The AirTAC GFR40015MJC2G AirTAC Filter Regulator G1/2 - Manual Drain is a genuine G-series filter regulator: water separation, 40 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 GFR40015MJC2G is an AirTAC GFR400 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate down to 40 um from compressed air and holds downstream pressure steady across a 0.05-0.9 MPa (7-130 psi) adjustment range, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating range of -5 to 70 C (non-freezing). This configuration carries a G1/2 (BSPP) port, a manual-drain polycarbonate bowl, a round gauge reading in psi, and no mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, drain options (differential-pressure, automatic, manual), 40 um standard or 5 um (W) filter grades, and gauge, thread and bracket choices. Rated flow is published as curves rather than a single figure, so ask us to 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. 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.

|---|---|
| 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). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.

Point-of-use air preparation for a bottling line's pneumatic actuators: the 40 um element strips water and swarf from the shop-air main while the regulator holds a steady setpoint to the cylinder bank, and the manual drain is bled at shift start.
Clean, regulated air to a CNC machine's tool changer and clamping fixtures: the G1/2 port suits a main-machine supply drop, and the psi gauge lets the setter read the setpoint directly in shop units.
Regulated supply for diverters and stop gates on a distribution-hub sorting conveyor, where steady downstream pressure keeps gate actuation repeatable through the shift and the manual drain clears condensate at the end of each day.
Choose the size and port step against the air demand of your circuit: the GFR400 here carries a 1/2 inch G (BSPP) port, and larger sizes move more air. Drain choice matters: a manual drain needs an operator to bleed the bowl, while automatic and differential-pressure drains discharge condensate on their own - this unit is set to manual. Filter grade is the 40 um standard element, with the 5 um (W) element available as an option. The round gauge fitted here reads in psi; the embedded square gauge and MPa/bar scales are the other options. Thread can be ordered as PT (the standard) or G/NPT, and a mounting bracket can be added. No reverse/check valve is fitted on this code. Because flow is published as curves rather than a single rating, 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR400 flow as curves, not a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the datasheet curve and sizing for your application on request.
The M in the code sets a manual drain: an operator bleeds accumulated condensate from the polycarbonate bowl. If you would rather not do that, the same GFR400 body is available with an automatic or differential-pressure drain - ask us for the matching code.
