  • High-strength lightweight aluminum constructions make them perfect for robotic arms where total weight is at a premium
  • Simple to assemble with two button head screws and an O-ring seal — reducing leakage and lowering installation cost
  • Integrated mounting holes eliminate mounting brackets and allow components to attach directly as standalone units
  • High-flow design with minimal pressure drop ensure air preparation products will not constrain pneumatic system operations
  • Wide range of filter elements (particulate, coalescing, and adsorbing) permits maximum filtration flexibility
  • Combination coalescing filter/regulator with 3-micron pre-filter saves space and capital expense
