The AirTAC GFR600C25ALJC2WGK 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 GFR600C25ALJC2WGK is a size-600 filter regulator: water and particulate removal plus pressure regulation combined in a single body, with a G1 (1 in) port. This configuration is built for finer air quality with a 5 um filter element (code W, against the 40 um standard), an automatic drain that clears collected condensate without manual attention, and the low-pressure regulator type (code L) for applications whose set points sit below the standard regulator's range. It is supplied with a round external gauge scaled in psi, a reverse/check valve already fitted, and no mounting bracket. At size 600 the bowl is aluminium alloy rather than polycarbonate. Maximum inlet pressure is 1.0 MPa (145 psi) and the working 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 can be ordered with manual, automatic or differential-pressure drains, 40 um or 5 um filtration, standard or low-pressure regulation, square or round gauges in MPa, psi or bar scales, a reverse/check valve, and PT, G or NPT threads. AirTAC publishes flow as curves rather than a single rated figure, so ask us to confirm flow and other datasheet values against 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.

On a bottling or canning line, air knives strip rinse water from containers before labeling. The low-pressure regulator holds a gentle, stable set point so labels are not disturbed, while the 5 um element and automatic drain keep the nozzle air dry and clean.
Dilute-phase powder conveying in a food or chemical plant runs on moderate, closely held air pressure. This unit filters the supply air to 5 um, regulates the header down to the conveying set point, and its automatic drain and check valve protect the line between batches.
Fine-bubble diffuser grids in a treatment basin need steady, low header pressure rather than high force. The G1 port suits the manifold supply, the low-pressure type matches the modest set point, and the automatic-drain aluminium bowl handles condensate from moist blower air.
Size and port are the first decision: this unit is size 600 with a G1 (1 in) port, the largest step in the GFR range, so match it to the pipe bore and the air demand of the circuit rather than upsizing on guesswork. Because flow is published as curves and not as a single rating, send us your application details and we will confirm sizing from the datasheet before you order. This unit is already specified as the low-pressure regulator type (L); if your set points fall in the standard range, the non-L variant is the usual choice, and we can confirm the exact low-pressure adjustment range on request.
The remaining decodable choices are all visible in the code: the 5 um element (W) where finer filtration matters, against the 40 um standard; the automatic drain (A) against manual or differential-pressure alternatives; the round psi gauge (C2) against the embedded square gauge and MPa or bar scales; the fitted reverse/check valve (K); the absence of a mounting bracket (J), which can be ordered separately; and the G thread, with PT as the standard and G or NPT available as order options.
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 this family as curves, not as a single rated number, so we do not quote a figure here. Send us your line pressure, set point and expected air consumption, and we will confirm from the datasheet curves whether this size-600, G1-port unit is correctly sized before you order.
The L in the code marks the low-pressure regulator variant, intended for set points below the standard type's range; its exact adjustment range is not published in the sheet we work from, so we will confirm it on request. The rest of the decode is unchanged: same G1 port, 5 um element, automatic drain, psi gauge and check valve as this configuration.
