The AirTAC GFR600C25LJC1WT 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 GFR600C25LJC1WT is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size-600 configuration carries a 1 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain on the bowl, and a round pressure gauge reading in MPa. The regulator is the low-pressure type, the size-600 bowl is aluminium alloy, and no mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with matching ports, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulation, gauge and thread options, and optional brackets. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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.

Point-of-use conditioning for a carton-forming or wrapping machine: the 5 um element strips water and fine particles before the low-pressure regulator feeds actuator circuits that run below standard header pressure.
Conditioning the air feeding stopper gates and pusher cylinders on a bottling conveyor, where the 1 in NPT port suits a main header take-off and the round MPa gauge lets operators check the set pressure at a glance.
Supplying clean, regulated low-pressure air to a laboratory or QA test bench, with the differential-pressure drain handling condensate in the aluminium alloy bowl between runs.
Size and port step up together across the GFR range - 200, 300, 400 and 600 - so choose the size whose flow curve covers your demand rather than sizing on the port alone; we can check the curve against your application. Drain choice is differential-pressure (fitted here), automatic or manual. Filter grade is 40 um standard or 5 um (code W), which this model carries. Gauges are embedded square as standard with an optional external round gauge in MPa, psi or bar scales; this unit has the round MPa gauge. Threads come as PT (the series standard), G (BSPP) or NPT - this model is NPT. Brackets are optional; this configuration comes without one. Because flow is published as curves and not a single rating, ask us to confirm sizing 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. Tell us your application and we will confirm the relevant curve and sizing from the datasheet on request.
L marks the low-pressure regulator type; the exact adjustment range for this variant is not published in the material we hold, so we confirm it on request. T is the thread: this model has a 1 in NPT port. PT is the standard thread for the series, with G (BSPP) and NPT available as order options.
