The AirTAC GFR30015MC3T AirTAC Filter Regulator 1/2 in NPT 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 GFR30015MC3T is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air through a 40 um element, then regulates downstream pressure with the standard regulator. This configuration is fitted with a 1/2 in NPT port, a manual drain on the bowl, a round pressure gauge reading in bar, and a mounting bracket. The maximum 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 is published in sizes 200, 300, 400 and 600 with a choice of ports, G/NPT/PT threads, 40 um or 5 um (W) filter grades, differential-pressure, automatic or manual drains, gauge styles and scales, 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 before ordering.

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.
| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 08 = PT1/4", 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. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 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.

Feeds filtered, regulated air to the pneumatic clamps, tool-change cylinders and air blast nozzles on a CNC machining centre, with the 40 um element keeping swarf and pipe scale out of the valves.
Supplies clean, regulated air to the diverters, pushers and sealing cylinders along a bottling or carton packaging conveyor, where the manual drain suits a shift-start maintenance routine.
Installed as a point-of-use filter regulator on a factory air drop serving assembly bench tools and small air cylinders, with the round bar gauge giving operators a local pressure reading.
For this unit the decodable choices are already fixed: size 300 with a 1/2 in NPT port, 40 um filtration, manual drain, standard regulator, round gauge on the bar scale, bracket included, no reverse/check valve. If you are still selecting, step up or down through sizes 200/300/400/600 to match the port and the flow your line needs, choose a manual drain where an operator can bleed the bowl routinely (an automatic or differential-pressure drain suits unattended installations), and pick 5 um (code W) only where finer particulate removal is required. Thread is PT as standard, with G and NPT as order options.
Flow for the GFR300 is published as curves, not a single rated number, so we do not quote a rated flow figure. Send us your application details and we will confirm sizing against the datasheet before you order.
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 GFR300 as curves rather than a single rated figure, so we do not quote a rated flow, Cv or l/min number. Tell us your application and we will confirm the flow data from the datasheet on request before you order.
The M in the code GFR30015MC3T specifies a manual drain, so an operator opens the drain to bleed collected water from the bowl. If the installation runs unattended, the same GFR300 is available with an automatic drain (code A) or the differential-pressure drain (blank) - ask us for the alternative model code.
