A remote air manifold is often called a Point-of-Attachment (POA). All of our remote air manifolds meet NIOSH requirements of the 87-116 (1989) document for point-of-attachment.  The Point-of-Attachment (POA) series provides remote manifold capability for respirator users, while complying with NIOSH  regulations. The POA series consists of a regulator, pressure gauge, safety relief valve, and fitting congruency necessary for proper respirator operation. The POA box can be located any distance from the Grade-D filtration Breather Box™ or filtration panel. The remote air manifold (POA) assembly becomes the NIOSH attachment point for the respirators and is now limited to a maximum of 300 feet of breathing air hose at the air outlet fitting on the remote POA box.

Four independent regulators allow each worker to adjust their desired pressure depending on the style or respirator and length of hose.
