The AirTAC GFR30015F2WGK 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 AirTAC GFR30015F2WGK is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This unit is the size 300 frame with a G1/2 (BSPP) port, fitted with the fine 5 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, an embedded square pressure gauge reading in psi, and a built-in reverse (check) valve that holds downstream pressure when the upstream supply is lost. The mounting bracket is included.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, drain types (differential-pressure, automatic or manual), 40 um or 5 um filtration, and gauge choices. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet numbers 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.

Supplying clean, regulated air to the clamp and fixture actuators on a CNC machining cell, with the 5 um element protecting precision clamping valves and the check valve holding clamp pressure if the shop supply drops.
Feeding the stoppers, pushers and diverter cylinders on a packaging conveyor line, where the regulator keeps actuator speed consistent and the differential-pressure drain clears condensate without line stoppages.
Providing filtered, regulated air to pneumatically actuated process and divert valves in a bottling or filling plant, with the psi gauge giving operators a local setpoint readout at the valve cluster.
Choose the size and port step against the air demand of the circuit: this unit is size 300 with a G1/2 port; smaller or larger GFR frames step the port from 1/8 in up to 1 in. Drain type is a real choice: differential-pressure (fitted here) needs no setting, automatic drains on shut-off, and manual requires periodic bleeding. Filter grade is selectable: 40 um standard or 5 um (the W option fitted here) where finer protection is needed. Gauge scale can be ordered in MPa, psi or bar (psi square gauge here), and the K option adds a reverse/check valve. Thread is PT as standard with G (BSPP) and NPT as order options; a bracket is included unless J is specified. Flow is published as curves, not a single rating, so let us 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number that could mislead your sizing. Send us your application details and we will confirm the flow curve and datasheet figures for this unit on request.
The W in the code GFR30015F2WGK specifies the 5 um filter element instead of the 40 um standard, for finer protection of downstream components, and the K specifies a built-in reverse (check) valve that holds downstream pressure when the upstream supply is interrupted. Both are standard catalogue options you can order with or without.
