The AirTAC GFR300C08MF2TK AirTAC Filter Regulator NPT1/4 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 See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR300C08MF2TK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration takes a 1/4 in NPT port, uses the standard 40 um filtration grade, and drains the metal bowl manually, which supports a regulation range of 0.05-0.9 MPa (7-130 psi). It is supplied with an embedded square pressure gauge reading in psi, a fitted reverse-flow check valve, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -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 a choice of ports, drain types, filtration grades, gauge styles and scales, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, 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 0.15 - 0.9 MPa (20 - 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.

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 filtration and regulation ahead of solenoid valves and workholding cylinders on a machining centre, with the local psi gauge giving operators a visible setpoint at the drop.
Clean, regulated air for bagger and cartoner clamp cylinders, with the manual drain letting maintenance purge accumulated condensate during scheduled stops.
A regulated supply for impact drivers and ratchets at a workstation bench, with the fitted check valve guarding the circuit against reverse flow.
Size and port set the air capacity: this unit is size 300 with a 1/4 in NPT port; step up to 400 or 600 for larger drops, or down to 200 for compact point-of-use installations. Drain choice matters: this code carries a manual drain (regulation 0.05-0.9 MPa / 7-130 psi), while automatic (A) and differential-pressure (default) versions purge the bowl with less attention. Filtration is 40 um standard; order the W code for 5 um when finer protection is needed. The embedded square gauge on this unit reads psi; MPa and bar scales and an external round gauge are catalogue alternatives. Thread here is NPT; PT is the standard and G (BSPP) is also an option. A mounting bracket is included, with a no-bracket (J) version available. 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. 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, not as a single rated figure, so we do not quote a number. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request.
The M code means condensate is released by hand from the metal bowl, and this drain type supports a regulation range of 0.05-0.9 MPa (7-130 psi). If you prefer automatic purging, the A code (automatic) or the differential-pressure default version are available in the same family.
