The AirTAC GFR30008MC2TK AirTAC Filter Regulator, 1/4 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 PT1/4" 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 GFR30008MC2TK is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration has a 1/4 in NPT port, a manual-drain polycarbonate bowl, a 40 um filter element, an external round pressure gauge reading in psi, a built-in check valve, and a mounting bracket. Downstream pressure is set within the 0.05-0.9 MPa (7-130 psi) adjustment range, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and with manual, automatic or differential-pressure drains, 40 um standard or 5 um (W) filtration, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and full 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.

| (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.

Setting steady regulated pressure to pneumatic clamps and tool-changer cylinders on a CNC lathe, with the 40 um element keeping particulate-laden shop air out of the machine's valves.
Feeding filtered, regulated air to diverter gates and pusher cylinders on a parcel-sort conveyor, where the manual drain is emptied during scheduled line stops.
Conditioning air for carton-sealer and wrapper cylinders on a packaging line, with the built-in check valve helping hold the set pressure if the upstream supply dips.
Size and port step up together: this unit is size 300 with a 1/4 in NPT port; sizes 400 and 600 carry larger ports and higher flow capacity. Drain choice matters: this unit has a manual drain, suited to periodic draining and allowing the wider 0.05-0.9 MPa (7-130 psi) setting range; automatic and differential-pressure drains are the alternatives. Filter grade is 40 um standard; specify code W for 5 um. The gauge here is a round external type reading psi; an embedded square gauge and MPa or bar scales are the other options. Thread comes as PT standard, with G (BSPP) and NPT as order options, and a mounting bracket is included. Flow is published as curves, not a single rating, 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 GFR300 as curves, not a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and the full datasheet figures on request.
The M in the code selects a manual drain: condensate is released by hand at service intervals. On GFR units a manual drain also allows the wider 0.05-0.9 MPa (7-130 psi) regulator setting range. This unit is fitted with a round gauge reading in psi.
