The AirTAC GFR300C15AJF2K AirTAC Filter Regulator PT1/2 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 GFR300C15AJF2K is a 300-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a PT1/2 (1/2 in) PT thread, an automatic drain that ejects condensate from the polycarbonate bowl without manual attention, a 40 um standard filter element, an embedded square gauge reading in psi, and a reverse/check valve that holds downstream pressure if the supply drops. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include manual or differential-pressure drains, a 5 um element (code W), MPa or bar gauge scales, G (BSPP) or NPT threads, and an optional mounting bracket. Flow for this series is published as curves rather than a single rated figure, so ask us and 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.

Feeds filtered, pressure-set air to tool changers and pneumatic clamps at a machining centre drop, with the check valve holding downstream pressure through supply dips.
Supplies steady regulated air to sorter diverters and stop-gate cylinders on a distribution conveyor, keeping gate actuation consistent across the shift.
Delivers moisture- and particle-controlled air at a set pressure to carton sealers and wrap-tightener cylinders on a packaging line, with automatic drain-off during continuous runs.
Pick the size step (200/300/400/600) against the port and the air demand of your line - this 300 unit sits at PT1/2. Drain choices are automatic (this code), manual, or the differential-pressure default; automatic suits unattended duty, manual suits lines you inspect visually. The element is 40 um standard; specify W for the 5 um grade when downstream equipment needs finer filtration. Gauge scales come in MPa, psi (this code) or bar, threads can be ordered in PT, G (BSPP) or NPT, and a bracket is optional. Flow is published as curves, not a single rating, so send us your application and we will confirm sizing against the datasheet before you order.
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 flow for the GFR300 series as curves rather than a single rated figure, so we do not quote one number. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request.
This code carries an automatic drain, which ejects collected condensate from the bowl without anyone opening it - useful on lines that run unattended. The same 300-size filter regulator can be ordered with a manual drain or the differential-pressure default, and with a 5 um element (code W) if you need finer filtration than the standard 40 um.
