The AirTAC GFR600C25ALF2GK AirTAC 1 in Filter Regulator, 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 GFR600C25ALF2GK is a GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This 600-size unit is fitted with a G1 (1 in) female thread, an automatic drain that expels collected condensate without manual attention, and the standard 40 um filter element (a 5 um element is available as code W). The regulator is the low-pressure type, and the embedded square gauge is supplied with a psi scale (MPa and bar scales are catalogue options). A reverse/check valve is fitted, the mounting bracket is included, and the metal bowl on this 600 size is aluminium alloy. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating 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 port sizes from 1/8 in to 1 in, and options include manual or differential-pressure drains, the 5 um filter grade, alternative gauge scales and NPT or G threads in place of the PT standard. Flow is published by AirTAC as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Installed at the supply point of a pneumatic press circuit, this unit filters water and pipe scale from the shop air and holds the reduced working pressure the press cylinder and its control valves were set up for, with the automatic drain keeping condensate off the circuit during long production runs.
On a bottling or canning line, this 1 in filter regulator feeds the conveyor stops, pushers and gripper cylinders, removing moisture and particles that would score seals while the low-pressure regulator holds the gentle, stable pressure those handling actuators need.
Fitted on the air supply to textile machinery, the unit conditions the incoming compressed air before it reaches the machine's low-pressure circuits and jets, with the 40 um element catching particulates and the automatic drain clearing accumulated water without operator intervention.
Start with the size and port: 600 is the largest G-series step, and this unit carries a 1 in port, so match it against the pipe diameter and the air demand of the circuit it feeds. Because flow is published as curves rather than one rated number, ask us to confirm sizing against your application before ordering. Next, choose the drain: this unit has the automatic drain (code A), which suits unattended installations; manual and differential-pressure drains are the other catalogue choices. The filter grade here is the standard 40 um element - specify code W if the downstream equipment needs 5 um filtration. The regulator in this code is the low-pressure type (code L); the exact adjustment range for the low-pressure type is not published in the catalogue, so confirm it with us. The gauge is the embedded square type with a psi scale; MPa and bar scales and an external round gauge are options. Thread is G (BSPP) here; PT is the standard thread and G and NPT are options to order. A mounting bracket is included with this unit.
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. Tell us your line pressure, downstream demand and port size, and we will confirm the flow and sizing figures from the datasheet on request before you order.
The L code marks the low-pressure regulator type, intended for circuits that run at reduced working pressures; the exact adjustment range for the low-pressure type is not published in the catalogue, so confirm it with us. The A code is the automatic drain: collected condensate is discharged from the metal bowl without manual attention, unlike the manual (M) and differential-pressure (blank) drain options.
