The AirTAC GFR40015MJC1T AirTAC Filter Regulator NPT1/2 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 AirTAC GFR40015MJC1T is a filter regulator: one body removes water and particulate from compressed air and sets the downstream pressure. This 400-size unit has 1/2 in NPT ports, a polycarbonate bowl with a manual drain, the standard 40 um filter element, and a round pressure gauge reading in MPa. The standard regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), the unit accepts up to 1.0 MPa (145 psi) inlet, and it operates from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in; PT is the standard thread with G and NPT as order options, and drains, 40 um or 5 um (W) elements, and square or round gauges in MPa, psi or bar scales can be selected. Flow is published as curves rather than a single rated figure, so ask us to confirm 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). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT 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.

Cleaning and regulating the supply at point-of-use drops feeding impact wrenches, nutrunners and clamping fixtures, with the manual drain emptied during scheduled line checks.
Conditioning air to carton sealers, case packers and labeler cylinders, holding a steady set pressure so pick-and-place and pusher motions stay repeatable.
Filtering and regulating supply air to solenoid valves and diaphragm actuators on plant skids, where a manual drain suits a manned utility area.
Size and port set the capacity: this 400-size unit uses 1/2 in NPT threads (PT is the AirTAC standard; G and NPT are order options). Drain choice matters in service: a manual drain needs someone to open it periodically, while automatic and differential-pressure drains discharge condensate on their own - here the code M specifies manual. The 40 um element is the standard grade; a 5 um element (code W) suits finer filtration. This unit carries a round gauge in MPa; square embedded gauges and psi or bar scales are also available. Flow is published as curves, not a single rated figure, 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. 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 GFR series as curves, not as a single rated figure, so there is no honest one-number answer we can state here. Tell us your application and we will confirm the flow and datasheet figures for this 400-size, 1/2 in unit on request before you order.
The M in the code specifies a manual drain: condensate collects in the polycarbonate bowl until someone opens the drain valve. Choose a manual drain where the unit is inspected regularly; choose the automatic option (code A) for unattended installations, or the differential-pressure drain (blank) as the catalogue default.
