The AirTAC GFR20008LJC2W AirTAC Filter Regulator PT1/4 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 GFR20008LJC2W is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This size-200 unit has a PT1/4 port, the 5 um filter element (code W) for finer filtration than the standard 40 um grade, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element is high enough. It is the low-pressure type, fitted with an external round gauge reading in psi, and supplied without a mounting bracket. The polycarbonate bowl suits the non-freezing -5 to 70 C operating range, and maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600, with port sizes from 1/8 to 1 inch, PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulation, gauge and bracket options, and a reverse/check valve option. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. 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 a CNC machining centre, the GFR20008LJC2W filters and regulates the 1/4-inch supply feeding clamping cylinders and tool-change actuators, with the 5 um element protecting sensitive valve spools and the psi gauge giving the operator a direct set-point readout.
On a packaging conveyor line, this filter regulator conditions the air feeding diverter gates, bag sealers and counting cylinders, keeping moisture and fine particulate out of the control valves while holding a stable low regulated pressure for consistent jaw and gate action.
On a lab or pilot-plant process skid, the low-pressure type GFR20008LJC2W supplies gentle, filtered regulated air to sample-handling actuators and purge lines, with the psi gauge allowing precise, repeatable setting at the bench.
Start with the port step: size 200 with a PT1/4 port is the entry point of the GFR range, and larger sizes (300, 400, 600) step up both port and flow capacity, so match the size to the air demand of the circuit rather than upsizing speculatively. This unit carries the 5 um element (W) - choose it where downstream valves and cylinders need finer protection than the standard 40 um grade. The differential-pressure drain is the default and suits most fixed installations; automatic or manual drains are the alternatives if condensate load or access dictates. The round psi gauge is fitted here; embedded square gauges and MPa or bar scales are the other catalogue choices. Thread is PT as standard, with G and NPT available to order, and brackets are optional. Because flow is published as curves rather than a single rating, 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. 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 rated flow, Cv or l/min number for this unit. Send us your application details and we will confirm the datasheet flow curve and check the sizing against your air demand before you order.
In the code GFR20008LJC2W, the W selects the 5 um filter element instead of the standard 40 um grade, giving finer protection for downstream equipment, and the C2 combination selects the external round gauge with a psi scale. The unit is also the low-pressure type and has a differential-pressure drain; 40 um filtration, MPa or bar gauge scales, and automatic or manual drains are available in other catalogue variants.
