The AirTAC GFR600-25 AirTAC Filter Regulator 1 in NPT 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 GFR600-25 is a filter regulator: water and particulate removal plus downstream pressure regulation in a single body. This size 600 unit is built around a 1 in NPT port, with a 40 um filter element as standard, a manual drain bowl in aluminium alloy, a low-pressure regulator type, and a round pressure gauge reading in psi. A mounting bracket is included. Because the filter and regulator share one body, it takes less panel space and needs fewer joints than a separate filter and regulator pair.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options include automatic or differential-pressure drains, a 5 um filter element (code W), square or round gauges with MPa, psi or bar scales, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application 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. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. 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.

Installed at a 1 in drop from a factory compressed-air ring main, it cleans water and scale out of the supply and holds a steady low-pressure feed to the downstream distribution headers.
Mounted on the supply panel of a pneumatic forming press, it conditions the incoming air and lets the setter dial in the regulated pressure the press cylinders were specified for.
Fitted ahead of the valve manifold on a carton-sealing and conveyor line, it removes condensed water before it reaches the valves and keeps the supply pressure stable through shift-long cycling.
Start with the port step: size 600 with a 1 in port suits lines fed at the top of the G-series range; if your compressor-side flow demand is lower, a 400 or 300 body on a smaller port may be the more economical choice. Choose the drain to match attendance: manual drain (as on this model) needs someone to open it, while automatic or differential-pressure drains suit unattended installations. The 40 um element is the standard grade; specify 5 um (code W) only where finer particulate control is needed. This unit is the low-pressure regulator type - confirm the exact regulation range with us before ordering if your setpoint is critical. Gauge scale is selectable (MPa, psi or bar), and threads can be ordered in PT (standard), G or NPT; a bracket is included.
One honest note on sizing: flow for this family is published as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm sizing against the datasheet curves 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, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the flow your application needs, and we will confirm the sizing from the datasheet curves on request before you order.
The M in the code GFR60025MLC2T specifies a manual drain: the bowl is emptied by hand, which suits attended installations on a maintenance round. The same unit can be ordered with an automatic drain (code A) or the default differential-pressure drain for unattended service. This size 600 bowl is aluminium alloy, and the standard filter grade is 40 um (a 5 um element is available as code W).
