The AirTAC GFR30010JF1TK AirTAC Filter Regulator NPT3/8, Gauge 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 AirTAC GFR300 series is a filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This unit is built with a 3/8 in NPT port, a 40 um filter element, a differential-pressure drain on the polycarbonate bowl, an embedded square gauge scaled in MPa, and a reverse (check) valve fitted. It is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR300 size sits in the GFR range of 200, 300, 400 and 600, with port options from 1/8 to 1 inch and a choice of PT, G or NPT threads. Other catalogued options include a 5 um element (code W), automatic or manual drain, psi or bar gauge scales, an external round gauge and a mounting bracket. Flow is published as curves rather than a single rating, so ask us to confirm the figures for your application from the datasheet.

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 filtered, pressure-set air to the pneumatic clamps and ejector cylinders on a metal stamping cell, with the fitted check valve protecting the set circuit from backflow.
Supplying clean, regulated air to the diverter and stopper cylinders along a carton packaging conveyor, with the square gauge giving the operator a direct MPa reading at the line.
Conditioning supply air for pneumatic actuators on a laboratory or QC test rig, where the 40 um element helps keep water and particles out of precision cylinders.
Choose the size and port by the flow your line needs: the GFR range steps through 200, 300, 400 and 600 with increasing port and capacity, and this unit takes a 3/8 in NPT connection. Pick the drain to suit your maintenance routine - differential-pressure (as fitted here), automatic, or manual; note the regulator range is 0.15-0.9 MPa (20-130 psi) with auto or differential drain and 0.05-0.9 MPa (7-130 psi) with manual drain. Select the 40 um standard element or the 5 um W option, the gauge scale (MPa, psi or bar) and an external round gauge if preferred, and order G or NPT threads explicitly - PT is the standard thread. A bracket is optional; this configuration omits it. Because flow is published as curves rather than a single rating, 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 the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request.
This unit has a differential-pressure drain, the catalogued default, which discharges condensate across the element. Automatic (code A) and manual (code M) drains are also available; note the regulator range is 0.15-0.9 MPa with auto or differential drain and 0.05-0.9 MPa with manual drain.
