The AirTAC GFR Filter Regulator GFR400C15F2WT is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR series is a filter regulator: compressed air is cleaned of water and particulate, then held at a set downstream pressure in one body. GFR400C15F2WT is the 400 size with 1/2 in NPT ports, a 5 um filter element, a differential-pressure drain on the polycarbonate bowl and an embedded square gauge scaled in psi. Maximum inlet pressure is 1.0 MPa (145 psi); with the differential-pressure drain the regulated output spans 0.15-0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing, and the medium is compressed air.
This is a genuine AirTAC part from the G series, which runs from size 200 to 600 with 40 um standard or 5 um fine filtration, differential-pressure, automatic or manual drains, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm flow and full datasheet details on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeding clean, regulated air to the swing clamps and support cylinders on a CNC machining fixture, with the 5 um element helping keep water and dirt carried in compressed air out of the clamp valves.
Providing the filtered pilot supply for pneumatically actuated ball and butterfly valves on a water treatment dosing skid, with the regulator set to the actuator's rated pressure.
Supplying the compressed-air side of single-stage vacuum ejectors on a robotic pick-and-place cell, where filtered, regulated air keeps the ejector nozzles from fouling.
Step through the G series by size - 200, 300, 400, 600 - as port size and flow capacity rise; the 400 frame with 1/2 in ports suits lines with heavier demand. The remaining choices are real code positions: drain (differential-pressure here, automatic or manual to order), filter grade (40 um standard, 5 um as selected), gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and bracket. Because flow is published as curves, not a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes G-series flow as performance curves, not as a single rated figure, so there is no one number we can quote honestly. Send us your supply pressure, downstream demand and allowable pressure drop, and we will confirm the flow data and the full datasheet on request.
Yes. Gauges come in MPa, psi or bar scales, and the thread is available as PT (standard), G (BSPP) or NPT. Drain type (differential-pressure, automatic or manual) and filter grade (40 um standard or 5 um fine) are selectable too. Tell us the variant you need and we will confirm the correct order code.
