The AirTAC GFR40015MLC2WGK 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 AirTAC GFR40015MLC2WGK is a GFR400-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a G1/2 (BSPP) port on the size-400 frame, with a 5 um filter element for finer filtration than the standard 40 um grade, a manual drain for the polycarbonate bowl, a low-pressure regulator type, a reverse/check valve fitted, and an external round gauge reading in psi. The maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and is configurable by drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional), gauge style and scale, thread (PT standard, with G and NPT as order options), reverse/check valve and bracket. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application on request.

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.

|---|---|
| 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. |
| (blank) | Mounting bracket included. |
| (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.

Filtering and regulating the air feeding a bank of directional control valves on a packaging or assembly machine, with the 5 um element protecting valve internals from fine contamination.
Conditioning supply air on a plant line that runs at reduced pressure, where the low-pressure regulator type matches circuits that operate well below standard working pressure.
Supplying cleaned, regulated air to bench-mounted test rigs and lab apparatus, with the psi-scaled round gauge giving a direct pressure readout at the point of use.
Start with size and port: the 400 frame with a 1/2 in port suits lines where larger supply piping feeds the unit, but the right step is set by the flow your circuit actually needs - we confirm that against the published curves before you order. This unit is already fixed with the finer 5 um element (choose 40 um where only coarse water and particle removal is needed) and a manual drain, which you operate by hand; automatic or differential-pressure drains suit unattended installations. The fitted round gauge reads in psi; embedded square gauges with MPa, psi or bar scales are the alternative. Thread is G (BSPP) here, with PT as the standard and NPT available to order, and a mounting bracket is included.
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 series as performance curves rather than a single rated figure, so we do not quote one number. Tell us your operating pressure and air demand and we will confirm the datasheet curve figures for this exact model on request before you order.
The M in the code specifies a manual drain: condensate collected in the polycarbonate bowl is released by hand, which suits attended installations. The GFR400 series is also available with automatic or differential-pressure drains for unattended duty - ask us for the alternative code.
