The AirTAC GFR60025MLJF2W AirTAC Filter Regulator 1 in PT, 5 um 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 GFR600 series combines water and particulate filtration with pressure regulation in a single body, and this configuration, GFR60025MLJF2W, is built for a 1 in PT port. It carries the W filter grade (5 um element, against the 40 um standard), a manual drain on the bowl, the low-pressure regulator type, an embedded square gauge scaled in psi, and no mounting bracket. At size 600 the bowl is aluminium alloy, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include automatic or manual drainage, the 5 um element, G (BSPP) or NPT threads in place of the PT standard, gauge scale choices, a reverse/check valve and a mounting bracket. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

|---|---|
| 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. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT 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 filtered, low-pressure regulated air to the supply drop serving a spray booth's pneumatic atomizing circuit, with the 5 um element protecting the application point from fine particulate carried in shop air.
Sits at the head of the air drop feeding cylinder-driven diverters and stop gates on a packaging conveyor, filtering water and grit out of the supply while the low-pressure regulator holds the working pressure the actuators were set up for.
Provides cleaned and regulated air to a laboratory or QA test rig where the operator sets pressure by hand and reads it on the psi gauge, with the manual drain bled down between test sessions.
Start with the port step: this unit is size 600 with a 1 in PT port, the largest in the GFR range, so step down to 300 or 400 only if your line's flow demand allows a smaller connection. The drain choice matters in service: this code has the manual drain, which suits installations where an operator can bleed the bowl on a schedule; choose the automatic drain code instead for unattended duty. The 5 um element (code W) is the right pick where downstream valves or instruments are sensitive to fine particulate; the 40 um standard element is the general-purpose choice. The square gauge here is scaled in psi; MPa and bar scales are available, and an external round gauge is optional. PT is the standard thread, with G (BSPP) and NPT as orderable options, and a bracket can be added if the unit will not be piped with its own support.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so we cannot quote you a flow number from the code alone. Send us your application's flow and pressure requirements and we will confirm the correct size 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 the GFR family as curves rather than a single rated number, so there is no one flow figure we can quote from the model code. Send us your required flow and working pressure and we will confirm the sizing against the datasheet on request before you order.
The M in the code specifies a manual drain on the filter bowl: collected water and contaminant are released by hand when the operator opens the drain. It suits installations with regular operator presence; for unattended lines, order the automatic drain variant instead. Note that the regulator's adjustment range depends on the drain type, and for this low-pressure type the exact range is not published, so we will confirm it from the datasheet on request.
