The AirTAC AirTAC GFR200C08LJC2GK Filter Regulator G1/4 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 AirTAC GFR200C08LJC2GK is a size-200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the low-pressure type, built for circuits that run below standard line pressure, with a G1/4 (1/4 in) G-thread port, a 40 um standard filter element and a differential-pressure drain that bleeds collected condensate automatically as the pressure differential rises. It ships with a round psi-scale gauge fitted and a reverse/check valve installed, and mounts without a bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing); the bowl on this size is polycarbonate (PC).
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 (code W) filtration, differential-pressure, automatic or manual drains, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. 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. 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.

A fixture-clamping circuit that runs below standard shop pressure needs filtered air and gentle regulation at the drop. This low-pressure GFR at the G1/4 takeoff cleans the supply, holds the set pressure and its check valve holds the circuit against upstream loss.
Packaging machines with small-bore cylinders and air jets take 1/4 in feeds. A size-200 filter regulator at each drop removes condensate and particles, sets the working pressure with a psi-scale gauge in view, and the differential-pressure drain keeps moisture moving out with the flow.
A machining cell that uses low-pressure air for chip blow-off and part grippers benefits from one body doing both jobs: 40 um filtration protects the nozzles and valves, the low-pressure regulator sets the safe working pressure, and the round psi gauge lets an operator verify the setting at a glance.
Start with the port step: this unit is size 200 with a G1/4 (1/4 in) G-thread connection; larger sizes (300/400/600) carry bigger ports and higher flow capacity, so step up if your line needs more air. Choose the drain to match access: differential-pressure (this unit) drains itself with flow, automatic drains on a timer-free cycle, and manual drain suits stations someone visits regularly. Pick 40 um for general air prep or 5 um (code W) where finer protection matters. Gauges come as the embedded square type or an external round gauge in MPa, psi or bar scales - this unit carries a round psi gauge. Threads are PT as standard with G and NPT as order options, and brackets are optional.
One honest note on sizing: AirTAC publishes flow for this series as curves, not a single rated number, so we cannot quote a rated flow figure here. Send us your application details and we will confirm the flow curve and correct size against your requirement 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 number. Tell us your application - port size, upstream pressure and the air demand of your equipment - and we will confirm the flow curve from the datasheet and check the sizing with you before you order.
The L code marks the low-pressure regulator variant, intended for circuits that run below standard line pressure; the exact adjustment range for this variant is not published in the material we hold, so we will confirm it from the datasheet on request. This unit also differs from the standard build in its fittings: it comes with a round psi-scale gauge fitted, a reverse/check valve installed, and no mounting bracket.
