Tech QEPH - Quick Exhaust Piston Housing

The QEPH is designed to rapidly vent the blast of air that is used to advance the loader. By venting the gas quickly, the loader responds instantly. This equates to faster loading with lower pressure.

The standard A5 piston housing has no venting ports (very bad). X7 Piston housing has forward exhaust ports only (better). Meaning that it only exhausts the air that is in front of the piston....not behind it. Its the air behind the piston that is doing all the work and really needs to be vented in order for faster loading.

The QEPH is a forward and reverse exhaust tube. It exhausts the air in front the piston during the piston stroke and behind the piston at the end of the piston stroke. Venting the air in front of the piston in the early part of the stroke means that less pressure is needed to advance the loader and venting the air behind the piston allows the loader to return faster.
