Looped C-Spool Air Valve Revolutionary new spring design uses stronger, light-weight material for a smoother stroke with less wear and tear of all spool components (fully interchangeable with C-Spool model pumps).

Lube-free Operation Clean, environmentally friendly design is engineered without the need for lubrication. Lube-free operation extends the life of all air motor parts

Independent and Modular Pilot Valve Industry-leading pilot valve system design is fully independent and virtually non-wearing. Static seals are dirt and moisture resistant. Pilot valve and springs are made from high tensile stainless steel that will not bend or rust. Faster cycles with shorter strokes will extend diaphragm life.

Large Diameter Ports Oversized ports allow air contamination to pass through the pump eliminating blockages and freezing.

Reduced Pump Stalling The unique new Looped C-Spool greatly reduces the pump stalling

Resists Freezing Compressed air expands gradually through our innovative staged air chamber exhaust system to reduce freezing. Large air port design allows contaminated air to pass through the pump and out the exhaust.
