The AirTAC GFR600C25MC3T AirTAC Filter Regulator NPT1 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 GFR600C25MC3T is a size 600 filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This configuration carries a 1 in NPT port, a 40 um filtration element, and a manual-drain bowl - at size 600 the bowl is aluminium alloy, so it suits installations where a polycarbonate bowl is not preferred. The manual drain is purged by hand, which fits lines with scheduled maintenance stops. A round external gauge with a bar scale is fitted, the regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and the maximum working (inlet) pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drain, a 5 um element alternative (code W), gauge and scale choices, and an optional reverse/check valve. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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.

Filtered, regulated supply to the tool-changer, clamping and chip-clearing circuits of a CNC machining centre, with the 40 um element stripping water and pipe scale and the bar-scale gauge letting setters read the set pressure directly.
Conditioned air for the cylinders and grippers on a carton-forming and case-sealing conveyor, where the 1 in port serves the line's main drop and the manual drain is purged during the scheduled end-of-shift stop.
Point-of-use filter regulation at the head of an assembly cell's air drops, holding a stable set pressure for hand tools and air cylinders while removing condensate carried over from the main distribution loop.
Step through the decodable choices in order. Size and port: 200/300/400/600 step up in port and flow capacity, so match the size to the air demand of the line - this unit is the 600 size with a 1 in port. Drain: manual (this unit) suits attended plants with purge routines; automatic or differential-pressure drain suits unattended duty. Filter grade: 40 um standard, 5 um with code W where finer particulate removal is needed. Gauge: this unit carries a round external gauge with a bar scale; embedded square gauges and MPa/psi scales are the other catalogue choices. Thread: PT is the standard, with G (BSPP) and NPT ordered as options - this unit is NPT. A mounting bracket is included.
One honest note before ordering: AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application's air demand 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 family as curves rather than a single rated figure, so we do not state a flow number. Tell us your application's air demand and line pressure and we will confirm the sizing against the datasheet on request before you order.
The M in the code selects the manual-drain bowl, which is purged by hand - a good fit where maintenance rounds are scheduled. On a manual-drain GFR unit the regulator adjustment range is 0.05-0.9 MPa (7-130 psi); automatic and differential-pressure drain versions are adjusted over 0.15-0.9 MPa (20-130 psi).
