Model 1600A High Flow Vacuum Regulator

Brand: Fairchild Industrial Products
The Rotork Fairchild Model 1600A Vacuum Regulator is designed for systems that require high flow and system pressure control above and below atmospheric pressure. Stability of regulated vacuum or pressure is maintained under varying flow conditions through the use of an aspirator tube which adjusts the inner valve in accordance with the flow velocity.

The Model 1600A precision vacuum regulator features control sensitivity of 1" water column and a balanced supply valve to deliver consistent and reliable precision accuracy to maintain your desired set point regardless of supply pressure/vacuum changes or conditions. 

The Fairchild Model 1600A will handle a 250 psi, 17 BAR, maximum supply pressure and offers three (3) output pressure ranges from Vacuum-10 psi, Vacuum-0.7 BAR, Vacuum-70 kPa, up to Vacuum-150 psi, Vacuum-10 BAR, Vacuum-1,000 kPa. The Fairchild Model 1600A pressure regulator offers up to 28 SCFM, 48 m3/hr vacuum flow capacity.
Features
  • The single unit controls vacuum and positive pressure
  • High Flow Capacity
  • Control sensitivity of 1" water column
  • Large Supply and Exhaust Valves
  • Soft Supply and Exhaust Valve
  • Balanced Supply Valve
  • Aspirator Tube compensates downstream pressure droop under flow conditions
  • Separate Control Chamber isolates the diaphragm from the main flow
  • Unit construction
