The AirTAC GFR300C15AJF2WK AirTAC Filter Regulator PT1/2, 5 um 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 GFR300C15AJF2WK is a filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single GFR300 body. This configuration carries a PT1/2 (1/2 in) port with PT thread, a 5 um filter element for finer particulate capture than the standard 40 um grade, an automatic drain that expels collected condensate without manual attention, an embedded square gauge reading in psi, and a built-in reverse (check) valve that holds downstream pressure when the upstream supply is lost. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing. No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and is ordered with your choice of drain type, filter grade, gauge and scale, thread (PT standard, with G and NPT as catalogue options), bracket and check valve. Flow is published by AirTAC as curves rather than a single rated figure, so ask us to confirm the datasheet and flow 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.

Mounted at the drop of a stamping press air line, this unit filters mill moisture and scale from the shop supply at 5 um and holds a steady regulated pressure to the press cylinders, with the check valve holding the set pressure if the main supply dips.
On a carton-sealing or wrapping conveyor, the GFR300C15AJF2WK conditions the 1/2 in feed to the diverters and clamps: clean, dry-enough air at a fixed setting, with the automatic drain keeping condensate off the valves between shifts.
At a distributed air drop serving assembly-cell cylinders and air tools, this filter regulator gives each cell its own filtered, regulated supply independent of neighbours, with the psi gauge letting technicians verify setpoints at a glance.
Step up or down through the GFR sizes (200 / 300 / 400 / 600) and their matching ports (1/8 in to 1 in) according to the air demand of the circuit; the 300 size with its PT1/2 port suits lines fed at 1/2 in. Choose the drain to match maintenance reality: automatic drain (this unit) for unattended or hard-to-reach installations, manual drain where an operator is on hand, or the differential-pressure default. Pick the 5 um element (code W, as here) when finer particulate protection is needed, or the standard 40 um for general-duty prep. Select the gauge scale you want to read - MPa, psi or bar - and remember PT is the standard thread while G (BSPP) and NPT are order options. Brackets are optional on GFR units.
One honest note before you order: AirTAC publishes filter-regulator flow as curves, not a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm sizing and the datasheet figures against the curve before you commit.
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 GFR flow as performance curves rather than a single rated figure, so we do not state a flow number here. Tell us your inlet pressure, set pressure and expected air demand, and we will confirm the sizing against the datasheet curve on request before you order.
Both are decode choices in the model code. The A position selects the automatic drain, which ejects collected condensate on its own instead of waiting for a manual drain pull - useful where the unit is mounted high or visited infrequently. The W position selects the 5 um filter element instead of the standard 40 um grade, for finer particulate removal ahead of sensitive valves and cylinders.
