The AirTAC GFR600C25ALC2WGK AirTAC Filter Regulator G1 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 GFR600C25ALC2WGK is a size-600 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration is the low-pressure type (code L), so it is intended for circuits that run well below standard line pressure; its exact adjustment range is not published, so confirm the set pressure with us against the datasheet. It carries a G1 (1 in) female thread, a 5 um filter element (code W, finer than the 40 um standard), an automatic drain that bleeds collected condensate without manual attention, a round external pressure gauge scaled in psi, a reverse/check valve, and the included mounting bracket. At size 600 the bowl is aluminium alloy, and the maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in. Within the family you can choose drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge style and scale (MPa, psi or bar), thread (PT standard, with G and NPT as order options), and bracket or no-bracket versions. Flow 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.

Fixture clamps and swing cylinders on an assembly line that run at reduced set pressure get filtered, regulated air from one compact body, with the psi gauge letting operators verify the clamp circuit setting at a glance.
Bench test rigs and pilot-scale rigs that must not see full line pressure use the low-pressure type to hold a gentle, repeatable supply, while the 5 um element protects sensitive instruments and the check valve holds the setting if upstream air dips.
A 1 in main drop feeding a packaging or palletising machine gets bulk water and fine particulate stripped out ahead of valves and cylinders, and the automatic drain keeps condensate off the shop floor without daily bowl visits.
Start with the port step: size 600 with a G1 (1 in) thread sits at the top of the GFR range, so match it to the line size and the flow your circuit needs rather than upsizing on guesswork. Because this is the low-pressure type (L), verify that your working pressure falls in the low-pressure band and ask us for the exact adjustment range before ordering - the standard type's published range does not apply here. The 5 um element (W) suits downstream equipment sensitive to fine particles; the 40 um standard element is the choice where only bulk water and coarse dirt matter. The automatic drain (A) suits unattended or hard-to-reach installations; manual and differential-pressure drains are available elsewhere in the family. The round psi gauge (C2) gives a familiar external readout; square embedded gauges and MPa or bar scales are the alternatives. Thread is G (BSPP) here, with PT standard and NPT available to order, and the bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the curve data and correct size before you order.
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 family as performance curves, not as a single rated figure, so we do not quote a l/min or SCFM number here. Send us your line size and application and we will confirm the curve data from the datasheet so you can size the unit correctly before ordering.
The L code in GFR600C25ALC2WGK marks the low-pressure regulator variant, intended for circuits that run below standard line pressure. Its exact adjustment range is not published in the material we hold, so confirm your set pressure with us against the datasheet. The unit is read via the supplied round gauge scaled in psi, and the maximum inlet pressure remains 1.0 MPa (145 psi).
