The AirTAC GFR200C08LJC3WTK 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 GFR200C08LJC3WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds the downstream pressure at a set point, in one body. This 200-size unit is ported 1/4 in NPT and carries the L code, meaning it is the low-pressure regulator type, intended for circuits that run at reduced settings. The W code specifies the 5 um filtration element in place of the 40 um standard, condensate is discharged through the differential-pressure drain, and a round gauge with a bar scale is fitted so the set point can be read locally. A reverse/check valve (K) is fitted and no mounting bracket is supplied (J). The 200-size bowl is polycarbonate.
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 can be ordered with manual or automatic drain, 40 um or 5 um filtration, square or round gauges with MPa, psi or bar scales, G or NPT threads, and with or without a bracket. Flow for GFR units is published as curves rather than a single rated figure, so ask us to confirm the datasheet 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.

Conditions the air feeding spray guns in a finishing booth: the 5 um element strips water and particles before the gun while the low-pressure regulator holds a gentle, repeatable setting suited to fine finish work.
Prepares the supply to small cylinders and grippers on a packaging conveyor; the differential-pressure drain discharges collected condensate in service, so the bowl does not need hand-draining every shift.
Serves pneumatic control panels on laboratory and process analyser skids, where the fitted round bar gauge gives a local pressure reading and the built-in reverse/check valve backs the downstream circuit.
Size the unit by port and expected air demand: this 200-size version covers 1/4 in, while the 300, 400 and 600 sizes step up in port and capacity - match the step to the circuit's air consumption rather than to the fitting alone. The choices decodable in this code are: 5 um filtration (W) instead of the 40 um standard; differential-pressure drain (the family default, with automatic and manual available across GFR); low-pressure regulator type (L); round gauge on a bar scale (C3); NPT thread (T), where PT is the catalogue standard and G is also offered; and no mounting bracket (J). Because flow is published as curves and not as a single rating, send us your application conditions 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 GFR flow as curves, not as a single rated figure, so we do not quote a number here. Tell us your inlet pressure, set pressure and expected air consumption, and we will confirm the flow from the datasheet for this exact model before you order.
It marks the low-pressure regulator type. This variant is intended for circuits that hold a reduced downstream setting rather than the standard range; the exact setting range for the low-pressure type is not published in the catalogue, so check with us and we will confirm it against the datasheet.
