The AirTAC GFR60025ALNTK AirTAC Filter Regulator 1 in NPT 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 GFR60025ALNTK is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air with the standard 40 um element, then regulates downstream pressure in the low-pressure type configuration. This unit is built in the largest G-series size with a 1 in NPT port, an automatic drain that ejects collected condensate without manual attention, an aluminium alloy bowl, and a reverse/check valve fitted. No gauge is supplied with this configuration.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application.

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.

| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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, regulated air to the clamp and pusher cylinders on a bottling or canning line, with the automatic drain handling condensate on a line that runs long shifts unattended.
Supplies the air knives and diverter gates on a carton packaging conveyor, where the 1 in NPT port matches a high-consumption header and the check valve holds settings against back-flow.
Conditions the main air drop feeding loom or knitting-machine pneumatics, using the low-pressure regulator type where the machine calls for a lower regulated setpoint than a standard unit targets.
Choose the GFR600 size when your line runs at large port and flow levels - this unit steps up to a 1 in NPT connection. Decide the drain type first: automatic drain (this unit) suits installations that are not checked daily; manual drain suits attended points; the differential-pressure default triggers on a set pressure drop. Filtration is 40 um standard here; specify the W code for 5 um where finer particle removal is needed. This is the low-pressure type regulator, so confirm the adjustment range against your setpoint before ordering. Thread is NPT on this code; PT is the standard and G is also an order option. A mounting bracket is included; no gauge is fitted, and a gauge can be ordered separately.
Because flow is published as curves rather than a single rated figure, we cannot quote one number here - 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. The reflux valve permits reverse flow 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. Send us your application - port size, downstream consumption and line pressure - and we will confirm the sizing from the datasheet on request.
The N in the code means no gauge is fitted with the GFR60025ALNTK. The regulator works the same way; a gauge can be ordered separately if you want to read the regulated pressure at the unit. Ask us to quote the gauge option with your order.
