The AirTAC GFR600C25LF2GK 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 GFR600C25LF2GK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This 600-size unit is built around a G1 (1 in) port with G (BSPP) thread, a differential-pressure drain that bleeds condensate as flow passes the element, and the standard 40 um filter element. Regulation is the low-pressure type, and the embedded square gauge reads in psi. A reverse/check valve is fitted, a mounting bracket is included, and the 600-size bowl is aluminium alloy. 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, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, psi, MPa or bar gauge scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and datasheet figures 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.

Feeding filtered, pressure-controlled air to spray-booth and coating-line circuits, where the low-pressure regulation band and 40 um element keep atomising air clean and steady at a 1 in mains connection.
A point-of-use filter regulator ahead of gripper and clamp cylinders on a bottling or cartoning conveyor, with the fitted check valve holding the downstream side if upstream supply dips.
A bench-mounted supply for leak and functional testing of pneumatic assemblies, where the psi square gauge, aluminium alloy bowl and included bracket suit a panel-built rig running on 1 in plant air.
Work from the port step first: this is the 600 size with a G1 (1 in) G-thread port, the largest in the GFR range, so match it where your circuit uses 1 in connections; the 200/300/400 sizes step down through 1/8 to 3/4 in. Drain type is a real choice: differential-pressure (this unit, blank code), automatic (A) or manual (M). Filtration is the 40 um standard element here; specify code W for the 5 um element. The gauge is the embedded square type reading psi (code 2); MPa (1) and bar (3) scales and an external round gauge are options. This is the low-pressure type (L); the blank-code standard type is the alternative. Threads come as PT (standard), G or NPT, and the bracket is included unless J is ordered. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and the full datasheet figures for this exact model on request.
K means a reverse/check valve is fitted, so air cannot flow back through the unit toward the filter bowl. The rest of the code decodes as: 600 size, 1 in port, G thread, low-pressure type, square psi gauge, differential-pressure drain, 40 um element, bracket included.
