The AirTAC GFR600C25ALNT AirTAC Low-Pressure Filter Regulator 1in 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 GFR600C25ALNT is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, sized for 1 in (NPT) connections. This configuration is the low-pressure regulator type with an automatic drain, a 40 um standard filter element and no gauge fitted. The size-600 bowl is aluminium alloy, and the mounting bracket is included. Because the regulator is the low-pressure type, the exact adjustment range is not published in the material we hold, so confirm it against your set pressure before ordering.
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, and is configurable by drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um with code W), gauge and scale, thread (PT standard, with G and NPT as order options) and bracket. Flow is published as curves rather than a single rated figure, so we confirm datasheet and flow 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.

On a food and beverage canning line, gate and clamp actuators often run from a low-pressure regulated branch. A 1 in filter regulator conditions the plant air feeding that branch, with automatic drain keeping condensate off the valves between washdowns.
Stopper and release cylinders along a bottling conveyor need clean, regulated air at modest pressures. This low-pressure-type filter regulator at the 1 in branch supply filters water and particulate and holds the branch setpoint without a gauge cluttering the panel.
Looms and fabric-handling equipment use low-pressure air for thread tensioning, doffing arms and pneumatic guides. A 1 in NPT filter regulator with automatic drain conditions the supply to those circuits, and the included bracket simplifies mounting beside the machine's valve block.
Work from the decodable choices: step up through sizes 200/300/400/600 and their port sizes (here 1 in NPT) as your air demand grows - flow is published as curves, not a single rating, so ask us to confirm sizing against your consumption before ordering. Choose the drain to suit service: automatic (this unit) drains without attention, manual needs operator action, differential-pressure is the catalogue default. Filter grade is 40 um standard; 5 um (code W) suits finer downstream needs. Gauge is not fitted on this code (N) - a gauge can be specified on other codes, with square or round style and MPa, psi or bar scale. Thread is NPT here; PT is the standard and G is also a catalogue option. Bracket is included.
If your line runs at low regulated pressure, the low-pressure regulator type (code L) is the relevant variant; the exact adjustment range is not published, so confirm it with us. We will check the flow curves against your application before you commit.
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 GFR600 as curves, not as a single rated figure, so we do not quote a number here. Tell us your line's air consumption and working pressure and we will confirm the flow from the datasheet curves for this exact 1 in NPT configuration before you order.
The A in this code means the bowl drains condensate automatically, which suits unattended or hard-to-reach installations. If your maintenance routine prefers scheduled manual draining, the same GFR600 body is available with a manual-drain code - note that the drain type also affects the regulator adjustment range, so ask us to confirm the right variant for your set pressure.
