  • Each 1 PSI difference equals ~1.5% productivity gain or loss

  • Ideal for #7 and #8 nozzles

  • Full-port coupling connections ensure unrestricted airflow

Dual-Chamber Cycle Controls

  • Housed in a NEMA 4-rated enclosure for protection and reliability

Galvanized Piping for Corrosion Resistance

  • 1-1/2″ Piping

  • 2″ Inlet

Heavy-Duty Full-Port Ball Valves

  • Built for long-term durability and consistent performance

Extended Life Schedule 80 Heavy-Duty Nipples

  • Resists abrasive wear for extended operational life

Bolt Clamps on Pusher Line

  • Allow for quick, convenient field repairs

Combination Valve / APVII Valve

  • Two-in-one valve design automates top chamber cycling

  • Quadruple plunger seal design prevents air and abrasive carryover

  • Solid machined tungsten carbide plunger and sleeve for superior wear resistance

  • 1″ NPT cleanout port allows easy access for clearing obstructions and draining

  • Relieving control handle reduces air consumption and shortens stop times

15′ Blowdown Hose Assembly for Remote Mounting

9″ Adjustable Spider

  • Adjustable for various abrasive types and sizes

  • Reduces pop-up sealing strain by supporting abrasive weight

Skirted Pop-Up Gasket

  • Ensures effective sealing by cutting through abrasive material

  • Prevents “burping” issues common with hopper-feed blast pots
