The AirTAC GFR20008LC2WK AirTAC Filter Regulator PT1/4, 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 GFR20008LC2WK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation in a single body. This 200-size unit is ported PT1/4 (1/4 in, PT thread standard, with G and NPT available as order options) and carries the fine 5 um filter element (code W) instead of the standard 40 um, so it suits air lines feeding sensitive downstream components. It is the low-pressure type (code L) for circuits running below standard regulator settings, and its exact adjustment range is not published in the catalogue - we confirm it on request. A round pressure gauge with psi scale (code C2) is fitted, a reverse/check valve (code K) is included, and the differential-pressure drain bleeds accumulated condensate automatically as flow passes through. The polycarbonate bowl is transparent for visual level checks, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, standard or low-pressure regulation, gauge scale options, and an optional reverse/check valve. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm flow and full datasheet figures against 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 clean, low-pressure regulated air to laboratory analysers and sampling systems, where the 5 um element protects sensitive pneumatic internals and the check valve holds settings during supply fluctuations.
Regulates and filters air to sealing bars and small cylinders on cartoning and wrapping lines, with the psi gauge giving operators a direct local pressure readout at the machine.
Supplies filtered, regulated air to workholding clamps on machining fixtures, where the reverse/check valve maintains clamp pressure if the main supply drops mid-cycle.
Start with the port step: this unit is the 200 size with a PT1/4 connection, the smallest GFR frame - match it to your line size and required air demand, and step up to 300/400/600 where flow demand is higher. The 5 um element (code W) is the right choice ahead of precision valves, instruments or paint equipment; choose the standard 40 um element for general shop-air protection. The low-pressure type (code L) is intended for circuits regulated below standard settings - ask us to confirm the exact adjustment range before ordering. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the other catalogue options. The reverse/check valve holds downstream pressure if upstream supply dips - valuable for clamping or holding circuits. PT thread is standard on this model; G (BSPP) and NPT are order options. Bracket included. Flow is published as curves, not a single rating, so send us your application details 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. 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 no one-number rating exists for us to quote. Send us your line pressure, downstream demand and application details and we will confirm the flow figures from the datasheet against your requirement before you order.
The W in the code GFR20008LC2WK selects the fine 5 um filter element instead of the 40 um standard, for lines feeding sensitive components, and the K selects a reverse/check valve that holds downstream pressure during upstream supply dips. Both are catalogue options on the GFR family; the 40 um element, or a version without the check valve, can be ordered instead if your circuit does not need them.
