The AirTAC Airtac GFR Filter Regulator GFR300C10JC1WK 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.
GFR300C10JC1WK is an AirTAC G-series filter regulator with a reverse (check) valve fitted: water and particle filtration plus downstream pressure regulation in one body, with the valve helping hold downstream pressure if the upstream supply drops. This configuration is a 300-size unit with a 3/8 in PT port, the finer 5 um filter element (W), a differential-pressure drain, an external round MPa gauge, and no mounting bracket (J). The bowl on the 300 size is polycarbonate (PC).
This is a genuine AirTAC part, rated for a maximum working pressure of 1.0 MPa (145 psi) and a medium of compressed air only, with a temperature range of -5 to 70 C (non-freezing). With the differential-pressure drain, the regulator adjustment range is 0.15-0.9 MPa (20-130 psi). The G series spans sizes 200/300/400/600 with drain, element, gauge, thread and bracket options; we confirm flow and 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.

Supplying filtered, regulated air to part-holding clamps on a fixture where the check valve helps keep the clamp circuit charged if the main supply is interrupted.
Conditioning the shop-air branch feeding a service bay rig that exercises trailer air components, with clean 5 um-filtered air held at a set test pressure.
Feeding pneumatic indicators and small process actuators from a plant air header, where the finer element and stable regulated output suit sensitive devices.
Choose the size step (200/300/400/600) to match port size and air demand; this 300 unit carries a 3/8 in PT port. Drain types: differential-pressure (standard, as here), automatic (A), or manual (M). The W in this code selects the finer 5 um element over the standard 40 um, and the K suffix adds the reverse/check valve for circuits that must stay pressurized if upstream air falls. Gauge choices are the embedded square gauge or the external round gauge fitted here, with MPa, psi or bar scales. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. No bracket is included (J). Flow is published as curves, not a single rating, so ask us to confirm sizing 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.
No single rated figure is quoted because AirTAC publishes G-series flow as curves. Send us your operating pressure and flow demand and we will confirm sizing against the curves and provide the full datasheet on request.
W selects the finer 5 um filter element instead of the standard 40 um, and K adds a reverse (check) valve so the downstream circuit is not dumped if upstream pressure falls. Drain (differential-pressure here), gauge scale and thread remain catalogue choices.
