Fairchild's Model 21 is an Adjustable Ratio Pneumatic Relay, whereby the ratio of output pressure to signal pressure is infinitely adjustable. The adjustment range permits signal amplification of 1:30 or signal reduction of 30:1 by rotation of the ratio adjustment knob. The Model 21D is available with both input and output adjustable bias. Maximum input bias is 3 psig, with a maximum output bias of 9 psig.

Back Pressure Regulators work well where applications require high precision control of back pressure or relief pressures. The Model 10BP offers high precision, as does the compact Model 30BP. In addition, the Model 50BP Polymer, Model 66BP Stainless Steel, and Model 4000ABP high flow back pressure regulators are designed by Fairchild for tough applications.

Positive and Negative Bias Relays are designed for applications that require an output pressure that is the sum of a controlled input signal plus or minus a fixed bias. Fairchild's line up of biasing pneumatic relay products includes both positive biasing relays, such as the Models 15, 85D and 1500A and relays that handle both positive and negative biasing functions such as the Model 14.

For applications with natural gas media and others which require reliable and accurate explosion proof I/P transducers, our TXPD6000 Voice Coil I/P, E/P Transducer and TXI7800 / TXI7850 Piezo Ceramic I/P Pressure Transducers carry all FM, CSA, ATEX and IECEx agency approvals for years to worry free operation. The TXI8750 incorporates patented technology to provide a moisture resistant I/P unit.

Take full advantage of compressed gases in pneumatic systems. The gas must be adequately prepared. Fairchild's new FR and FRL preparation packages provide clean, dry, lubricated air essential for optimum performance of pneumatic systems. With their modular construction, the FR / FRL units provide compact efficiency, high flow, and superior 5 micron filtration.

High flow and good filtration are critically important and the Fairchild Model 63 and slightly wider Model 65 filter service pressure regulators offer world class performance on both counts. For a service regulator, the Model 64 standard and the Model 66 Stainless Service Pressure Regulators will exceed your expectations.

All of our accessories complement our complete line of control products. Transducer manifold and rack mounting kits, pressure gages, strip pressure gages, panel loading stations, calibrators, automatic drain filters, and natural gas filters offer high quality and precision typical of all Fairchild products.

The Fairchild T7800 series incorporates piezo ceramic disc actuation means while the T7900 and new T1750 series I/P pressure transducers use feed and bleed solenoid technology to provide a complete range of high performance transducers for every application. These electro-pneumatic I/P units are impervious to shock, vibration and positional orientation.

Whether you demand high accuracy, high pressure, high flow, fast response or "all of the above," Fairchild has a complete line of high performance I/P, E/P Transducers to suit your application. From our 1000 psi "BIG BOSS™" T1750, to our 0.15% accuracy T7800 series, Fairchild I/P transducer models handle your toughest challenges.

The Fairchild Models 10 and 81 are ideal for general precision pressure regulator applications, while the compact Models 30 and 80 offer high precision in a small package. The Model 100 high flow regulator, the 1000 no bleed pressure regulator, the 4000A no bleed high flow regulator and the Model 4100A Low Pressure regulator also offer high precision control.

The Process Control line of I/P Transducers utilizes a flapper and nozzle attached to a voice coil to proportionally regulate the output pressure. The Fairchild T5200, T5400, T5700 and T6000 pressure transducer series offer dependable performance at economical prices. The new T6100 I/P unit also offers "Lock in Last Place" reliability in an easy to use product configuration.

Manifold Kits for the T6000, T7800 and T7950 Series Transducers are available for mounting 3, 5, 10 or 15 transducer units. These manifolds have a common supply port to all the transducers. Supply port connections are provided on the end and rear of the manifold. Outlet ports are located on the rear and bottom of the manifold. All T6000, T7800 and T8000 Rack Kits utilize a 10 unit manifold and include additional hardware to permit installation in a standard 19" Rack.

Our Model 70 miniature regulator offers high precision in a tiny package. The new Model 72 High Performance Miniature Regulator features an improved design for even better performance, while the Model 50 Polymer regulator excels in lightweight, medical or tough applications.

Designed for highly versatile control valve designed to perform a number of specialized functions, including averaging, differential, inverting, and totalizing, the Model 22 Pneumatic Computing Relay is a versatile Fairchild product. This high quality unit, which offers up to four inputs as well as positive and negative biasing over a broad range, is available in several configurations to meet most application requirements.

Pneumatic volume boosters feature high flow capacity and fast response. A wide range of signal to output pressure ratios, pipe sizes and options are available in Fairchild's pilot operated regulator booster products with a Cv of 1 up to a Cv of 18, with flow capacities of 45 SCFM, 76.5 m3/hr up to 1500 SCFM, 2550 m3/hr.

Reversing Relays are designed for applications requiring an output that equals a manually preset spring load minus a variable signal pressure. These high quality units, such as the Model 25 and Model 2500A, combine excellent sensitivity with unusually high flow capacity. These Fairchild reversing pneumatic relays are ideally suited for a variety of precision control applications, including converting direct acting valves to reverse action, controlling opposite acting valves from a single transmitter, and cushioning cylinder loads.

The Model 90 Low Pressure and Model 91 High Pressure Selector Relays are designed to select the lower or higher of two signal pressures to provide a continuous output pressure to a control device. The Model 90 and 91 are recommended for dead end or low flow service in critical applications such as control loops requiring precise, automatic monitoring of signal pressures.

The Model 24 Snap Acting Relay is a highly accurate differential relay with snap-acting switching. The output of the unit will go to supply pressure when the signal is equal to or greater than the setpoint. The signal pressure must fall below the set point to return the output to zero. This pneumatic relay's Near Zero Throttling and Pilot Staging result in true snap-action in your application.

In addition to its standard products, Specialty Pressure Regulators, such as its Model 2400 Standard and Low Pressure series Motorized Regulators for automation, and the Model 2800 Plunger Regulator and Model 3400 Lever Operated Regulator, were developed by Fairchild for fast and convenient actuation.

Vacuum Regulators cover all applications from full vacuum in the Model 17 Vacuum Regulator and Model 18 Vacuum Relief Regulator to those in low pressure and lighter vacuum, handled by the Model 16 Vacuum Regulator and the Model 1600 High Flow Vacuum Regulator.
