The AirTAC GFR600C25ALJF2G 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 GFR600C25ALJF2G 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 with G thread, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filtration element, and a low-pressure regulator type. The embedded square gauge is fitted with a psi scale, and the size-600 bowl is aluminium alloy. No mounting bracket is included on this variant.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, with choices of drain type, 40 um or 5 um filtration, gauge scale, and thread form. Flow 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.

Filtering and regulating the compressed air feeding pneumatic actuators on loom and spinning lines, with automatic drain handling condensate in a humid mill environment.
Conditioning air for conveyor stopper and pusher cylinders on a bottling hall line, where the low-pressure regulator band and psi gauge suit the control station panel.
Supplying filtered, regulated air to impact wrench and nutrunner stations on a commercial vehicle assembly line, with the aluminium size-600 bowl standing up to high-demand tool circuits.
Start with the port step: this unit is size 600 with a G1 (1 in) port, the largest in the GFR range - step down to 200/300/400 if your line uses smaller ports, and match the size to the flow your circuit needs. Choose the drain to suit access: automatic (as here) suits installations that are not checked daily, manual suits attended stations, and differential-pressure is the default. Filtration is 40 um standard; specify the W code for 5 um where finer protection is needed. The fitted square gauge reads in psi; MPa and bar scales are available, and an external round gauge is optional. G thread is specified on this model; PT is the standard thread form with G and NPT as order options. Brackets are optional on GFR units, and this variant is ordered without one.
Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. The low-pressure regulator type on this model has no published adjustment range, so confirm the operating band with us as well.
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 rather than a single rated figure, so we do not quote a rated flow number. Tell us your line pressure and required downstream flow and we will confirm the sizing from the datasheet on request.
L marks the low-pressure regulator type; its exact adjustment range is not published in the catalogue, so confirm the operating band with us before ordering. The fitted square gauge on this unit reads in psi, and MPa or bar scales plus an external round gauge are available as options.
