The AirTAC GFR400C15JF2W AirTAC Filter Regulator PT1/2, 5 um 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 GFR400C15JF2W is a size 400 filter regulator that removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration carries a PT1/2 (1/2 in) PT thread port, a 5 um filter element (one step finer than the 40 um standard), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element is high enough, a standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi), and an embedded square gauge scaled in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The 400-size bowl is polycarbonate (PC), and no mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR filter-regulator line spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, square or round gauges scaled in MPa, psi or bar, G or NPT thread options, and bracket or no-bracket mounting. Flow is published as curves rather than a single rating, so ask us to confirm the figures against your application before ordering.

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.

Clean, regulated air feeding tool-clamp cylinders and chip-clearing blasts on a machining centre, where the 5 um element protects fine valves and the square psi gauge gives the setter a direct readout at the machine.
A point-of-use station on a cartoning or wrapping line, conditioning and regulating air for pick-and-place cylinders and sealing jaws, with the differential-pressure drain keeping condensate off the downstream valves.
A half-inch drop from the main ring main serving an assembly cell, where one body filters the shop air to 5 um and holds a fixed working pressure for air tools, clamps and small actuators.
Size and port step up together: 200, 300, 400 and 600 cover 1/8 in through 1 in, so match the size to the air demand of the circuit rather than to the pipe alone. Drain choice matters in practice: differential-pressure drain (this unit) needs no attention but only purges when the element loads up; automatic drain purges on a cycle; manual drain needs someone to open it. The 5 um element (code W) suits instrumentation and finer pneumatic work, while the 40 um standard element suits general plant air. Gauge scale is selectable (MPa, psi or bar) and this code carries the embedded square gauge in psi. Thread is PT as standard, with G (BSPP) and NPT available to order; brackets are optional. Because flow is published as curves and not a single rating, ask us to confirm sizing from the datasheet 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and required flow and we will confirm the sizing from the datasheet on request before you order.
This code carries the 5 um element (option W), one step finer than the 40 um standard. It suits circuits with finer pneumatic valves, instrumentation or air bearings; the 40 um grade is the usual choice for general plant air. Both grades are available across the GFR range, so pick per circuit rather than per plant.
