The AirTAC GFR600C25MLJC3WT AirTAC Filter Regulator NPT1 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 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 GFR600C25MLJC3WT 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 built around a 1 in NPT port, a manual drain on the aluminium alloy bowl (size 600 bowls are aluminium alloy), a 5 um filter element (the fine W grade; 40 um is the standard element), the low-pressure regulator type, and a round pressure gauge with a bar scale. It is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family runs from size 200 to 600 with ports from 1/8 in up to 1 in, and can be ordered with differential-pressure, automatic or manual drains, 40 um or 5 um elements, embedded square or optional external round gauges in MPa, psi or bar scales, PT, G or NPT threads, and with or without a bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and 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.

Mounted on the 1 in main air drop feeding a row of pneumatic presses, this unit cleans shop compressed air down to 5 um and holds a steady regulated supply to the press valves and cylinders. The low-pressure regulator type is the version intended for circuits controlled at the lower end of the range, and the manual drain suits a press shop where bowls are checked during scheduled maintenance rounds.
Air-jet loom rooms run large volumes of conditioned compressed air to the weaving jets. This size 600 unit on the loom supply line removes water and particulate before the jets, and the 5 um element helps keep fine orifice passages clear. The manual drain fits a weaving shed with fixed shift checks, and the 1 in NPT port matches the loom room's main distribution piping.
On a bottling line, actuated fill, capping and divert valves depend on clean, stable air. This filter regulator conditions the branch feeding those valve actuators: the 5 um element protects valve seats and seals, the regulator holds a consistent supply pressure to the actuators, and the manual drain is emptied at changeover as part of the line's cleaning routine.
Every choice in this unit is decodable from the code. Step through sizes 200, 300, 400 and 600 - larger sizes carry larger ports and more flow - and match the port to your piping; this unit is the size 600 body with a 1 in NPT port. Choose the drain: differential-pressure (the default), automatic (code A) or manual (code M, fitted here); manual draining suits attended installations where someone checks the bowl on a routine. Choose the element: 40 um standard or 5 um (code W, fitted here) where downstream equipment needs finer protection. Gauges are embedded square as standard with an optional external round gauge in MPa, psi or bar scales; this unit carries a round gauge with a bar scale. Thread is PT as the standard, with G and NPT as order options, and a bracket can be added if the unit is not line-mounted. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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 number here. Tell us your application - pipe size, connected equipment and working pressure - and we will confirm the flow and the rest of the datasheet figures for the GFR600C25MLJC3WT on request before you order.
The M in the code sets a manual drain: collected water is removed by opening the drain at the aluminium alloy bowl, which suits attended installations covered by a maintenance routine. The same size 600 unit can be ordered with a differential-pressure drain (the default) or an automatic drain (code A) instead - just ask for the alternative code when ordering.
