Airline Respirator Systems - LP

The systems shown combine a mask or hood, air supply hose and an oil-less compressor. They all use AC power from an ordinary wall outlet, and come complete and ready to use.

The respirator and hood systems listed here fall under the heading of Constant Flow Air-Line Respirators. Constant Flow Air-Line Respirators use low pressure air, and are designed to maintain a slight positive pressure of air inside the facepiece or hood, regardless of inhaling or exhaling. This means that should there be a small gap in the seal of the facepiece or hood, any leakage would be directed outward. Because air flow is maintained at all times, constant flow units almost always use a compressor as their air source. This constant flow of air would quickly exhaust the capacity of a cylinder system.

We offer two basic types of Constant Flow Air-Line Respirators: one uses a tight-fitting facepiece (full face or half mask); the other, a loose-fitting hood or helmet. Air pressure from the compressor must be able to maintain at least 4 Cubic Feet per Minute (CFM) for a tight-fitting facepiece and 6 CFM for a loose-fitting hood. The pressure leaving the compressor varies between 10-15 psig, depending on the length of hose and number of devices. Also, depending on the ability to maintain inlet pressure, the length of approved air-supply hose for these systems is usually between 25-100 feet for low pressure systems. Consult the instruction manual for your respirator to determine the specific inlet pressure and hose length.
