The AirTAC GFR30015C2GK AirTAC Filter Regulator G1/2 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 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 GFR30015C2GK is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration has a G1/2 (BSPP) port, the standard 40 um filter element, differential-pressure drainage, a fitted reverse/check valve (code K), and a round gauge reading in psi. The polycarbonate bowl gives a clear view of collected condensate, and the mounting bracket is included for fixing at the installation point.
This is a genuine AirTAC part. The GFR300 series is size 300 within a range spanning sizes 200, 300, 400 and 600, with port options from 1/8 to 1 inch, an optional 5 um element (code W), automatic or manual drain variants, G or NPT thread options, and gauge scale choices of MPa, psi or bar. Max inlet pressure is 1.0 MPa (145 psi), the standard regulation range for this drain type is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so we confirm datasheet figures 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 0.15 - 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.

Clean, regulated air ahead of pneumatic nutrunners and clamps on a vehicle assembly station, with the psi gauge giving operators a local pressure readout at the drop.

Point-of-use air conditioning for a CNC machining center, removing water and swarf-laden particulate before the tool changer and fixture clamping valves.
Size the unit by port and duty: this is size 300 with a 1/2 inch G thread; step up to size 400 or 600, or down to 200, if your line needs a different port. Drain choice matters for the regulation range: automatic and differential-pressure drains (this unit is differential-pressure) give 0.15-0.9 MPa (20-130 psi), while the manual-drain variant widens the range to 0.05-0.9 MPa (7-130 psi). Filtration is 40 um standard; specify code W for 5 um where finer particulate capture is needed. Gauges: an embedded square gauge is standard and an external round gauge is optional, in MPa, psi or bar scales - this unit carries the round psi gauge. Thread is PT as standard with G and NPT as order options; this unit is G (BSPP). A reverse/check valve (K) is fitted and the 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 this series as curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your application and we will confirm the relevant flow and sizing data from the datasheet on request.
K indicates that a reverse/check valve is fitted to this unit. Models without the K code do not carry the valve, so the suffix is the way to tell the two configurations apart when ordering.
