The AirTAC Airtac GFR Filter Regulator GFR300C15AJF1 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 AirTAC GFR300C15AJF1 is a G-series filter regulator that cleans compressed air and regulates downstream pressure in a single body. This version is the size 300 unit with a PT1/2 port, an automatic drain that empties the polycarbonate bowl on its own, the standard 40 um filter element, and an embedded square pressure gauge scaled in MPa. Maximum inlet pressure is 1.0 MPa (145 psi) and, with the automatic drain, the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing. As a J-coded unit it comes without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, differential-pressure, automatic or manual drain, 40 um or 5 um elements, G (BSPP) or NPT thread options, gauge variants and optional brackets. Flow is published as curves rather than a single rating, so we will 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.

Conditioning and regulating the air feeding a six-axis robot's gripper manifold, keeping grip pressure consistent from part to part on the assembly line.
Serving as the point-of-use filter regulator on a 1/2 inch plant-air drop above a maintenance bench, with the automatic drain handling condensate between jobs.
Supplying the feed and drive cylinders of an automated screwdriving station, where the 40 um element and steady regulated pressure keep the cycle repeatable.
Choose the size 300 body with its 1/2 inch PT port when your line's flow and piping step up from the smaller 200 series; 400 and 600 sizes serve heavier demand, and G (BSPP) or NPT threads are orderable alternatives to the PT standard. The A code gives you automatic drainage - the low-effort choice against manual (M) or the differential-pressure default. This unit carries the 40 um standard element; specify W for the 5 um grade where finer filtration is wanted. The square gauge reads MPa, with psi and bar scales available in the family, and a bracket can be added if the J configuration is not what you need. Because flow appears only as published curves, ask us to confirm sizing against the datasheet 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 G-series flow as curves rather than a single rated number, so we do not state one figure here. Send us your inlet pressure and demand and we will confirm the datasheet curve values for this PT1/2 filter regulator on request.
Yes. PT is the standard thread for this model, and G (BSPP) and NPT are catalogue thread options on the same size 300 body. Any thread choice keeps the same 1/2 inch port, 40 um element, automatic drain and square MPa gauge.
