Rotork Fairchild Model 11 regulator

The Rotork Fairchild Model 11 is a regulator which offers high accuracy for applications with very low output pressure ranges. Available in five different ranges, the regulator provides sensitivity of 0.05″ of water column (1.25 mm WC) for easy setting and high repeatability.

The model delivers 24 SCFM (28 L/s) flow capacity and is said to be well equipped to handle difficult applications such as leak detection systems, tank blanketing, air and gas sampling systems, analytical equipment, test stands, and soil and sample testing.

Where envelope size must be minimised the regulator is a suitable solution, as its diaphragm diameter is engineered for optimum performance in a compact package. Tamper proof, screw or standard knob actuation alternatives provide versatility and ease of use and with nitrile or optional fluorocarbon elastomers, the regulator is suitable for many environments.
