filtration for Class D breathing air. The breathing air panel filtration also removes smell and tastes that air compressors produce.

The breathing air panel will support up to 2 operators. The breathing air panel will be installed and then breathing air lines will be run to the blast booth. A breathing air test port will be installed for testing. This way you will only have to perform one breathing air test.

The system will include breathing air lines for 2-operators. The breathing air lines will be matched to the Bullard blast helmet being supplied per OSHA regulations on breathing air hose and helmet must be of same manufacture from the point of attachment (POA) to the helmet.

The interior of the booth will have a visual and audible signal to warn the operators of low flow or C/O within the breathing air. This warning will also shut off the blast hose inside the booth until the breathing air issue is corrected.

The installation also includes all the copper piping and fittings that are required.
