The AirTAC GFR200-08C2WTK AirTAC Filter Regulator NPT1/4 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 GFR200-08C2WTK is a size-200 filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This configuration carries a 1/4 in NPT port, a fine 5 um filter element (code W), a differential-pressure drain in the PC bowl, a round pressure gauge reading in psi, a built-in reverse/check valve (code K), and a mounting bracket. The standard regulator covers 0.15-0.9 MPa (20-130 psi) with this drain type, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and with choices of drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, thread (PT standard; G and NPT are order options), bracket and check valve. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Feeding clean, regulated air to the tool-change and clamping circuits of a CNC machining centre, with the 5 um element and check valve protecting the valves downstream.
Conditioning the supply to pneumatic cylinders and diverters on a carton sealing and conveying line, holding a steady setpoint as line demand fluctuates.
Supplying filtered, regulated air to bench-top lab equipment and analytical instruments where finer 5 um filtration and a stable pressure are part of the setup.
Start with the port step: size 200 with a 1/4 in NPT port suits lighter duty lines; step up to sizes 300, 400 or 600 as your air demand grows. Choose the drain to match the installation: differential-pressure (this unit) drains on pressure drop, automatic suits unattended duty, and manual suits supervised points. Pick the filter grade for the task: 40 um is the standard element, 5 um (code W, as fitted here) for cleaner air downstream. Select the gauge style and scale (square embedded or round external; MPa, psi or bar), the thread family (PT standard, G or NPT to order), and whether a bracket or check valve is needed. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing against the datasheet before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow 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 number here. Tell us your line pressure, setpoint and air demand and we will confirm the flow figures from the datasheet for this exact configuration before you order.
The W in the code specifies the optional 5 um filter element instead of the 40 um standard, for cleaner air to sensitive downstream equipment. The K specifies a reverse/check valve, which holds the downstream setpoint if the upstream supply is lost. Both are decodable order options on the GFR series.
