CONOFLOW AIRPAK® FILTER-REGULATOR FR95 Series Conoflow's FR95 Series Airpak®, Filter-Regulator is used to provide clean, accurate air to instruments, valves, positioners, transducers and other pneumatic control devices. This units design provides high flow capability, durable materials of construction and bubble tight shut-off. The FR95 Regulator has a maximum supply pressure capability of 250 PSIG (1724 kPa) with control output settings of 0-25, 0-60 and 0-125 PSIG (0-172, 0-414 and 0-862 kPa). This light-weight unit boasts a high flow delivery rate, excellent droop characteristic and bubble tight shut-off. FEATURE SUMMARY Stable Output High Flow Capability Excellent Droop Characteristics Bubble Tight Shut-Off Low Air Consumption Black Anodized Corrosion Resistant Exterior. This regulator is offered with ¼" NPT inlet and outlet ports, two outlet gauges ports, all aluminum construction and has a black anodized exterior for superior corrosion resistance. A wrench knob adjustment is standard with a handwheel version optional. APPLICATIONS Valve Actuators Pneumatic Positioner Transducers Transmitters Other Pneumatic Control Device The FR95 Airpak® is designed for reliability with an absolute minimum of maintenance. The performance characteristics are a result of Conoflow's high standard of manufacturing and years of experience as a leading producer of pneumatic instrumentation.

PRINCIPLE OF OPERATION Turning the adjusting screw (wrench knob or handwheel) changes the force exerted by the range spring on the diaphragm assembly. In equilibrium, the force exerted by the range spring is balanced by the force from the output pressure acting underneath the diaphragm assembly. An unbalance between the output pressure and the range spring force (set pressure) causes a corresponding reaction in the diaphragm and nozzle assemblies. If the output pressure rises above the set pressure, the diaphragm seat is lifted from the plug, venting the excess pressure to atmosphere until equilibrium...
