The AirTAC GFR20008C3T AirTAC Filter Regulator NPT1/4, Bar Gauge 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 GFR20008C3T is a size 200 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in one body. This configuration has a 1/4 in NPT port, a 40 um standard filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a round pressure gauge reading in bar. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). The polycarbonate bowl includes a mounting bracket.
This is a genuine AirTAC part. The GFR line is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options including automatic or manual drains, a 5 um element (code W), alternative gauge scales, G or NPT threads, and a low-pressure regulator type. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing or any datasheet figure for your application before ordering.

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.

Point-of-use air preparation for a stamping or forming press actuator: the 40 um element keeps water and swarf out of the valve stack while the regulator holds a set working pressure for consistent stroke force.
Feeding pick-and-place cylinders and diverters on a packaging conveyor, where the differential-pressure drain clears condensate during continuous running and the bar gauge lets operators verify set pressure at a glance.
Conditioning the air feed to laboratory automation and test-rig actuators, where the compact size 200 body, bracket mounting and round bar gauge suit a bench-mounted drop with a stable regulated supply.
Start with the size and port: 200 through 600 step up in port size and flow capacity, so match the size to the air demand of the circuit rather than to the pipe alone. Drain choice matters in practice: the differential-pressure drain on this unit suits lines with steady flow, while an automatic drain (code A) suits intermittent flow and a manual drain (code M) suits low-duty points. The 40 um element is the standard grade; specify the 5 um W option where downstream equipment needs finer filtration. Gauge scale is selectable (MPa, psi or bar) and this unit carries a round bar-scale gauge; PT is the standard thread with G and NPT as order options, and a bracket is included.
Because flow is published as curves and not as a single rated number, send us your application details and we will confirm the right size 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 GFR series as curves rather than a single rated figure, so we do not quote one number. Tell us your application and required flow, and we will confirm the correct size against the datasheet on request before you order.
The differential-pressure drain on this unit bleeds collected condensate automatically as air flows through the bowl, with no operator action. It suits lines with steady flow; for intermittent or low-flow duty, the automatic drain (code A) or manual drain (code M) versions are the better choice.
