The AirTAC GFR40015AJF2WG AirTAC Filter Regulator G1/2, 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/2" ports, a automatic 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 GFR40015AJF2WG is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your set point in a single body. This configuration has a G1/2 (BSPP) port, a 5 um filtration element, an automatic drain that ejects collected condensate without manual attention, and an embedded square gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). The bowl on this size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of automatic, manual or differential-pressure drains, 40 um standard or 5 um (W) filtration, embedded square or optional external round gauges with MPa, psi or bar scales, and G or NPT threads as order options (PT is the standard thread). Flow is published as curves rather than a single rated figure, so ask us to confirm datasheet 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.

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

Feeds spray guns with air that is free of water and fine particulate and held at a stable set point, so finish quality does not drift as the booth runs through a shift.
Sits upstream of the carton-sealing and case-erecting cylinders on a packaging line, keeping their operating pressure constant while the 5 um element guards the valve stack.
Prepares the air feeding a machine's directional-valve manifold: filtered to 5 um, regulated to the circuit's set point, with the psi gauge giving operators a visible line check.
Size steps from 200 through 600, so pick the size whose flow curve covers your air demand with margin - we confirm the curve on request before you order. Drain type matters: automatic suits unattended duty, manual suits periodic checks, and differential-pressure drainage relies on a steady flow. Filtration is 40 um as standard; the W code on this unit selects the finer 5 um element for protection of valves, cylinders and instruments. Gauges are the embedded square type (this unit reads psi) with an external round gauge optional, threads are PT standard with G and NPT as order options, and this code (J) omits the mounting bracket.
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 this family as curves against inlet pressure and setting, not as a single rated number, so we do not quote a figure here. Tell us your operating pressure and air demand and we will confirm the sizing from the datasheet on request.
The W code fits a 5 um element instead of the standard 40 um, giving finer protection for directional valves, cylinders and instruments. The A code makes the drain automatic, so condensate is ejected during operation without manual draining - useful where the unit is mounted in a hard-to-reach spot.
