The AirTAC GFR600C25LJC2WK AirTAC Filter Regulator 1 in PT 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 GFR600C25LJC2WK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built for a 1 in PT port, filters to 5 um (the fine grade, code W, rather than the 40 um standard element), and is the low-pressure regulator type for reduced setpoints. It carries a differential-pressure drain, a round external gauge reading in psi, and a built-in reverse/check valve, and it is supplied without a mounting bracket. The size-600 bowl is aluminium alloy. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
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, and each size can be ordered with your choice of drain type, filter grade, gauge style and scale, thread (PT standard, G and NPT as options), bracket and check valve. Flow is published in the catalogue as curves rather than a single rated figure, so ask us and we will confirm the sizing and 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. 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.

Pneumatic clamps and positioning fixtures that must hold parts gently run on air regulated well below line pressure. This filter regulator cleans the supply to 5 um, holds the reduced setpoint, and its check valve holds the circuit against backflow at the fixture drop.
Pilot plants and lab-scale process skids feed transducers, indicator controllers and small actuators that are sensitive to both particles and pressure overshoot. A 5 um element plus low-pressure regulation and a psi-reading gauge suits these reduced-pressure instrument supplies.
Pushers, diverters and gating cylinders on packaging conveyors often run best at reduced pressure to avoid product damage. This 1 in filter regulator conditions and steps down the supply at the conveyor drop, with the differential-pressure drain handling condensate automatically.
Step up or down through the GFR sizes (200/300/400/600) and their ports (1/8 in to 1 in) to match the air demand of the line; larger sizes carry larger ports and higher flow capacity, with the exact flow confirmed from the curve data on request. Choose the drain: differential-pressure (this unit, drains on the pressure drop across the element), automatic, or manual. Choose the filter grade: 40 um standard or 5 um (code W, fitted here) where finer particulate protection is needed. Select the gauge style and scale - embedded square or external round, in MPa, psi or bar (this unit: round, psi) - and the thread: PT is the standard, with G (BSPP) and NPT as order options. Decide on a bracket and, where backflow protection matters, the reverse/check valve (fitted here).
Because catalogue flow is published as curves and not as a single rated number, send us your application details and we will confirm sizing against the datasheet before you order. The exact regulation range of the low-pressure type is also confirmed on request.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. 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 SCFM number. Send us your line conditions and required air demand and we will confirm the sizing from the datasheet curves on request before you order.
W is the fine filtration grade: a 5 um element instead of the 40 um standard element. Choose 5 um where downstream valves, cylinders or instruments need finer particulate protection; choose the 40 um standard grade where general water and coarse particle removal is enough. This unit is supplied with the 5 um grade.
