The AirTAC GFR30015C2WG AirTAC Filter Regulator G1/2, 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/2" 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 GFR30015C2WG is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration carries a G1/2 (BSPP) port on the 300-size frame, a 5 um filter element (the W grade, finer than the 40 um standard), a differential-pressure drain that bleeds condensate as the pressure drop across the element rises, and a round pressure gauge reading in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the polycarbonate bowl is the specified material for the 300 size.
This is a genuine AirTAC part. The GFR family spans four sizes (200, 300, 400 and 600) with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge and thread options, and an aluminium bowl on the 600 size. 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 or any datasheet figure 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.

Feeding clean, regulated air to gripper and clamp actuators on a robotic welding cell, where weld spatter and compressor moisture make fine 5 um filtration and a stable set pressure part of keeping the cell cycling.
Supplying the tape-head and flap-fold cylinders on a carton sealing conveyor, where the G1/2 port serves the line's main drop and the gauge lets operators check the setting at a glance during changeover.
Conditioning the shop-air feed to a CNC machining centre's tool-change and clamping circuits, where water and chips-laden particulate must be stripped out and pressure held steady for reliable tool clamping.
The real choices on this family: step the size (200/300/400/600) and port (1/8 to 1 in) against the flow your line needs; pick the drain (differential-pressure as here, automatic, or manual); choose 40 um standard or 5 um filtration with the W code; select gauge style and scale (MPa, psi or bar); and choose the thread - PT is the standard, with G and NPT as catalogue options to order. A bracket is included unless the J code is specified. This unit is fixed at GFR300, G1/2, 5 um, differential-pressure drain, round psi gauge, standard regulator, bracket included, no reverse valve. Flow is published as curves, not a single rated figure, so send us your application 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 as curves, not as a single rated figure, so there is no one number we can honestly quote. Tell us your application and required flow, and we will confirm sizing against the datasheet on request before you order.
A differential-pressure drain (the default, blank code) discharges condensate as the pressure drop across the filter element rises. The same family is also available with an automatic drain (code A) or a manual drain (code M); choose based on how the unit is serviced in your installation. We can confirm the drain options on the datasheet on request.
