Model 64 Service Regulator
Brand: Fairchild Industrial ProductsThe Rotork Fairchild Model 64 service regulator is a general purpose regulator (does not have a filter).
The Model 64 service regulator has wider port to port mounting dimensions (3.15", 80 mm) making it the choice for field replacement of older style Fairchild and competitive service regulators that have wider mounting port spacing.
The Model 64 pneumatic regulator is similarly well suited to general purpose service regulator applications as it has the highest flow capacity of any regulator in its class.
In addition, the Model 64 features control sensitivity of 1" water column and an integral relief valve to deliver consistent and reliable performance to maintain your desired set point regardless of supply pressure changes or conditions.
The Fairchild Model 64 will handle a 300 psi, 20 BAR, maximum supply pressure and offers three (3) output pressure ranges from 0.5-30 psi, 0.03-2 BAR, 3-200 kPa, up to 2-120 psi, 0.14-8 BAR, 14-800 kPa.
The Fairchild Model 64 pressure regulator offers up to 25 SCFM, 42.5 m3/hr flow capacity.
