The AirTAC GFR30010MC2TK AirTAC Filter Regulator NPT3/8 with Gauge 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 PT3/8" 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 GFR30010MC2TK is a size-300 GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is fitted with NPT3/8 ports, a manual drain bowl in polycarbonate, a 40 um filter element, a round pressure gauge reading in psi, a reverse/check valve, and a mounting bracket. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a choice of ports, thread options (PT standard, G and NPT to order), drain types (differential-pressure, automatic or manual), filter grades (40 um standard, 5 um optional) and gauge scales. Flow is published as curves rather than a single rating, so we 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.
| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". 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. |
| 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. |
| T | NPT 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.

Feeding clean, regulated air to the cylinders and grippers on a carton packing line, with the check valve holding downstream pressure if the supply dips.
A point-of-use filter regulator on the drop feeding conveyor gate and diverter actuators, with the psi gauge letting operators set and verify line pressure.
Mounted on a bracket at a maintenance bench or assembly cell air drop, filtering water and scale from the shop main and regulating pressure for hand-held air tools.
Choose the size and port step against the flow your line needs: size 300 with 3/8 in ports sits in the middle of the GFR range, and the next step up or down changes both port and flow capacity. For drainage, a manual drain means an operator opens the bowl drain periodically - pick automatic or differential-pressure drain instead if the unit will be left unattended. The 40 um element is the standard grade; specify the W option for 5 um filtration. This unit carries a round gauge reading in psi; embedded square gauges and MPa or bar scales are the other catalogue choices. Thread here is NPT; PT is standard and G is also available to order. A mounting bracket is included, and the reverse/check valve is fitted on this code. 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. The reflux valve permits reverse flow 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 we do not quote a number here. Tell us your application and we will confirm the flow figures from the datasheet on request before you order.
The M in the code sets a manual drain: collected water must be drained from the polycarbonate bowl by hand at intervals. If the installation runs unattended, the catalogue offers automatic (code A) or differential-pressure (blank) drain versions instead.
