The AirTAC GFR300C15AJC2TK AirTAC Filter Regulator NPT1/2 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 GFR300C15AJC2TK is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration is built around a 1/2 in NPT port, drains collected condensate automatically, and carries the standard 40 um filter element. A round pressure gauge reading in psi is fitted, and a reverse/check valve is included in this code. No mounting bracket is supplied with this version.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), embedded square or external round gauges with MPa, psi or bar scales, and G (BSPP) or NPT thread variants alongside the PT standard. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet for your application.

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.

Clean, regulated air to the pneumatic clamps and part-holding cylinders on a stamping cell, where the automatic drain keeps condensate out of the valves during continuous two-shift running.
Air preparation for the pusher and diverter cylinders on a carton packaging conveyor, with the 40 um element protecting directional valves from water and pipe scale.
Filtered, pressure-stabilised air for tool changers, pneumatic vices and air-blast chip clearing on a machining centre, with the psi gauge giving operators a direct readout at the machine.
The real choices within GFR are the size and port step (200/300/400/600, 1/8 to 1 in) matched to the air demand of the equipment downstream; the drain type - differential-pressure as the default, automatic where condensate must clear without attention, or manual where you want positive control; the filter element, 40 um standard or 5 um (code W) for finer protection; the gauge, embedded square as standard or external round, scaled in MPa, psi or bar; and the thread, PT as the catalogue standard with G (BSPP) and NPT as order options. Bracket inclusion is coded, and this unit carries none. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing from 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your operating pressure and the air demand of the equipment downstream, and we will confirm the sizing from the datasheet on request.
This code specifies an automatic drain, which expels collected condensate without manual attention - useful on lines that run unattended. The GFR family is also available with differential-pressure (the default) or manual drains, and the drain type sets the regulator adjustment range: 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drains, or 0.05-0.9 MPa (7-130 psi) with a manual drain.
