The AirTAC GFR60025MLJC3TK 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 GFR60025MLJC3TK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and holds a regulated downstream pressure. This 600-size unit is threaded 1 in NPT, carries a 40 um filter element, the low-pressure regulator type, a manual drain on the aluminium-alloy bowl, a round gauge scaled in bar, and a built-in check valve; it is supplied without a mounting bracket. 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 G-series filter-regulator line spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um (W) elements, standard or low-pressure regulation, gauge and thread options, and bracket choices. Flow is published as curves rather than a single rating, so ask us to confirm the 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.
| 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. |
| 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.

Supplies filtered, regulated air at a low set pressure to pneumatically actuated process valves, with the built-in check valve blocking backflow toward the supply side.
Feeds clean, pressure-controlled air to sealing jaws and clamp cylinders on a packaging machine, with the manual drain bled as part of the shift-start routine.
Provides a filtered, low-pressure regulated air source for bench rigs and test fixtures, where the operator sets and reads the bar-scaled gauge directly.
Choose the size by port and demand: 600 is the largest step in the range, here with a 1 in NPT port. The manual drain suits installations where an operator bleeds the bowl on a routine; automatic (A) and differential-pressure (blank) drains are the catalogue alternatives where unattended draining is preferred. The 40 um element is the standard grade; specify W for the 5 um option when finer filtration is needed. The round gauge on this unit is scaled in bar; the embedded square gauge and MPa or psi scales are the other options. Thread is NPT here; PT is the standard and G (BSPP) is also orderable. This configuration has no bracket. Because flow is published as curves, not a single rating, 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. 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 one number. Tell us your line pressure and air demand and we will confirm the datasheet curve and correct sizing on request before you order.
It selects the low-pressure regulator type, intended for applications set below the standard type's range. The exact regulation range for the low-pressure type is not published on our sheet, so confirm it with us on request; for reference, the standard type with a manual drain adjusts over 0.05-0.9 MPa (7-130 psi).
