The AirTAC GFR300C08MC2T 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 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 GFR300C08MC2T is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built for a 1/4 in NPT port, has a manual drain on the metal filter bowl, 40 um standard filtration, a round pressure gauge reading in psi, and the mounting bracket is fitted. No reverse/check valve is included. The regulator is the standard type with a 0.05-0.9 MPa (7-130 psi) adjustment range, 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 family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and offers drain choices (differential-pressure, automatic or manual), 40 um or 5 um (W) filtration, gauge and thread options, and a low-pressure type. Flow is published as curves rather than a single rating, so ask us to confirm the 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 0.15 - 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.

Feeding clean, regulated air to pneumatic clamps and vises on a machining centre, holding a steady setpoint on the workpiece through the cutting cycle.
Supplying stop-and-sort gates on a packaging conveyor, where filtered air and a stable regulated pressure keep the gate cylinders repeating stroke after stroke.
Preparing air for purge and actuation circuits inside lab analysers, with the round psi gauge giving the technician a local readout of the set pressure.
Size and port set the air capacity: this 300-size unit carries a 1/4 in NPT port; step up to 400 or 600 when the line needs more flow. The manual drain means the bowl is bled by hand - choose automatic or differential-pressure drain if the bowl sits where hand access is awkward. Filtration is 40 um standard; specify the W code for 5 um where finer protection is needed. The round gauge on this unit reads psi; MPa and bar scales are alternatives, and an embedded square gauge is the standard fitting. Thread here is NPT; PT is the standard thread and G (BSPP) is also an orderable option. Flow is published as curves, not a single rating - send us your flow and pressure requirements 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, not as a single rated figure, so we do not quote a number here. Send us your line pressure and required flow and we will confirm the sizing from the datasheet on request.
The code specifies a manual drain: the bowl is bled by hand, which suits accessible mounting points on a maintenance routine. Automatic and differential-pressure drain versions are available in the same GFR300 size if you would rather not rely on manual bleeding.
