The AirTAC GFR600C25MLC1T 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 See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR600C25MLC1T is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 600 unit carries a 1 in NPT port, a manual drain on the metal bowl (size 600 bowls are aluminium alloy), a 40 um standard filter element, and a low-pressure regulator type with a round MPa pressure gauge fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. A mounting bracket is included.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, a choice of differential-pressure, automatic or manual drains, a 5 um element (code W) where finer filtration is needed, and gauge scales in MPa, psi or bar. Because AirTAC publishes flow as curves rather than a single rating, ask us to confirm flow and other 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

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 bagging-machine cylinders and clamps that run at reduced set pressures, with the manual drain emptied during scheduled changeovers.
Supplying clean, regulated air to the gate and stopper cylinders that divert cartons between lanes, with the 40 um element keeping debris out of the directional valves.
Providing a filtered, low-pressure pilot supply to pneumatic valve actuators on a process line, with the round MPa gauge giving a clear local setpoint reading.
Choose the size and port step against the air your circuit actually uses: 200, 300, 400 and 600 step up in port and flow capacity, and this unit sits at the top of the range with a 1 in NPT port. Drain type is a real decision: manual (as here) means the bowl is drained by hand on a schedule, while automatic and differential-pressure variants in the series handle condensate without attention. The 40 um element is standard; specify code W for a 5 um element where finer filtration is needed. Gauges are available with MPa, psi or bar scales, and the thread can be ordered as PT (standard), G or NPT. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing from 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 series as curves rather than a single rated figure, so we do not quote a number here. Send us your port size, operating pressure and air demand, and we will confirm the flow from the datasheet for this exact model before you order.
The M in the code means the bowl drain is operated by hand, so it should be emptied as part of a routine maintenance schedule. The same series is also available with an automatic drain (code A) or a differential-pressure drain (no code) if you would rather not rely on manual draining.
