The AirTAC GFR600-25MLJF2T 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 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 GFR600-25MLJF2T is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1 in NPT port, a 40 um standard filtration element, a manual drain bowl in aluminium alloy, a low-pressure regulator type, and a fitted square gauge scaled in psi. No reverse/check valve is fitted and no mounting bracket is included, so plan your mounting accordingly.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and options including automatic or differential-pressure drains, a 5 um element (code W), alternative gauge scales in MPa or bar, and G (BSPP) or NPT threads in place of the PT standard. 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". |
| 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). |
| F | Gauge shape: Square. 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. |
| (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.

At the 1 in main air drop feeding a stamping or forming press, this unit filters water and scale from the header supply and holds a steady low regulated pressure to the press cylinders, with the square psi gauge giving operators a direct reading at the machine.
On a carton erector or case sealer running many cylinders and actuators from a large-diameter supply, the filter section keeps condensate and particles out of valves while the low-pressure regulator holds the gentle, consistent pressure those actuators are set up for.
Where a row of impact wrenches, nutrunners or air hoists shares a 1 in manifold, this filter regulator cleans the supply and lets each bay's pressure be set and read locally, with the manual drain bled during scheduled maintenance rounds.
Size 600 with a 1 in NPT port is the largest step in the GFR range, chosen when your line's flow demand calls for the biggest port and body in the series; step down to 400/300/200 if your circuit is smaller. Drain choice matters: this unit has a manual drain, so someone must bleed the bowl on a routine basis - choose automatic or differential-pressure drain variants if the installation is unattended. The 40 um element is the standard grade; specify the W variant for 5 um when downstream equipment needs finer filtration. The fitted square gauge reads in psi; MPa or bar scales are available, and an external round gauge is an option. Thread is NPT here; PT is the catalogue standard and G (BSPP) can be ordered. No bracket is fitted (code J), so plan a rigid pipe or panel mounting arrangement. Because flow is published as curves rather than a single rating, 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a number. Send us your application - port size, downstream demand and line pressure - and we will confirm the sizing against the datasheet on request before you order.
The M in the code means the aluminium alloy bowl is drained by hand, so it suits attended installations on a maintenance schedule; automatic or differential-pressure drain variants exist for unattended lines. The L in the code marks the low-pressure regulator type, intended for circuits set below standard regulator ranges - its exact adjustment range is not published in the material we hold, so confirm it with us and we will check the datasheet.
