AIR CONTROL PANEL
The air control panel is machined from aluminum. Two hoses connect the air control panel to the block. The shaft inflation shut-off valve allows air flow to the shaft or blocks air flow, not allowing the shaft to deflate. The control handle opens air flow into the conduit to propel the pellet or shuttle.
BLOCK and SHAFT
The block is machined from aluminum. The pulling line passes through the center of the block and shaft, connecting to the pellet or shuttle. The shaft control valve pressurizes the shaft bladder and is measured on the gauge.
SAFETY RELIEF VALVE and NOZZLE
The safety relief valve screws into the back of the block, preventing over pressurization of the conduit. After the conduit has been tested to insure air flow, the safety relief valve is replaced by the nozzle.
The shaft secures the block to the conduit and provides an air tight seal when inflated. Shafts are available for 1", 1-1/4", 1-1/2", 2", 3", 4", 5" and 6" diameter conduit.
