The AirTAC GFR40015MLJC2WGK 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 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 GFR400 series is an AirTAC filter regulator: water and particulate removal plus pressure regulation combined in a single body. This configuration is built on a G1/2 (BSPP) port with a 5 um filter element (code W, against the 40 um standard), a manual drain, and the low-pressure regulator type. It is supplied with a round external pressure gauge scaled in psi and a reverse/check valve fitted, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the bowl at this size is polycarbonate (PC).
This is a genuine AirTAC part. The G-series filter regulator line runs from size 200 through 600, with ports from 1/8 to 1 inch, PT as the standard thread (G and NPT are order options), drain choices of differential-pressure, automatic or manual, 40 um or 5 um filtration, gauge scale choices, and bracket options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. 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. |
| 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 air prep for solenoid valve stacks on a carton-forming or case-packing line. The 5 um element reduces particulate reaching the valve spools, and the manual drain lets maintenance staff check the bowl during scheduled rounds.
Fixture and clamp circuits on a machining cell that run at lower regulated pressures than a standard regulator setting. The low-pressure type regulator and round psi gauge make set-and-verify adjustments straightforward at the cell.
Filtered, regulated air to diverter and stopper cylinders along a sorting conveyor. The fitted reverse/check valve helps hold downstream pressure during supply dips, and the G1/2 port suits larger actuator volumes.
Choosing within the GFR line: step through sizes 200 / 300 / 400 / 600 as your flow requirement grows - the 400 size carries a 1/2 inch port. Drain type is a real decision: differential-pressure (the default) drains as upstream pressure falls, automatic drains without operator action, and manual (this unit) requires periodic opening, which suits supervised installations. Filter grade is 40 um standard or 5 um with code W - this unit carries the 5 um element. Gauge scale is MPa, psi or bar; this one is the round gauge in psi. Thread: PT is the standard, with G (BSPP) and NPT as order options - this unit is G. Brackets are optional and this configuration omits one. Flow is published as curves, not 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 this series as performance curves rather than a single rated figure, so no single number can be quoted honestly. Tell us your line pressure and the flow your application needs, and we will confirm the sizing from the datasheet on request before you order.
The M in the code selects the manual drain: an operator opens it periodically to expel collected condensate, which suits supervised installations. The same series is also available with differential-pressure drain (the default) or automatic drain (code A) if you want drainage without operator action.
