The AirTAC GFR600C25ALJF2GK 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 GFR600C25ALJF2GK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single 600-size body with a G1 (1 in) port. This configuration carries a 40 um filter element, an automatic drain that expels collected condensate without manual attention, and a low-pressure regulator type for circuits that run at reduced supply pressure. The embedded square gauge reads in psi, a reverse-flow (check) valve is fitted, and the metal bowl on this 600 size is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). No mounting bracket is included with the J suffix.
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 is ordered with a choice of drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um with the W code), gauge scale (MPa, psi or bar), thread (PT standard, with G and NPT as order options) and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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.

At the wall drop feeding a packaging hall's pneumatic circuits, this G1 filter regulator removes water and pipe-scale from the main supply and holds a reduced, stable working pressure for the downstream machinery, with the automatic drain clearing condensate through the shift.
Grippers, pushers and diverters on a conveyor line behave best on clean, regulated air. This unit filters the supply to 40 um and regulates it to the pressure the cylinder circuit was designed around, while the check valve guards the setting against reverse flow.
Pneumatically actuated process valves need pilot air that is dry, particle-free and held at a steady pressure. This low-pressure-type filter regulator conditions the pilot supply on the skid, with the psi gauge giving operators a local reading at the valve assembly.
Start with the size and port: 600 is the largest G-series step, and here it carries a G1 (1 in) port, so match it against the pipe size and the air demand of the circuit. Since flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. Then set the decode options that matter: drain type (this unit is automatic; differential-pressure is the default and manual is also available), filter grade (40 um standard, 5 um with the W code for finer particulate), gauge scale (this unit's square gauge reads psi; MPa and bar scales exist), and thread (PT is the standard; G and NPT are catalogue options to order). Note that this is the low-pressure regulator type, so confirm the adjustment range for your set pressure with us rather than assuming the standard-range figures. The J suffix means no mounting bracket; bracketed versions are available.
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 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
The A in the code fits an automatic drain, which expels collected condensate from the bowl without anyone attending to it. The family also offers the differential-pressure drain (the default, which dumps when the pressure drop across the filter rises) and a manual drain (M) where an operator drains the bowl as part of a routine. Any of the three can be ordered on this 600-size filter regulator.
