The AirTAC AirTAC GFR60025MLJC1WT Filter Regulator NPT1 5um is a genuine G-series filter regulator: water separation, 5 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 GFR60025MLJC1WT is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built for a 1 in NPT port, carries the 5 um filter element (code W) for finer filtration than the standard 40 um grade, and uses a manual drain, so the bowl is drained by opening its valve during routine checks rather than automatically. The bowl on this size is aluminium alloy, an external round pressure gauge with an MPa scale is fitted, and this is the low-pressure regulator type. No mounting bracket is included, so plan a rigid connection or your own support.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and PT, G or NPT threads. AirTAC publishes flow for this family as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

|---|---|
| 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. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 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.

Feeding filtered, regulated air to a big pneumatic press or forming machine on a 1 in main, where the 5 um element protects the press valves from water and fine particles.
Regulating supply to pneumatic clamps and holding fixtures that run at reduced pressure, using the low-pressure type regulator to set the circuit from a higher plant header.
Conditioning the high-volume air feed to conveyor cleaning nozzles or air knives, where the manual drain lets maintenance drain the aluminium bowl during scheduled rounds.
Start with the port and size: this unit steps up to 1 in NPT, the largest port in the GFR range, so match it to the air consumption of the machines it feeds. Choose the drain to suit access: manual (as here) needs someone to open the drain valve periodically, while automatic and differential-pressure drains discharge condensate without that step. Choose the 5 um element (this unit) where downstream valves and cylinders need finer air than the standard 40 um grade. Gauge options are the embedded square gauge or an external round gauge, with MPa, psi or bar scales - this unit has a round gauge reading MPa. Thread is NPT here; PT is the standard and G is also a catalogue option. Brackets are optional, and this code omits one.
Two honest routing notes: flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering; and this is the low-pressure regulator type, so tell us your working pressure and we will confirm suitability from the datasheet.
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 and air demand and we will confirm the sizing from the datasheet on request.
The M in the code selects a manual drain: condensate collects in the aluminium alloy bowl and is released by opening the drain valve during routine checks. If you cannot schedule that, the same unit is available with an automatic or differential-pressure drain instead.
