The AirTAC GFR20008LC2WTK 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 GFR20008LC2WTK is a size-200 filter regulator: it removes water and particulate down to 5 um and regulates downstream pressure in a single body, so one component does the job of a filter and a regulator. This unit is the low-pressure type, threaded NPT1/4 (1/4 in), with a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. A round gauge scaled in psi is fitted, a reverse/check valve is built in to hold downstream pressure when the supply is lost, and a mounting bracket is included. The polycarbonate bowl lets you see the condensate level at a glance.
This is a genuine AirTAC part for compressed air only, rated to a maximum inlet pressure of 1.0 MPa (145 psi) and a temperature range of -5 to 70 C (non-freezing). The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and is offered with manual, automatic or differential-pressure drains, 40 um or 5 um filtration, MPa/psi/bar gauge scales, and PT, G or NPT threads. 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. 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.

On an assembly fixture where workpieces must be held gently, the low-pressure regulator sets a reduced clamping force while the 5 um element keeps moisture and fine particles out of the clamp cylinders. The check valve holds the clamp if the shop air drops.
At a packaging line's individual drop, this unit filters and regulates the air feeding seal bars and small actuators, with the differential-pressure drain clearing condensate automatically through repeated shift cycles.
For benchtop analytical or testing instruments running on shop air, the 5 um grade polishes the supply before it reaches sensitive pneumatic valves, and the psi-scaled gauge gives operators a familiar local pressure readout.
Size and port are the first choice: the 200 frame with its 1/4 in port suits lighter air demand, while 300, 400 and 600 step up in port size and flow capacity - match the step to the flow your line actually needs. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering. Other decodable choices: drain type (differential-pressure as here, automatic, or manual), filter grade (40 um standard or 5 um as fitted here for finer protection), gauge scale (MPa, psi or bar), thread (PT is the standard; G and NPT are ordered options, as with this NPT unit), and bracket. The low-pressure type (code L) is selected when the circuit works below the standard regulator band; its exact adjustment range is not published, so confirm it with us. Note that the reverse/check valve (code K) holds downstream pressure on supply loss - omit it if you want free venting.
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 this family as performance curves, not as a single rated number, so we do not quote a figure here. Tell us your line pressure and the air demand of your equipment and we will confirm the correct size from the datasheet on request before you order.
K means a reverse/check valve is fitted: it holds pressure downstream if the upstream supply is interrupted. The L code marks the low-pressure regulator type, chosen for circuits that work below the standard adjustment band; its exact range is not published, so confirm it with us. This unit also carries W (5 um filtration instead of the 40 um standard), C2 (round gauge, psi scale) and T (NPT thread instead of the PT standard).
