Please Call for Pricing and Availability. The Twin-Air™ Compressor system is designed to provide Grade-D breathing air to 3 workers wearing pressure demand respirators. The TA-3 has twin ASME receiver tanks that act as the mounting frame for the compressor. The use of the receiver tanks provides air that has been cooled to within 10 degrees of the ambient temperature. We’ve added pneumatic tires for ease of mobility in rough terrain and a bottom skid plate for going up and down stairs. This plate becomes the frame for the addition of a reserve air cylinder on the model TA-3EA.COMP-3 Package system includes: Model TA-3 compressor, H-10-5 (1/2” x 10’) connect hose, and BB30-CO3 TA-3 Twin-Air™ Compressor, 115/230 VAC, 1 phase, 2HP, 0ampBreather Box™ filtration package, 3 respirator fittingsBBK-20 Calibration kit for CO monitor - 20 ppm CO, zero air, regulator and case – 17 liter size disposable cylindersBBK-10 Calibration kit – same as above with 10ppm CO gas for Canadian calibrationBB30-FK Replacement filter kit
