The AirTAC GFR200C08LF2WTK AirTAC Filter Regulator NPT1/4 Low-Pressure 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 GFR200C08LF2WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air down to 5 um and regulates downstream pressure in the same body. This size 200 unit is threaded NPT1/4 and is the low-pressure regulator type. It drains by differential pressure, the standard arrangement, and a metal bowl collects the separated condensate. A square pressure gauge with a psi scale is fitted, a reverse/check valve is built in, and the mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating 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 ports from 1/8 to 1 in, and each unit can be ordered with a different drain type, a 40 um or 5 um element, a gauge scale in MPa, psi or bar, and PT, G or NPT thread. Flow is published as curves rather than a single rating, so ask us to confirm the figures 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.

Feeding filtered, regulated low-pressure air to the pneumatic cylinders and directional valves that operate sealing jaws and product clamps on a packaging machine, with the 5 um element protecting the valve seats from particulate and condensate.
Supplying clean, regulated low-pressure air to analytical instruments and pneumatic sample-handling hardware, where the 5 um filtration grade and the fitted reverse/check valve help protect sensitive downstream components.
Regulating supply pressure to pneumatic clamps and swing cylinders on a machining or assembly fixture, with the built-in reverse/check valve blocking backflow toward the supply side of the circuit.
Size 200 with a 1/4 in port suits compact circuits; step up to 300, 400 or 600 when the line needs a larger port and more flow capacity - match the size to the air demand of the application rather than the pipe alone. This unit is the low-pressure regulator type; its exact adjustment range is not published in the catalogue, so confirm it with us against your set pressure. The 5 um element (code W) is the finer of the two grades - choose 40 um where coarser protection is enough. Drain is differential-pressure by default, with automatic (A) and manual (M) available as options. Thread here is NPT; PT is the standard and G (BSPP) is also an order option. Gauge scale is psi on this unit, with MPa and bar scales available. Flow is published as curves, not a single rating - send us your demand and we will confirm sizing 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, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the flow from the datasheet for this exact model before you order.
W is the filter-grade code: this unit carries the optional 5 um element instead of the 40 um standard. The finer grade suits circuits with sensitive valves and instruments; choose 40 um where coarser protection is enough. Both grades are available across the GFR range.
