You can't afford down time, especially when your shop is small and your work force depends on equipment performance. The Mini Fire-Ball 225 is an engineered design with fewer moving parts, which means less wear out, and reduced downtime and more profit for your business. Durable Casting - Thick cast aluminum air motor housing offers unmatched durability. Fewer Repairs - Fewer moving parts in the air motor assembly means less downtime and low repair cost. Extended Seal Life - In-line pump design aligns the air motor piston and fluid piston rods to maximize seal life. Reduce Downtime - Displacement rods have minimal wear due to a proprietary Graco manufacturing process. Superior Sealing - Non-metallic poppet valves offer positive sealing performance, even with contaminated "dirty" air environments for long life without repair. Reduced Icing - Large air porting design provides efficient use of compressed air supply for continuous pump operation and reduced icing. Corrosion-Resistant - Corrosion-resistant design utilizes liquid salt nitriding, nickel plating, stainless steel, aluminum and chrome on key components for longer life.
