The AirTAC GFR60025ALC3T 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 PT1" ports, a automatic 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 GFR60025ALC3T is a size 600 G-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a 1 in NPT port, the largest port step in the G-series, so it sits on a main air drop or feeds a high-consumption machine section. It carries the standard 40 um filter element, an automatic drain that bleeds collected condensate from the bowl without anyone opening it, and the low-pressure regulator type for circuits that run well below standard line pressure. The fitted round gauge reads in bar, the bowl on this size 600 unit is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, thread options PT (standard), G and NPT, drain choices, 40 um or 5 um elements, and gauge variants. Rated flow is published only as curves rather than a single figure, so ask us to confirm sizing and datasheet 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 on the 1 in header feeding a production hall, it filters water and scale out of the plant air supply and holds the header pressure the downstream drops were designed around, with the automatic drain handling condensate on an unattended line.
Feeding the cylinder and actuator banks on a bottling or cartoning line, it keeps the air clean and the circuit pressure steady so indexing, clamping and ejection strokes repeat consistently through long production runs.
Used on web-handling, textile or food-processing equipment that runs its pneumatic section well below standard line pressure, where the low-pressure regulator type gives finer control in the working band and the bar gauge lets operators verify setpoints at a glance.
Choose by port and size step first: this unit is size 600 with a 1 in NPT port, the step for main lines and large machine supplies, while smaller sizes 200-400 cover 1/8 in to 3/4 in drops. The 40 um element is the standard grade for general plant air; if the circuit needs finer filtration, the W-coded 5 um element is the option to ask about. Drain choice matters in practice: this unit has an automatic drain, which suits unmanned or hard-to-reach installations, versus the manual-drain and differential-pressure-drain variants in the family. The low-pressure regulator type is the right pick where the circuit holds pressure well below standard line pressure; we confirm its exact adjustment range from the datasheet on request. The round bar gauge is fitted here, embedded square gauges with MPa/psi/bar scales are the alternative, and PT is the standard thread with G and NPT as order options. A mounting bracket is included.
Because rated flow is published as curves rather than a single number, 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 flow for the GFR family as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, downstream demand and acceptable pressure drop, and we will confirm the flow and sizing from the datasheet for this exact 1 in NPT, size 600 unit before you order.
The A in the code specifies an automatic drain: condensate collected in the aluminium bowl is discharged on its own, which suits installations that are not checked daily. The L specifies the low-pressure regulator type, intended for circuits that hold pressure well below standard line pressure; its exact adjustment range is not in the standard listing, so we confirm it from the datasheet on request. The C3 specifies the fitted round gauge reading in bar.
