The AirTAC GFR30010JC2TK AirTAC Filter Regulator 3/8 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 PT3/8" 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 GFR30010JC2TK is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air to the 40 um standard grade and holds a regulated downstream pressure adjustable from 0.15 to 0.9 MPa (20-130 psi). This configuration is built with a 3/8 in NPT port, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, a round external gauge reading in psi, and a reverse/check valve fitted to help hold downstream pressure. The polycarbonate bowl suits the size 300 frame, and maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature range of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, a choice of differential-pressure, automatic or manual drain, a 5 um filter grade (code W), gauge scale in MPa, psi or bar, and bracket options. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the flow and datasheet figures for this exact model 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.

Feeding clamp and hold-down cylinders on a machining or assembly fixture, where the filter element keeps swarf-laden plant air out of the valves and the regulator holds a steady clamping pressure. The check valve helps the clamps hold their set pressure through brief supply dips.
Supplying the cylinder bank on a carton-forming or case-sealing machine, where clean, dry, regulated air keeps sealing and ejector strokes repeatable shift after shift. The differential-pressure drain handles condensate without stopping the line.
Conditioning the air feeding grippers and small actuators on a pick-and-place robot cell, where a stable regulated pressure protects the gripper control valve and the 40 um element stops water and pipe scale reaching the end-of-arm tooling.
Size and port set the capacity: the GFR300 with its 3/8 in NPT port sits in the middle of the range (200/300/400/600), so step up to 400 or 600 if the line may grow, or down to 200 if the point of use is small. This unit carries the differential-pressure drain, which needs no operator attention; choose automatic drain (code A) for unattended pits or awkward access, or manual drain (code M) where you want controlled blow-down. The 40 um grade fitted here is the standard choice for general plant air; specify the 5 um W grade only where downstream equipment needs finer filtration. The round gauge reading in psi is the external option - the embedded square gauge is standard and scales are available in MPa, psi or bar. The fitted check valve (K) holds downstream pressure if the upstream supply drops. PT is the standard thread; G (BSPP) and NPT are order options, and this model is supplied with NPT and no mounting bracket.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so we do not quote a flow figure here. Tell us your application and we will confirm the sizing against the flow curve before you order.
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 the GFR series as curves rather than a single rated figure, so we do not quote a flow number for this model. Tell us your line pressure, downstream setting and the equipment you are feeding, and we will confirm the flow from the datasheet curve on request before you order.
The K in the model code means a reverse/check valve is fitted, which helps hold the regulated downstream pressure if the upstream supply is interrupted. The C2 code means the optional external round gauge is fitted and reads in psi; the embedded square gauge is the standard alternative, with MPa, psi or bar scales available.
