The AirTAC GFR40015MJF2WK AirTAC Filter Regulator PT1/2 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR40015MJF2WK is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is size 400 with PT1/2 (1/2 in) PT threads, a 5 um filter element (code W, against the 40 um standard), a manual drain on the polycarbonate bowl, an embedded square gauge reading in psi, and a built-in reverse/check valve (code K). No mounting bracket is fitted (code J).
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options for drain type, 40 um or 5 um filtration, gauge scale and G/NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. For this manual-drain unit the regulator adjusts from 0.05-0.9 MPa (7-130 psi). Flow is published as curves rather than a single rating - ask us to confirm the datasheet figures for your application.

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 0.05 - 0.9 MPa (7 - 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.
| GFR400 | G-series filter regulator, 400 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| 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. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Point-of-use conditioning for a CNC machining cell: filtered and regulated air to fixtures, clamps and air-powered tooling on a 1/2 in drop, with the check valve holding the set pressure upstream of sensitive actuators.
Supplying steady regulated air to the cylinders, diverters and stop gates on a packaging or bottling conveyor, where the 5 um element helps protect directional control valves from particulate carryover.
Conditioning the air feed to spray guns on a paint finishing line, where stable regulated pressure and 5 um filtration support a consistent finish and protect the gun's air passages.
Choose the size by port and required flow: 200, 300, 400 and 600 step up in port and capacity - this unit is size 400 with PT1/2. Drain type is a real choice: manual (as here, which widens the regulating range to 0.05-0.9 MPa), automatic, or differential-pressure. Filter grade is 40 um standard or 5 um with code W, fitted on this unit. The square gauge can be ordered with MPa, psi or bar scales (this one reads psi), and code K adds a reverse/check valve. Thread is PT as standard; G (BSPP) and NPT are order options. A bracket can be specified in place of the J (no bracket) code. Flow is published as curves rather than a single rating, so 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR400 as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and datasheet figures for this unit on request.
This unit has a manual drain (code M): the polycarbonate bowl is drained by hand as part of routine checks. On manual-drain GFR units the regulator adjusts from 0.05-0.9 MPa (7-130 psi), while automatic and differential-pressure drain versions adjust from 0.15-0.9 MPa (20-130 psi). An automatic-drain version can be ordered if you prefer not to drain by hand.
