The AirTAC GFR300C15JF2GK 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 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 GFR300C15JF2GK 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 a 300-size unit with a G1/2 (BSPP) port, standard 40 um filtration, a differential-pressure drain on the polycarbonate bowl, an embedded square gauge reading in psi, a fitted reverse (check) valve, and no mounting bracket. Regulated pressure is adjusted across 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature range of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including 5 um (W) filtration, automatic or manual drains, square or round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads, and mounting brackets. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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 0.15 - 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.

On a bottling plant's capper and rinser stations, this unit filters water and particulate out of the shop air and holds cylinder pressure at the setpoint the machine was set up for, while the check valve keeps downstream pressure stable during upstream dips.
Feeding clamp cylinders on a machining cell, the 40 um element protects the directional valves from debris and condensate, and the square psi gauge lets the setter read and hold the clamping pressure the fixture was qualified at.
Supplying diverter gates and stoppers on a packaging conveyor line, this unit gives a clean, regulated air supply at one point of use, with the differential-pressure drain shedding collected water as air flows through during production.
Choose the size by the flow your line needs: the 200, 300, 400 and 600 sizes step up in port and capacity, and this 300-size unit carries a G1/2 port. Drain type matters in service: the differential-pressure drain fitted here works automatically with air flow, while automatic (A) and manual (M) drains are order options. Filtration is 40 um standard; specify W for a 5 um element where finer protection is needed. The embedded square gauge here reads in psi, with MPa and bar scales and an external round gauge available. Thread: PT is the AirTAC standard, with G (BSPP) and NPT available to order, and brackets are optional. 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 rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm the datasheet curve and the correct size for your application on request.
K means a reverse (check) valve is fitted, so air cannot flow back through the unit toward the filter bowl. It is an option across the GFR range, and units without K have no check valve. This configuration also carries a square psi gauge, no mounting bracket, and a G (BSPP) thread; PT is the standard thread and NPT is available to order.
