The AirTAC GFR20008LJC2WT AirTAC Filter Regulator NPT1/4 Low-Pressure 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 GFR20008LJC2WT is a size-200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is a 1/4 in NPT ported unit of the low-pressure type, fitted with a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate as flow passes through, and an external round gauge reading in psi so the set pressure is visible at the wall of the unit. It is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including manual or automatic drains, a 40 um standard element, different gauge scales, G or NPT threads in addition to the PT standard, and a reverse/check valve. Flow is published as curves rather than a single rating, so we confirm the datasheet figures for 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.

Air-operated clamps and swing cylinders on machining fixtures often hold at modest set pressures. This low-pressure filter regulator sits at the drop to the fixture, cleaning the supply to 5 um and holding the clamp circuit at the set point shown on the round psi gauge.
Paint and coating guns need clean, dry air at a gentle, stable setting. The 5 um element keeps fine particulate out of the finish, the low-pressure type suits the gentle set points spray work demands, and the psi gauge lets the operator dial in and verify the setting.
Sorting fingers, pusher cylinders and gate actuators along a packaging line run continuously off a shared header. A filter regulator at each drop conditions the branch supply and lets the line crew set each station's pressure locally, with the differential drain handling condensate during production.
Start with the port and size: the 200 frame with a 1/4 in NPT port is the entry step of the GFR range, and the next sizes (300, 400, 600) step up both port and flow capacity - match the frame to the air demand of the circuit rather than oversizing by habit. This unit is the low-pressure type, chosen when the working set point sits well below the standard regulator's range; the exact adjustment window for the low-pressure version is not published in the sheet we work from, so ask us to confirm it before ordering. The 5 um element (code W) suits downstream equipment sensitive to fine particles; the 40 um standard element is the choice for general-purpose lines. The differential-pressure drain needs no operator attention but relies on flow to purge, so if the unit sits mostly idle, consider the automatic or manual drain variants. Gauge scale here is psi; MPa and bar scales are available. Thread is NPT on this code; PT is the catalogue standard and G (BSPP) is also an order option. Flow is published as curves, not a single rating - send us your application 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. 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 number, so we do not quote a figure here. Tell us your application and line pressure and we will confirm the flow and sizing against the datasheet on request before you order.
The W in the code GFR20008LJC2WT selects the optional 5 um filter grade. The 40 um element is the standard choice for general plant air, while 5 um suits downstream equipment such as spray guns, precision valves and instruments that are sensitive to fine particles. If you prefer the standard grade, order the same unit without the W.
