The AirTAC GFR30015C2WGK 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 GFR30015C2WGK is an AirTAC GFR300 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is a 1/2 in G-thread (BSPP) unit with a 5 um filter element, differential-pressure drain, polycarbonate bowl, an external round gauge scaled in psi, a fitted reverse (check) valve and a mounting bracket. The regulating range is 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and options for drain type, 40 um or 5 um filtration, gauge style and scale, PT, G or NPT thread, and bracket choice. Flow is published as curves rather than a single rated figure, so ask us to confirm datasheet figures for your application on request.

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.

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

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 filtered, regulated air to the pick-and-place cylinders on a bottling or carton-packing conveyor, where the 5 um element helps protect directional valves from water and debris.
Supplying regulated air to tool-clamp and chip-clearing circuits on a CNC machining centre, with the psi gauge giving operators a local setpoint readout at the machine.
Point-of-use conditioning at a paint booth air drop, where cleaner, moisture-reduced air at a stable set pressure keeps spray guns and air motors working consistently.
Choose the size by port and required flow: this unit is size 300 with a 1/2 in G port, and larger sizes carry greater flow. Drain options are differential-pressure (this unit, which bleeds collected water in relation to flow), fully automatic, or manual. Filter grade is 5 um here (code W) against the 40 um standard - choose 5 um where downstream valves, cylinders or instruments need finer protection. The gauge on this unit is an external round type scaled in psi; an embedded square gauge and MPa or bar scales are the alternatives. Thread is G (BSPP); PT is the standard thread and NPT is also an order option, and a mounting bracket is included. Flow is published as curves, not a single rating, so 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 GFR300 flow as curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow and datasheet figures for GFR30015C2WGK on request.
The W code on this model specifies the optional 5 um element, which filters more finely than the 40 um standard to better protect sensitive valves, cylinders and instruments. This configuration also has a differential-pressure drain and a fitted reverse (check) valve, with a round psi gauge for setting the regulated pressure.
