The AirTAC GFR600-25ALJC2TK 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 GFR600-25ALJC2TK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This 600-size configuration is built with a 1 in NPT port, an automatic drain that clears collected condensate from the aluminium alloy bowl without a manual check, a 40 um filter element, and the low-pressure regulator type. An external round gauge with a psi scale is fitted and a reverse/check valve is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| 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. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 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. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Water removal and pressure regulation on a 1 in distribution header feeding air tools and pneumatic clamps along a vehicle assembly line, with the automatic drain handling condensate on a header that is not checked daily.
Filtered, regulated low-pressure air for blow-off nozzles that clear rinse water and label residue from bottles travelling on a high-speed filling-line conveyor.
Conditioning the main air feed to pneumatic looms, where the 40 um element and automatic drain keep water and particulate out of the weaving control circuit without manual bowl draining.
Size and port are the first choices: 600 is the largest G-series size, and this unit steps up to a 1 in port, so it belongs on a main header or large machine supply rather than a point-of-use drop. This particular code is already fixed as automatic drain, 40 um standard filtration, low-pressure regulator type, external round gauge on a psi scale, reverse/check valve fitted, no mounting bracket, and NPT thread (PT is the AirTAC standard; G and NPT are order options). If you would rather pick drain type, filter grade (40 um vs 5 um), gauge scale or thread yourself, those are decodable choices across the other GFR600 codes.
Flow is published by AirTAC as curves, not a single rated figure, so we cannot honestly quote one number here. Send us your application details and we will confirm the datasheet and check the sizing against your demand 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 rather than a single rated figure, so we do not quote one number here. Tell us your line pressure and air demand and we will confirm the datasheet curve and check the sizing against your application on request.
The A in this code fits the automatic drain, which expels collected condensate from the aluminium alloy bowl without a manual check - useful on headers that are not visited daily. Manual and differential-pressure drains are decodable options on other GFR600 codes, as is the 5 um element (code W).
