The AirTAC GFR30015C2W AirTAC Filter Regulator PT1/2, 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 GFR30015C2W is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration is threaded PT1/2 (1/2 in), carries the fine 5 um filter element (code W) instead of the 40 um standard, drains condensate by differential pressure, and is fitted with an external round gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). The polycarbonate bowl suits non-freezing installations from -5 to 70 C, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, a choice of PT, G or NPT thread, differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge style and scale, and optional reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

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.

Filtered and regulated air feeding pneumatic clamps, tool-change cylinders and part-ejector actuators on a CNC machining centre, with the 5 um element protecting sensitive directional valves.
Conditioning the air supply to carton-forming and case-sealing cylinders on a packaging conveyor, holding a steady set pressure so box flaps are folded and sealed consistently shift after shift.
Water and particle removal plus set pressure for spray equipment air lines in an automotive refinish booth, where clean, regulated air keeps finish quality predictable.
Step up or down through the 200/300/400/600 sizes and their port sizes (1/8 to 1 in) to match the flow your line needs; this 300-size unit sits at PT1/2. Choose the drain to match how the unit is serviced: differential-pressure (this model) drains automatically as pressure builds, automatic drains on a cycle, and manual drain needs an operator. Pick the 5 um element (this model, code W) where downstream valves and instruments need finer air than the 40 um standard, and choose the gauge style and scale - embedded square or external round, in MPa, psi or bar (this model is a round psi gauge). Thread is PT as standard with G and NPT as order options, and a bracket is included.
Because flow is published as curves and not a single rated figure, send us your application details and we will confirm the datasheet and correct sizing 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 GFR series as curves rather than a single rated figure, so we do not quote a flow number. Tell us your application and line pressure and we will confirm the datasheet and check the sizing against your required flow on request.
The W in the code GFR30015C2W selects the optional 5 um filter grade instead of the 40 um standard. Choose 5 um where downstream valves, cylinders or instruments need finer air; the 40 um element remains available on other GFR300 configurations if your application does not need the finer grade.
