The AirTAC GFR30010JC2WK AirTAC Filter Regulator PT3/8, 5 um is a genuine G-series filter regulator: water separation, 5 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 AirTAC GFR30010JC2WK is a size 300 filter regulator that cleans compressed air and sets downstream pressure in a single body. At PT3/8 it combines water and particulate removal with a 5 um filter element (the fine W grade), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a polycarbonate bowl. The fitted reverse/check valve holds the downstream setting if upstream supply is interrupted, and the round gauge supplied reads in psi so the set pressure is visible at the unit.
This is a genuine AirTAC part in the GFR300 series, one of four sizes (200, 300, 400, 600) with port options from 1/8 to 1 inch and thread choices of PT, G or NPT. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range for this configuration 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 the datasheet 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 stamping or assembly cell, the GFR30010JC2WK sits at the drop to the press air line, stripping water and fine particles before the valve stack and holding the clamp circuit at a stable, operator-set pressure read on the psi gauge.
Carton sealers, case packers and labelling heads on a packaging line run best on clean, regulated air; the 5 um element protects the small cylinders and ejector valves, and the reverse/check valve keeps the setting through brief supply dips.
Test rigs and analytical instruments fed from a shop-air header need fine filtration ahead of regulators and transducers; this unit conditions the air at the bench, with the differential drain handling condensate without manual attention.
Size 300 with a PT3/8 port is the right step when your line flow sits above what a 1/4 inch unit carries but below the 1/2 inch class - match the port to your existing pipework and let us confirm the flow curve against your demand before you order. The 5 um W-grade element suits air that feeds sensitive components; the 40 um standard grade is the choice for general shop-air protection if your application allows it. This unit ships as coded with no mounting bracket, a differential-pressure drain, a round psi gauge and a reverse/check valve fitted; if you need a bracket, a square embedded gauge, an MPa or bar scale, or a G or NPT thread instead of PT, those are catalogue options on the same series - tell us and we will quote the matching code.
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 GFR300 series as performance curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the flow from the datasheet for your exact configuration before you order.
The W in the code GFR30010JC2WK selects the 5 um filter grade instead of the 40 um standard, for finer protection of downstream components. C2 selects the external round gauge with a psi scale (MPa and bar scales are also available). Both are catalogue options on the GFR300 series, and the differential-pressure drain is the default for this configuration.
