Operation
The HAF is placed in the breathing-air line between the breathing air source and the respirator supply hose. The HAF is the point of attachment for the respirator hose. Air enters the filter through one of the inlet ports. Moisture is removed by expansion in the outer chamber and is drained through a petcock at the bottom of the unit. The air passes through a replaceable filter cartridge. The outlet pressure is controlled by a regulator on the cap and is measured by a gauge downstream from the cartridge.
Advantages
- One filter suitable for multiple respirators, up to 6 users
