The AirTAC GFR600C25ALJF1WTK AirTAC Filter Regulator NPT1 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 GFR600C25ALJF1WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit has a 1 in NPT port, a 5 um filter element (code W), an automatic drain and an aluminium alloy bowl. The regulator is the low-pressure type (code L), and this configuration carries the embedded square gauge with MPa scale plus a reverse (check) valve; no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working 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 ports from 1/8 to 1 in, and options include manual or differential-pressure drains, the 40 um standard element, gauge scales in MPa, psi or bar, and G (BSPP) or NPT threads in place of the PT standard. AirTAC publishes flow for this series as curves rather than a single rated figure, so ask us and we will confirm the flow and datasheet figures for your application before you order.

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 air preparation for clamp cylinders on a machining fixture: the 5 um element protects directional valves from particulate and the automatic drain handles condensate in an unattended cell, while the low-pressure regulator sets the clamp circuit locally.
A filter regulator ahead of the actuators on a carton-forming or wrapping line: the 1 in NPT port matches the main air drop, the automatic drain keeps the metal bowl clear without operator attention, and the square MPa gauge gives a local set-point reading.
Bench and pilot rigs that need clean air regulated at low set pressures: the low-pressure type (L) suits the circuit, the embedded square gauge reads the setting in MPa, and the fitted reverse (check) valve is built into this configuration.
Size and port set the air capacity: this is the largest GFR size (600) with a 1 in NPT port, so match it to your piping and demand - we can check the published curve against your application. Choose the drain to suit access: automatic (this unit, code A) for unattended bowls, manual where an operator drains on schedule, or the differential-pressure default. Filter grade is 40 um standard or 5 um (code W, as here) for finer protection of downstream components. Gauges are embedded square as standard, with optional external round gauges in MPa, psi or bar scales. The low-pressure type (L) is intended for circuits set below the standard type's range; the exact adjustment range for this variant is not published, so confirm it with us before ordering. Threads are PT as standard with G (BSPP) and NPT as order options, and brackets are optional (this configuration has none).
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 rather than a single rated figure, so we do not quote a number here. Send us your line pressure, set pressure and air demand, and we will confirm the flow and datasheet figures for this exact model on request.
Code L marks the low-pressure regulator variant, intended for circuits set below the standard type's range. The exact adjustment range for this variant is not published in our data, so confirm it with us before ordering. Everything else decodes normally: 1 in NPT port, 5 um element, automatic drain, aluminium alloy bowl, square MPa gauge and a fitted reverse (check) valve.
