"Control Air delivers precision pneumatic and electropneumatic controls like no one in the business." Products include: precision and general service air pressure regulators, electronic pressure regulators (I/P, E/P), and frictionless rolling diaphragm air cylinders.

The Type-300 Instrument Air Filter Regulator is designed to provide clean, accurate air pressure to instruments, valves, and other automatic control equipment. This filter regulator has been proven to provide accurate operating characteristics under variable conditions. Durable materials and a standard epoxy paint finish provide long lasting corrosion resistance in harsh industrial environments. The Type-300 is a quality unit that is ideal as an economical alternative for control of process applications.

The Type 350/360SS series of stainless steel regulators and filter regulators are designed to stand up to the harshest environments while providing highly accurate pressure regulation. Proven 316 stainless steel housing and filter assemblies along with fluorocarbon diaphragm construction make the 350/360SS compatible with sour gas and adaptable to off shore environments. This quality instrument is economical to buy as well as operate, and provides extremely stable and repeatable control of gas pressure. Oversized valving helps the unit achieve high flow rates with minimal pressure drop.

TYPE 950XP Explosion-Proof I/P Transducer

The Type-950XP Explosion-proof I/P (current to pressure) transducer produces a pneumatic output that is directly proportional to a current input signal.  A closed loop pressure feedback control system provides a highly accurate, stable air pressure output for the operation of actuated valves.  The unit can mount in any position and is vibration insensitive.  It's compact housing and easily accessible ports and adjustments make set-up and installation of the unit simple.  An integral volume booster provides high flow capacity, which increases control speed in critical applications.
