The AirTAC GFR600C25MF3TK 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 GFR600C25MF3TK is a 600-size filter regulator that removes water and particulate from compressed air and holds downstream pressure at your setpoint in one body. This configuration carries a 1 in NPT port, a 40 um standard filter element, a manual drain on the bowl, an embedded square gauge scaled in bar, and a built-in reverse/check valve that holds the downstream setting when upstream pressure is lost. The 600-size bowl is aluminium alloy, and the unit is rated to 1.0 MPa (145 psi) maximum inlet with a 0.05-0.9 MPa (7-130 psi) regulation range, operating from -5 to 70 C in non-freezing conditions. A mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, a 5 um (code W) element option, gauge scale choices, G/NPT thread options and an optional no-bracket build. Flow is published as curves rather than a single rating, so ask us to confirm sizing or any datasheet figure 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.

Installed at the 1 in drop from the plant air ring main, it strips water and scale from the supply and holds a steady setpoint to the machines below, with the check valve keeping the circuit pressurised during compressor unload or upstream loss.
Feeding the cylinder and valve manifold bank on a packaging or palletising conveyor line, it gives the line one filtration and regulation point, with the manual drain cleared at shift start and the bar gauge giving operators a visible line check.
Supplying air to clamping fixtures and pneumatic presses where a stable setpoint protects part quality, it filters the incoming supply to 40 um, regulates downstream pressure, and the check valve prevents the fixture from venting if the main is shut off.
Start with the port step: this unit is the 600 size with a 1 in NPT connection, the largest in the GFR range, so match it to lines where 1/2 in and smaller units would restrict the circuit. Choose the drain to suit access: this build is manual drain, which suits attended installations where an operator blows down the bowl; automatic or differential-pressure drain codes suit unattended lines. The 40 um element is the standard grade; specify the W code for 5 um when downstream equipment needs finer filtration. The square gauge here reads in bar; MPa and psi scales are available, and an external round gauge is optional. Thread is NPT on this unit; PT is the standard catalogue thread and G (BSPP) is also an order option. A bracket is included; a J code removes it. Flow for the GFR range 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 range as performance curves rather than a single rated figure, so we do not quote one number. Send us your application details and we will confirm the flow and full datasheet figures for this 1 in unit on request before you order.
The M code in GFR600C25MF3TK specifies a manual drain, so the bowl is blown down by hand, which suits attended installations. The same 600-size filter regulator can be ordered with automatic (A) or differential-pressure (blank) drain if the line runs unattended.
