The AirTAC GFR600C25MLC3WT 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 GFR600C25MLC3WT is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 600 unit is built for 1 in NPT ports, is the low-pressure regulator type, and carries a 5 um filter element (code W) with a manual drain on the bowl. The bowl on size 600 units is aluminium alloy, a mounting bracket is included, and a round pressure gauge reading in bar is fitted. 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 spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include 40 um or 5 um filtration, differential-pressure, automatic or manual drains, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Because AirTAC publishes flow only as curves rather than a single rating, we confirm flow and other datasheet 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.

Conditioning the air feeding pneumatic clamping fixtures on a machining centre that runs its clamp circuit at reduced pressure. The 5 um element protects the directional valves and the manual drain suits a supervised maintenance round.

Size and port step up together: GFR sizes 200, 300, 400 and 600 cover ports from 1/8 to 1 in, so match the port to your line size and let us confirm the flow curve against your demand before ordering. This unit is the low-pressure type, so specify it where the circuit works below the standard regulator range; the exact adjustment span for the low-pressure version is confirmed from the datasheet on request. Drain choice matters: manual (this unit, code M) releases condensate only when operated, automatic drains continuously, and the differential-pressure default drains on a pressure drop. Filter grade is 40 um standard or 5 um with code W, as fitted here. Gauges are the embedded square type or an external round gauge in MPa, psi or bar; thread is PT as standard with G and NPT as order options, and a bracket is included unless code J is specified.
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 this family as curves rather than a single rated figure, so we do not quote a number. Send us your line size and air demand and we will confirm the flow from the datasheet for this exact 1 in NPT, low-pressure configuration before you order.
The manual drain (code M) releases accumulated condensate only when operated, which suits installations checked on a maintenance round. If the unit sits where nobody opens the drain regularly, ask about the automatic or differential-pressure drain versions of the same GFR600 size.
