The AirTAC GFR200C08C3WTK AirTAC Filter Regulator NPT1/4 5 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 See datasheet 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 GFR200C08C3WTK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This 200-size unit has 1/4 in NPT ports, a 5 um filter element (code W), a differential-pressure drain, and a standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi). A round external gauge with a bar scale is fitted, a reverse/check valve holds the downstream setting, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and in PT, G (BSPP) or NPT thread, with drain, filter grade, gauge and check-valve options to match the unit to the job. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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.

Conditioning the air feeding solenoid valves and clamping cylinders on a machining centre: the 5 um element protects the valves while the regulator holds a steady setting for consistent clamping force.
Supplying filtered, regulated air to the pneumatic diverters and pushers on a bottling or carton-packing conveyor, with the check valve holding the downstream setting if supply pressure dips.
Feeding a service-bench setup where spray guns, blow guns and air tools need clean air at a set pressure; the round bar gauge gives a direct pressure reading at the bench.
Choose the size step (200/300/400/600) and port (1/8 to 1 in) against the air demand of the circuit; this unit is the 200 size with 1/4 in NPT ports. Pick the drain type - differential-pressure (this unit), automatic, or manual - noting that the regulation range differs by drain type. Filter grade is 40 um standard or 5 um with the W code, as fitted here. For gauges, an embedded square gauge is standard and an external round gauge is optional in MPa, psi or bar scales (this unit: round, bar). Thread is PT as standard with G (BSPP) and NPT as order options, and a bracket is included unless code J is specified. Flow is published as curves, not a single rating, so 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 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow from the datasheet on request.
C is the round external gauge option and 3 is the bar scale, so this unit comes with a round gauge reading in bar. The embedded square gauge is the standard alternative, and MPa or psi scales can be ordered.
