The AirTAC GFR600C25MC3WT AirTAC Filter Regulator NPT 1 in 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 GFR600C25MC3WT 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 threaded 1 in NPT, carries the 5 um filter element (code W) for finer filtration than the standard 40 um grade, uses a manual drain on the bowl, and includes a round pressure gauge with a bar scale. The maximum working (inlet) pressure is 1.0 MPa (145 psi), the regulator adjustment range is 0.05-0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, standard or low-pressure regulation, gauge options and scale choices, PT, G or NPT threads, and bracket options. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.

Drops in at the 1 in header feeding a production hall, cleaning the compressed air and holding a set header pressure for every machine downstream.
Feeds the valve manifold and cylinders on a conveyor or palletising line, keeping water and fine debris out of the valves while holding steady actuation pressure.
Sits ahead of a control cabinet's air distribution block, delivering filtered, regulated air to instruments and pilot circuits at a fixed setpoint.
Size 600 with a 1 in port is the largest step in the GFR range - choose it when your line port and required flow sit at the top of the family; the smaller 200/300/400 sizes cover 1/8 in to 3/4 in. This unit has the 5 um element (W): pick it over the standard 40 um grade when downstream components need finer protection. The manual drain (M) means an operator opens the bowl drain periodically - choose the automatic or differential-pressure drain variant instead where unattended drainage matters. The round gauge here reads in bar; square embedded gauges and MPa or psi scales are also catalogue options. NPT is the thread on this code; PT (standard) and G (BSPP) versions can be ordered. A mounting bracket is included.
Because AirTAC publishes flow only as curves and not as a single rated number, ask us to confirm sizing against your application's flow demand before ordering.
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 number. Tell us your application's flow demand and we will confirm the sizing from the datasheet on request.
The M in the code selects the manual drain: collected condensate must be drained from the aluminium alloy bowl by opening the drain by hand at service intervals. If you prefer unattended drainage, the same size is available with an automatic or differential-pressure drain - ask us for those model codes.
