The AirTAC GFR300C15AJC2G AirTAC Filter Regulator G1/2 Round Psi Gauge 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 GFR300C15AJC2G is an AirTAC GFR300 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This configuration has a G1/2 (BSPP) port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and a round pressure gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with this automatic drain, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits the 300 size, and no mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with a choice of ports, PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um (code W) filtration, and gauge options. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details for your application before ordering.

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.

Filtered, regulated air feeds clamping cylinders on an automated assembly press, holding a stable set pressure so parts are gripped consistently cycle after cycle.
Point-of-use filtration and regulation ahead of the diverter and stopper cylinders on a packaging conveyor line, keeping moisture and debris out of the actuators.
A clean, regulated air supply feeding the solenoid valve manifold that pilots fill, capping and sorting functions on a bottling line.
Choose the GFR300 size step by matching the port and expected air demand: 300 sits in the middle of the 200/300/400/600 range, and larger sizes carry larger ports and more flow. This unit is fitted with an automatic drain, which suits unattended duty; manual and differential-pressure drain versions exist if you prefer operator-controlled or pressure-differential draining. The 40 um element is the standard grade; specify code W for 5 um where finer particulate removal is needed. The round gauge here reads psi; square embedded gauges and MPa or bar scales are alternatives. PT is the standard thread, with G and NPT available as order options, and a mounting bracket can be added if this no-bracket (J) configuration does not suit your panel. Flow is published as curves, not a single rating, so send us your application details 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 a rated flow number. Tell us your application and we will confirm the flow and sizing details from the datasheet on request before you order.
This code carries an automatic drain, which expels collected condensate from the bowl without operator attention. The GFR300 series is also available with a manual drain for operator-controlled draining or a differential-pressure drain as the default; the drain type also affects the regulator adjustment range, so confirm the version that suits your installation.
