DescriptionThe Model 91-HF Filter-Regulator is designed to provideclean, accurate air pressure to valve positioners, and otherpneumatic control equipment. The filter regulator has beenproven to provide long lasting corrosion resistance in harshindustrial environments. The model 91-HF filter regulator isa quality unit that is ideal as an economical alternative forcontrol of process applications.The Model 91-HF is used extensively to supply air topneumatic controllers, transmitters, transducers, valvepositioners, air cylinders, and a wide range of pneumaticcontrol systems.SpecificationsPerformance SpecificationsOutput Range0-120 psig (0-800 kPa)Maximum Supply Pressure150 psig (1034 kPa)Flow Capacity22 SCFM (37.0 m3/hr) at 100 psig (700 kPa)Exhaust Capacity0.1 SCFM (0.17 m3/hr) with downstream pressure 5 psig(35 kPa) above set pointSensitivity1 (2.5 cm) of waterAir ConsumptionLess than 5 SCFM (0.17 m3 /hr)Effect of Supply Pressure VariationLess than 0.2 psig (1.4 kPa) for 25 psi (170 kPa) Features & Benefitsunder variable flow rates and supply pressures.Corrosion-resistant construction - aluminum die-castingsare finished with Irridite and baked epoxy paint.Depth filter -unit comes equipped with high capacity3 micron filter housed in drip-wellSelf-RelievingLow droop at high flow levels - aspirator design helpsmaintain set pressure at higher flow levelsTight shut-off - a soft, rubberized valve provides apositive shut-off and compensates for dirt and otherforeign matterDescriptionThe Model 91-HF Filter-Regulator is designed to provideclean, accurate air pressure to valve positioners, and otherpneumatic control equipment.
