The AirTAC GFR600C25ALJC2WG AirTAC Filter Regulator G1 (1 in) 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 GFR600C25ALJC2WG 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 around a G1 (1 in) port, a 5 um filter element for finer filtration than the standard 40 um grade, and an automatic drain that expels collected condensate from the bowl without manual attention. It is a low-pressure regulator type fitted with an external round gauge reading in psi, and it ships without a mounting bracket. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and is configurable by drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional), gauge style and scale (embedded square or external round; MPa, psi or bar), thread (PT standard, G and NPT as order options) and bracket. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding a carton-sealing and wrapping machine's air cylinders from a plant ring main: the 5 um element polishes the air before it reaches the valve stack, the regulator holds a steady low supply pressure to the actuators, and the automatic drain keeps condensate out of the bowl on a line that runs unattended across shifts.
Mounted at the drop from the main header to a pneumatic clamping fixture on a machining cell, the unit filters swarf-laden shop air down to 5 um and regulates the clamp circuit at the lower pressure the fixture was designed for, with the round psi gauge giving the setter a direct pressure readout at the point of use.
Supplying the air jets, guides and small actuators on a converting or textile machine where sensitive components need cleaner air than the standard 40 um grade delivers: the G1 (1 in) port matches the machine's main air inlet, the aluminium bowl suits the higher-flow size-600 position, and the automatic drain handles the condensate load from a long compressed-air run.
Start with the port and size step: GFR units step through sizes 200, 300, 400 and 600 with ports from 1/8 in up to 1 in, and the size you pick should follow the air consumption of the downstream circuit rather than the pipe alone. This unit is already at the top of the range: size 600 with a G1 (1 in) port. Drain type is a real operating choice: differential-pressure drain is the default, automatic drain (as fitted here) empties the bowl unattended, and manual drain suits installations where someone checks the bowl routinely. Filter grade is 40 um standard or 5 um (code W) where finer particulate removal is needed - this unit carries the 5 um element. Gauge options are the embedded square gauge or an external round gauge, with MPa, psi or bar scales; this configuration has a round psi gauge. Thread is PT as standard with G and NPT available as order options, and a bracket is optional (this unit has none).
One honest routing note: flow for the GFR series is published as curves, not as a single rated number, so we cannot quote a rated flow figure here. Send us your application details and we will confirm sizing against the datasheet curves before you order. The exact regulation range of this low-pressure type is not published in the material we hold; we will confirm it 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 for this unit. Send us your application - the air consumption of the downstream equipment and your supply pressure - and we will confirm the sizing against the datasheet curves on request before you order.
The W in the code sets the 5 um filter grade, one step finer than the 40 um standard element, for circuits that need cleaner air. The A sets an automatic drain, which expels collected condensate from the bowl by itself instead of waiting for a manual or differential-pressure drain. The L sets the low-pressure regulator type, intended for circuits regulated below the standard range; the exact regulation range for this type is not published in our current material, so we confirm it on request. The unit also carries a round gauge reading in psi, uses a G1 (1 in) port with G thread, and has no mounting bracket.
