By running off of air from the marker itself, the Cyclone Feed system allows Tippmann users to have a marker and loader in one. But, this also limits the loading speed of the Cyclone. The QEPH was designed to remedy this problem. The QEPH exhausts the air that is used to drive the Cyclone once that air has been used to advance the loader, making room for air from the next shot. By exhausting air both before and after each shot, the QEPH allows the Cyclone to cycle much faster due to the exhaustion of any back pressure that may have slowed it down.
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.
While some other piston tubes do exhaust some air, none are as extreme as the QEPH. No QEV or small hole can vent air like the precise slots on the QEPH.
The QEPH is 100% made in the U.S.A. It is machined from 6061 aircraft grade aluminum and is then annodized and teflon coated for the smoothest and most durable finish. Plastic just doesn't cut it...
If you want your Cyclone Feed to keep up with the speed of your marker, then the original QEPH is a must have.
