The AirTAC GFR600C25ALNTK AirTAC Filter Regulator 1 in 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 AirTAC GFR600C25ALNTK is a size 600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built around a 1 in NPT port for high-flow supply lines, an automatic drain that expels collected condensate without manual attention, and the standard 40 um filter element. The regulator is the low-pressure type, a reverse/check valve is fitted, and no gauge is supplied with this code. The size 600 bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of ports, drain types, a 5 um optional element (code W), gauge options and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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.

At a 1 in NPT connection this filter regulator sits on a main air drop feeding assembly-tool circuits, cleaning water and particulate from the plant supply and holding the reduced pressure the downstream tools were set up for, with the automatic drain handling condensate between shifts.
On a bottling or canning line, a single size 600 unit can feed the conveyor stoppers, pushers and gate cylinders from one point, filtering the compressed air and regulating it to the pressure the cylinder sizing assumed, while the automatic drain keeps moisture out of the valves.
On a chemical pilot-plant skid, instrument and actuator air taken from the utility header passes through this unit so the 40 um element strips water and pipe scale and the low-pressure regulator holds a gentle, stable supply pressure for the skid's air-operated valves.
Step up through sizes 200, 300, 400 and 600 as your port and air demand grow; this unit is already at the top of the range with its 1 in NPT connection. Choose the drain to match access: automatic (as here) for unattended duty, manual for periodic servicing, or the differential-pressure default. Filter grade is 40 um standard; specify code W for the 5 um element where finer particulate removal is needed. A gauge can be added at order stage, and PT is the standard thread with G and NPT as catalogue options. Note that the low-pressure regulator type has a different adjust range from the standard type and the exact figure is not published, so confirm it with us first.
Because flow is published as curves and not as a single rating, we cannot quote one number here. Send us your application details and we will confirm sizing against the datasheet curves 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 rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow and sizing from the datasheet curves on request before you order.
The A in the code selects the automatic drain: collected condensate is expelled from the aluminium alloy bowl without anyone opening it, which suits unattended or high-humidity installations. The family also offers a manual drain and a differential-pressure drain as alternative order codes if you prefer service-based or demand-based draining.
