The AirTAC GFR20008C2WG AirTAC Filter Regulator, G1/4, 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 PT1/4" 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 GFR20008C2WG is a 200-size filter regulator that removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single compact body. This configuration is fitted with a G1/4 (BSPP) port, a 5 um filter element for finer protection of sensitive downstream components, a differential-pressure drain that bleeds condensate automatically as flow passes through, and an external round gauge reading in psi so operators can check and adjust the regulated pressure at a glance. Maximum inlet pressure is 1.0 MPa (145 psi) and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of ports, thread options (PT standard; G and NPT orderable), drain types, 40 um or 5 um filtration, gauge styles and scales, and bracket options. Flow is published by AirTAC as curves rather than a single rated figure, so we confirm the datasheet and flow 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.

Feeds the clamp cylinders and tool-change actuators on a CNC machining centre, filtering machining-air moisture to 5 um and holding a steady clamping pressure read directly off the psi gauge.
Supplies the air cylinders that push, divert and stop products on a packaging conveyor, with the differential-pressure drain keeping condensate out of the diverter valves during continuous shifts.
Conditions the compressed air feeding sample-handling valves and small actuators on laboratory automation benches, where the 5 um element protects fine pilot valves and the psi gauge allows repeatable low-pressure settings.
Start with size and port: the 200 size with its G1/4 port suits lighter-duty circuits, while stepping up to 300, 400 or 600 buys larger ports and more flow capacity - match the step to the air demand of your circuit. This unit carries the 5 um element (code W); choose 40 um where coarser general-purpose filtration is enough, or 5 um where valves and cylinders need finer protection. Drain choice matters: the differential-pressure drain fitted here needs no operator attention, while an automatic drain (A) or a manual drain (M) can be ordered instead. Gauge style and scale (square embedded or external round, in MPa, psi or bar) and the mounting bracket are also selectable, and PT, G or NPT thread can be specified at order time.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we cannot quote a rated flow here. Ask us to confirm the datasheet and check the curve against your application's flow demand 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 performance curves, not as a single rated figure, so we do not quote a rated flow number here. Contact us and we will confirm the datasheet and read the flow curve for the GFR200 at your operating pressure to check it against your application before you order.
The W in the code GFR20008C2WG specifies the optional 5 um element, which gives finer removal of water and particulate than the 40 um standard grade - useful when protecting sensitive pilot valves or precision actuators. If coarse general-purpose filtration is sufficient for your line, the same size is available with the 40 um element by ordering without the W code.
