The AirTAC GFR30015AJC2TK 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 PT1/2" ports, a automatic 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 GFR30015AJC2TK is a 300-size filter regulator that removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration is fitted with a 1/2 in NPT port, a 40 um filtering element, an automatic drain that expels collected condensate without manual attention, and a round pressure gauge reading in psi. A reverse/check valve is fitted, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits the 300 size frame.
This is a genuine AirTAC part. The GFR family is available in 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drains, a 5 um element (code W) in place of the standard 40 um, gauge and scale choices, and an optional bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.

Feeds clean, regulated air to the cylinders and grippers on a cartoning or wrapping line, with the automatic drain handling condensate on equipment that runs unattended through long shifts.
Serves as the single filter-regulator point for pneumatic conveyer stoppers, diverters and gate actuators, keeping set pressure steady while the 40 um element screens scale and pipe debris.
Supplies regulated air to clamps and swing cylinders on a robotic assembly cell, where the psi gauge gives operators a direct local reading and the check valve holds the setting against upstream dips.
Start with the port and size step: the 300 size carries a 1/2 in port here, and larger sizes carry more flow, so match the step to your line demand - we can confirm exact flow from the datasheet curves before you order. Choose the drain to suit access: automatic (this unit) suits installations that are not checked daily, manual suits attended stations, and differential-pressure draining is the catalogue default. The standard element is 40 um; specify 5 um (code W) if finer particulate control is needed. The round gauge in this configuration reads in psi; square embedded gauges and MPa/bar scales are alternatives. NPT thread is ordered as an option against the PT standard, and a mounting bracket can be added if the J no-bracket build does not suit your panel. 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 GFR300 series as curves rather than a single rated figure, so we do not quote a l/min or SCFM number. Send us your line pressure, set pressure and demand, and we will confirm the flow figures from the datasheet on request before you order.
The A in the code selects the automatic drain, which expels collected condensate from the polycarbonate bowl on its own - useful for equipment that is not checked daily. The catalogue alternatives are the differential-pressure drain (the default) and the manual drain, and the regulator adjustment range differs by drain type: automatic and differential-pressure builds adjust 0.15-0.9 MPa (20-130 psi), while manual-drain builds adjust 0.05-0.9 MPa (7-130 psi).
