The AirTAC GFR600C25ALJC1T AirTAC Filter Regulator NPT1 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 GFR600C25ALJC1T is a filter regulator: water and particulate filtration plus pressure regulation combined in one body. This size 600 unit is built around 1 in NPT ports and carries an automatic drain, a 40 um filter element and an aluminium alloy bowl. The regulator is the low-pressure type, a round pressure gauge with an MPa scale is fitted, no mounting bracket is included, and the unit is rated for a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
It is a genuine AirTAC part from the GFR range, which spans sizes 200 to 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application.

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.

Feeds filtered, regulated low-pressure air to the pneumatic clamps and swing cylinders on a machining fixture, keeping condensate and swarf-carried water out of the clamp valves.
Conditions the air feeding carton sealers, case erectors and bagging heads on a packaging line, with the automatic drain clearing bowl condensate through long production shifts.
Sits on the take-off to a low-pressure atomising or coating station, filtering the supply and holding the regulator setting the spray equipment was commissioned at.
Start from the port step: size 600 with a 1 in port is the largest in the GFR line, so step down to 300 or 400 only when the pipe run and the air demand at the machine allow it - we can check the flow curves against your consumption before you order. Choose the drain to match access: automatic drains the bowl without attention, manual needs an operator, and the differential-pressure default drains only when the pressure drop calls for it. This unit is the low-pressure regulator type, so confirm its adjustment range against your set pressure before ordering.
Filter grade is 40 um as standard here; the W variant gives the 5 um grade where finer filtration is needed. The round MPa gauge is fitted, and psi or bar scales are available as alternatives. Thread follows the trailing code letter: PT is the standard, with G and NPT as catalogue options - this unit is NPT. A bracket can be ordered where the J code in this model omits it.
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 number here. Send us your line pressure and air consumption and we will confirm the sizing from the datasheet on request.
The L in the code selects the low-pressure regulator version rather than the standard one. Standard GFR units with an automatic drain adjust over 0.15-0.9 MPa (20-130 psi); the exact range of this low-pressure type is not published, so we confirm it from the datasheet on request.
