The AirTAC GFR600C25ALJC2TK 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 AirTAC GFR600C25ALJC2TK is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size 600 unit is built around a 1 in NPT port, with an automatic drain that clears collected condensate from the aluminium alloy bowl without manual attention, a 40 um standard filter element, and a low-pressure regulator type. A round pressure gauge scaled in psi is fitted, and a reverse (check) valve is built in; no mounting bracket is included with this code.
It is a genuine AirTAC part, covering the GFR size range from 200 to 600 with port sizes from 1/8 to 1 in, plus drain, filter-grade, gauge and thread options to order. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, so ask us to confirm datasheet and sizing figures for your application on request.

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.

Conditioning the compressed air feeding a bottling line's main distribution header: water and pipe scale are drained out of the aluminium bowl automatically, while the low-pressure regulator holds a gentle, stable supply pressure to the filling and capping actuators.
Feeding the stopper and diverter cylinders along a packaging conveyor, where the 1 in NPT port serves a high-volume branch and the automatic drain keeps condensate out of the gate valves during multi-shift running.
Conditioning air to big quarter-turn actuator valves on a water treatment plant's process lines, with the round psi gauge giving operators a local reading and the built-in check valve holding the set pressure if upstream supply dips.
The real choices in this family are decodable from the code. Size 200/300/400/600 sets the port and the volume of air the unit passes, so step up to size 600 (1 in port on this unit) when the line feeds high-demand actuators. Drain type is differential-pressure by default, with automatic (this unit) or manual as options. The filter element is 40 um standard or 5 um with code W. The gauge can be the embedded square type or an external round gauge scaled in MPa, psi or bar; this code carries a round psi gauge. Thread is PT as standard, with G and NPT as order options, and a bracket can be included or omitted. Flow is published as curves, not a single rating, so please ask us to confirm sizing against your application 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote one number. Send us your line pressure, downstream demand and allowable pressure drop, and we will confirm the sizing from the datasheet on request.
This code carries drain type A: an automatic drain that discharges collected condensate from the bowl without manual attention. The family also offers the differential-pressure drain (default) and a manual drain (code M); automatic suits points that are hard to reach or run unattended. Note that this is the low-pressure regulator type, whose set range is not published in the standard table, so confirm the range with us before ordering.
