The AirTAC GFR60025MLJC3T 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60025MLJC3T is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration is built around a 1 in NPT port, a manual drain bowl in aluminium alloy, and the standard 40 um filter element. It is the low-pressure regulator type, fitted with an external round gauge scaled in bar, and it carries no reverse/check valve and no mounting bracket. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT (standard), G and NPT threads, differential-pressure, automatic or manual drains, a 5 um element option (code W), and a choice of gauge scales. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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. 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 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. |
| 3 | Gauge scale: bar. 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. |
| (blank) | No reverse-flow valve (the default). |
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 a paint spray booth's atomizing air line where the process runs at reduced pressure: the 40 um element strips water and pipe scale ahead of the gun while the low-pressure regulator holds the setpoint, read on the fitted bar gauge.
Installed on the air header of a dilute-phase conveying system for powders, where the low-pressure regulator type matches the modest conveying pressures and the 1 in NPT port suits the header take-off.
Placed on the conditioned-air feed to air-jet weaving machines, filtering moisture and particles from the mill air line and regulating the supply pressure to the loom's jet circuit.
Start with the port step: size 600 with a 1 in NPT port is the largest GFR offering, so match it against the air demand of the line it will feed; if the demand is modest, a smaller 200/300/400 size with a smaller port may suit better. This unit uses a manual drain, which means an operator opens the drain periodically - if nobody is on site to do that, consider the automatic or differential-pressure drain variants instead. The 40 um element is the standard grade; specify the W option if the application needs 5 um filtration. The fitted round gauge reads in bar; square embedded gauges and MPa/psi scales are the other catalogue choices. Thread here is NPT; PT is the standard and G is the alternative order option. This unit ships without a mounting bracket (J code) and without a reverse/check valve.
Because flow for this family is published as curves and not as a single rated number, ask us to confirm sizing against your application before ordering.
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 application's air demand and we will confirm the sizing from the datasheet on request.
The M in the code specifies a manual drain: an operator periodically opens the bowl drain to remove collected water. The catalogue also offers automatic (A) and differential-pressure (blank) drains on GFR units, which remove condensate without manual attention - choose those if the installation is unattended.
