The AirTAC GFR20008C2G AirTAC Filter Regulator G1/4, 40 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 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 GFR20008C2G is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size-200 unit is specified with a G1/4 (BSPP) port, the standard 40 um filter element, a differential-pressure drain, and a round gauge reading in psi (the embedded square gauge is standard; the external round gauge is the optional fitment). The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), the polycarbonate bowl suits the 200 size, a mounting bracket is included, and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working 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 inch, and is orderable with manual or automatic drains, a 5 um element (code W), different gauge scales, and PT, G or NPT threads. Flow is published 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 filtered, regulated air to pneumatic clamps and workholding fixtures on a machining centre, where the 40 um element keeps chips-laden condensate out of the clamp cylinders and the psi gauge lets setters verify clamp pressure at a glance.
Supplies regulated air to divert gates, pushers and sealing jaws on a carton packaging line, protecting the actuators from water carryover while holding a stable setpoint through the shift.
Serves as the point-of-use filter regulator on a bench drop in an assembly plant, giving each station its own clean-air supply and locally adjustable pressure without touching the main line regulator.
Start with the port step: this unit is size 200 with a 1/4 in port; step up to 300, 400 or 600 if the line needs a larger port and more flow. Choose the drain to match maintenance access: differential-pressure (as here, drains when the pressure drop warrants it), automatic for hands-off condensate removal, or manual where an operator drains on a schedule. The standard element is 40 um; specify code W for the 5 um grade where downstream equipment needs finer filtration. Gauge scale is selectable (MPa, psi or bar - this unit is psi), and the thread here is G (BSPP); PT is the catalogue standard with G and NPT as order options. A bracket is included on this unit. Because flow is published as curves rather than a single rating, 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. 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 family as curves rather than a single rated figure, so we do not quote a l/min, m3/h or SCFM number here. Tell us your application and we will confirm the flow and datasheet figures for this unit on request before you order.
A blank drain position in the code means the differential-pressure drain: condensate is expelled when the pressure drop across the element warrants it, with no operator action. The trailing G means the ports are G (BSPP) parallel thread; PT is the catalogue standard thread, and G or NPT are specified at order time - this unit is built with G1/4.
