Model 16 Vacuum/Positive Pressure Regulator
Brand: Fairchild Industrial Products
The Rotork Fairchild Model 16 Vacuum Regulator is designed for systems that require 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 16 pneumatic vacuum regulator features control sensitivity of 1/2" 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 16 will handle a 250 psi, 17 bar, maximum supply pressure and offers five (5) output pressure ranges:
- from Vacuum to 2 psi, 0.15 bar, 15 kPa
- up to Vacuum to 150 psi, 10 bar, 1000 kPa
The Rotork Fairchild Model 16 pressure regulator offers up to 40 SCFM, 65 m3/hr positive flow capacity.
