The AirTAC GFR600C25ALJC2T 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 GFR600C25ALJC2T is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This 600-size unit is built around a 1 in NPT port, so it suits the main air line of a large installation rather than a branch drop. It is the low-pressure type, intended where the working setpoint sits well below the standard range, and it carries the standard 40 um filtration element. The automatic drain bleeds collected condensate from the bowl without anyone opening it, which matters on lines that run unattended. The bowl at size 600 is aluminium alloy, the downstream pressure is shown on a round external gauge scaled in psi, and no mounting bracket is fitted. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with a choice of PT, G or NPT thread, differential-pressure, automatic or manual drains, a 40 um standard or 5 um (W) element, standard or low-pressure regulation, gauge and scale options, and bracket choices. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeds filtered, pressure-set air to spray guns and air-assisted applicators in a refinish booth, where the low-pressure type regulator holds a gentle, stable setpoint and the automatic drain keeps condensate out of the finish.
Installed at the head of a cartoning or shrink-wrap line to clean the supply and hold a fixed pressure on clamp and sealing cylinders, with the 1 in port carrying the whole line and the auto drain handling condensate between shifts.
Placed on the main air service feeding looms and winding heads, filtering water and lint-laden particulate from the plant supply and regulating it to the level the machines' air jets and cylinders were set up for.
Work size and port first: the G-series steps through 200, 300, 400 and 600, and this unit is the largest, with a 1 in NPT port - match the step to the flow your line needs, then confirm it against the published curves with us. Next, drain type: automatic (this unit) suits unattended or hard-to-reach installations; manual suits lines someone walks daily; differential-pressure is the default. Filter grade is 40 um standard here; choose the 5 um (W) variant only where downstream equipment demands finer filtration. Gauge options are the embedded square type or an external round gauge, with MPa, psi or bar scales - this configuration has a round gauge in psi. Thread is NPT here; PT is the standard and G is also a catalogue option. Brackets are optional on GFR, and this code specifies no bracket. Because flow is published as curves and not a single rating, send us your application and we will confirm sizing 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 flow for the GFR series as curves, not as a single rated number, so we do not quote a rated flow, Cv or SCFM figure. Send us your line pressure, setpoint and the equipment you are feeding, and we will confirm the datasheet curve and sizing for your application on request.
The automatic drain on this unit ejects collected condensate from the bowl on its own, so no one has to open a valve - useful for unattended lines or bowls mounted out of reach. The manual option drains only when operated by hand, and the differential-pressure drain (the series default) bleeds when the pressure differential across the element rises. This code is the automatic type.
