Model 55 Miniature Precision Regulator
Brand: Fairchild Industrial ProductsThe Rotork Fairchild Model 55 is a compact precision polymer pressure regulator for high performance applications where space or weight may be limited or material compatibility concerns dictate use of a polymer construction regulator.
Stability of regulated pressure is maintained under varying flow conditions through the use of an aspirator tube which adjusts the supply valve in accordance with the flow velocity.
The Model 55 pneumatic regulator features control sensitivity of 5" water column to deliver consistent and reliable precision accuracy to maintain your desired set point regardless of supply pressure changes or conditions.
The Fairchild Model 50 pressure regulator will handle a 150 psi, 10 BAR maximum supply pressure and offers four (4) set point pressure ranges from 0-10 psi, 0-0.7 BAR, 0-70 kPa up to 2-100 psi, 0.1-7 BAR, 15-700 kPa.
