The AirTAC GFR600C25MF3WT 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 AirTAC GFR600C25MF3WT is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 1 in NPT port, a 5 um filter element (the fine option; 40 um is standard), a manual drain on the bowl, and an embedded square gauge reading in bar. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C, non-freezing. The size-600 bowl is aluminium alloy.
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, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, square or round gauges with MPa, psi or bar scales, PT, G or NPT threads, and an optional reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm the 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. 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.

Installed at the drop to a spray booth or paint kitchen, this unit filters water and particles from the compressed air supply and holds a steady regulated pressure to the application equipment, with the 5 um element protecting the finishing process from contamination.
Mounted on the air inlet of a packaging or carton-sealing line, it cleans the supply air and regulates the pressure feeding cylinders and grippers, with the bar-scale square gauge giving operators a clear setpoint readout at the machine.
Fitted ahead of the pneumatic clamping and tool-change circuit on a machining centre, it removes condensate and fine particulate and regulates the supply to the clamp actuators, with the aluminium alloy bowl and manual drain suiting a supervised machine bay.
Start with the port step: this unit is the size-600 frame with a 1 in NPT connection, the largest in the GFR range, so match it to the line size and the flow your circuit needs. Choose the drain to suit access: manual drain (this unit) requires someone to open it periodically, while automatic and differential-pressure drains handle condensate without attention. Choose the element grade: 40 um is the standard element and 5 um (this unit, code W) is the finer option for downstream equipment that needs cleaner air. Gauge scale is selectable (MPa, psi or bar; this unit reads bar on the embedded square gauge, with an external round gauge optional), and thread can be ordered as PT (standard), G or NPT. A mounting bracket is included. Flow is published as curves, not a single rated figure, so 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 the GFR series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your line size, pressure and expected air demand and we will confirm the flow figures from the datasheet for this exact model on request.
The M in the code specifies a manual drain: condensate collected in the bowl is released by hand, which suits installations that are checked regularly. The GFR family is also available with automatic or differential-pressure drains that remove condensate without attention, and with the standard 40 um element instead of the 5 um element fitted here. Ask us to quote the variant you need.
