Filter Regulators – SANDPIPER Genuine Accessories


SANDPIPER Filter Regulators offer protection for downstream diaphragm pumps powered by compressed air.

Air leaving most compressors is warm, wet, dirty and, often, unregulated. The combination of dirty and unregulated air can damage and/or shorten the life of downstream equipment, such as air-operated double-diaphragm (AODD) pumps.

To alleviate this issue, compressed air should be filtered and regulated. SANDPIPER Filter Regulators remove solid and liquid contaminants to increase the service life of AODD pumps and other air system components.

Filter regulators function both as a filter and pressure regulator, offering protection and precision control. Shipped with a liquid-filled pressure gauge, the elements are sized to optimize SANDPIPER pump performance.

The compact, rugged design provides clean, controlled, consistent air pressure while reducing downtime and maintenance costs. Additional benefits include:

  • Reduced maintenance
    • Clean, regulated air is the key to trouble-free pump operation.
  • Lower operating costs
    • Lowers energy costs through reduced air consumption and less demand on compressors
  • Extended pump life
    • Reduces stress on AODD pump parts by regulating air pressure to the needed amount
  • Pump protection
    • Protects the pump’s main air valve by efficiently removing solid and liquid contaminants from air lines
  • Safe operation
    • Designed to maintain constant downstream air pressure even if upstream conditions vary
  • Easy installation
    • Filters and regulates air supply in a single, easy-to-install unit
  • Precise pump control
    • Easy air pressure adjustment to vary the pump’s flow rate and operate the pump at the desired speed
