The AirTAC GFR300C15AJC2WG AirTAC Filter Regulator G1/2 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 GFR300C15AJC2WG is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one body. This configuration is built around a G1/2 (1/2 in) port, a 5 um filter element (the finer of the two published grades) and an automatic drain that ejects collected condensate without manual attention. The standard regulator covers a setting range of 0.15-0.9 MPa (20-130 psi), a round external gauge scaled in psi is fitted, and the bowl on this size 300 unit is polycarbonate (PC). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. No reverse/check valve is fitted and no mounting bracket is included.
This is a genuine AirTAC part from the GFR300 series. The GFR line is published in four sizes (200, 300, 400 and 600) covering ports from 1/8 in to 1 in, with a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, square or round gauges scaled in MPa, psi or bar, PT (standard), G or NPT threads, and optional brackets. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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, pressure-stable air to tool changers, clamping fixtures and air-powered workholding on a machining centre, with the 5 um element protecting fine control valves downstream.
Regulates supply to filler actuators, capping heads and diverting cylinders along a packaging conveyor, while the automatic drain clears condensate through continuous shifts.
Conditions supply air for lab analysers, sample-handling actuators and test rigs, where the 5 um element guards sensitive pneumatic components and the psi gauge aids repeatable setup.
Choose the size by port and flow: this unit steps up to G1/2 (1/2 in), one of four GFR sizes spanning 1/8 in to 1 in, so match the port to your line and let us check the published flow curve against your demand. On this code the choices are already fixed: 5 um filtration (versus the 40 um standard), an automatic drain (versus manual or differential-pressure), a round psi gauge, a G thread (PT is the standard; G and NPT are order options), and no bracket. If you need the wider 0.05-0.9 MPa setting window, that belongs to the manual-drain variant; this automatic-drain unit sets 0.15-0.9 MPa (20-130 psi). Flow is published as curves, not 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. 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 one number. Send us your line pressure and air demand and we will confirm the datasheet curve and check the G1/2 size against your application before you order.
The code ends in W, which selects the 5 um element instead of the 40 um standard - the right choice where fine valves or instruments sit downstream. The A selects an automatic drain, so condensate is expelled without manual draining; manual-drain variants trade that convenience for a wider 0.05-0.9 MPa setting range.
