The AirTAC GFR40015JF2WG 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 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 GFR40015JF2WG is a size 400 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration has G1/2 (BSPP) ports, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically when flow resumes, and a square pressure gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the regulated outlet range is 0.15-0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing. The polycarbonate bowl suits this size; only the 600 size uses an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR400 series is one of four sizes (200/300/400/600) with ports from 1/8 to 1 inch, and the catalogue offers drain types, 40 um or 5 um elements, gauge styles and scales, PT/G/NPT threads and bracket options. Flow for this series is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures on request before you order.

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. |

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 to a mid-size pneumatic press or clinching station, where the 5 um element protects valve spools and the regulator holds a consistent working pressure stroke to stroke.
Point-of-use air preparation for cartoning and wrapping machinery, giving the machine's directional valves dry, filtered air at a set pressure without adding oil mist to the packaging area.
Supplying pick-and-place and clamping circuits in an assembly cell, where a stable regulated pressure keeps gripper and cylinder forces repeatable and the 5 um grade guards fine control valves.
Size 400 with 1/2 in ports sits in the upper-middle of the GFR range; step up to 600 or down to 300 depending on the air demand of the circuit, and ask us to check the flow curve against your application. This unit pairs a 5 um element with a differential-pressure drain: choose the 40 um grade if general upstream protection is enough, and manual or automatic drains if the installation cannot rely on differential bleeding. The fitted square gauge reads psi; MPa and bar scales and an external round gauge are catalogue options. Thread here is G (BSPP); PT is the standard and NPT is an order option, and the J code means no mounting bracket is fitted.
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 GFR400 series as curves, not as a single rated number, so we do not quote a figure. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
The W code selects the finer 5 um element instead of the 40 um standard, suiting circuits with sensitive valves. The blank drain position is the differential-pressure type, which discharges collected condensate automatically as flow resumes - no manual draining routine, and no drain fitting to spec.
