The AirTAC GFR600C25ALJF3T AirTAC Filter Regulator 1 in NPT 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 GFR600C25ALJF3T is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 1 in NPT port, a 40 um filter element, an automatic drain that ejects collected condensate without manual attention, and a low-pressure regulator type. An embedded square gauge with a bar scale is fitted so the set pressure is visible at the unit, 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. The unit is supplied without a mounting bracket and without a reverse/check valve.
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, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, standard or low-pressure regulator types, square or square/round gauge options with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, 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 drop to a spray-booth air line, the unit strips water and particulate that would ruin finish quality and holds a steady, low preset pressure to the spray guns via the low-pressure regulator, with the bar-scale gauge letting painters verify the setting at a glance.
Mounted on the air supply to carton-closing and taping cylinders on a packaging conveyor, the unit removes pipeline condensate before it reaches the valves and keeps the cylinder pressure at the gentle, consistent setting the low-pressure regulator type is chosen for.
Fitted on the compressed-air feed to lab automation benches and pneumatic test rigs, the unit cleans the shop air supply and regulates it down to the low working pressures that sensitive actuators and instruments need, with the automatic drain keeping the bowl clear between runs.
Step up through the GFR sizes (200, 300, 400, 600) and their port sizes (1/8 in to 1 in) according to the air demand of the line; this 600 unit with a 1 in NPT port sits at the top of the range for high-flow mains. Choose the drain to suit access: automatic (this unit) for unattended condensate rejection, manual for supervised draining, or the differential-pressure default. Choose the 40 um standard element for general air preparation, or order the W variant for 5 um fine filtration. Gauge scale is selectable (MPa, psi or bar); this unit carries the square gauge with a bar scale. Thread is selectable: PT is the standard, with G (BSPP) and NPT (this unit) as order options. Bracket: this code is supplied without one, and a bracket can be ordered. Because flow is published as curves and not as a single rated figure, send us your application details and we will confirm sizing against the datasheet before you order.
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 performance curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your line pressure and air demand and we will confirm the sizing from the datasheet for this 600-size, 1 in NPT unit before you order.
The A in the code GFR600C25ALJF3T specifies an automatic drain, which ejects collected condensate from the aluminium bowl without anyone having to open it - useful for unattended or high-humidity installations. The GFR family is also available with a manual drain or the differential-pressure drain as the default, so a different drain type can be selected in the model code when ordering.
