The AirTAC GFR300C15C2WGK AirTAC Filter Regulator G1/2, 5 um 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 GFR300C15C2WGK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This configuration is built with a G1/2 (BSPP) port, the 5 um filtration grade (the finer of the two options), a differential-pressure drain, an external round gauge scaled in psi, and a reverse/check valve fitted. The standard regulator covers a 0.15-0.9 MPa (20-130 psi) adjustment range with a maximum inlet pressure of 1.0 MPa (145 psi), and the unit operates from -5 to 70 C (non-freezing). The 300 size uses a polycarbonate (PC) bowl, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and catalogue options include manual or automatic drains, 40 um or 5 um filtration, embedded square or external round gauges scaled in MPa, psi or bar, PT, G or NPT threads, and bracket choices. 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.

Feeding clean, regulated air to the tool-change clamps and pilot valves of a CNC machining centre, with the 5 um element protecting fine valve spools from particles and the psi gauge giving operators a readable setpoint at the machine.
Regulating supply to the cylinders and grippers on a carton-forming packaging line, where the fitted check valve holds the downstream circuit against supply dips and the differential-pressure drain bleeds condensate without stopping the line.
Supplying the air cylinders that raise diverters and stoppers on a bottling conveyor, keeping pressure steady so actuation timing stays repeatable while the bowl drops out water carried over from the compressor room.
Step through the GFR sizes (200/300/400/600) against the flow your line needs - the 300 size carries a 1/2 inch port. Choose the drain: differential-pressure (as fitted here, the default), automatic, or manual, where the manual-drain version widens the regulation range to 0.05-0.9 MPa. Pick 40 um for general shop air or 5 um (this unit) where downstream pilot valves and instruments need finer protection. On gauges, the embedded square gauge is standard; this unit carries the optional external round gauge scaled in psi, with MPa and bar scales also available. Thread: PT is the standard, while G (this unit) and NPT are order options. A mounting bracket is included on this configuration. Because flow is published as curves rather than a single rated figure, 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 as curves rather than a single rated figure, so we do not quote a number here. Send us your operating pressure and required flow and we will confirm the sizing from the datasheet before you order.
The W in the code selects the 5 um element, the finer of the two grades, suited to protecting pilot valves and instruments downstream. The standard grade is 40 um for general shop air; both are catalogue options on the GFR300. This unit uses the differential-pressure drain, and the regulation range with that drain is 0.15-0.9 MPa (20-130 psi).
