The AirTAC GFR600C25MLNT 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 GFR600C25MLNT is an AirTAC GFR-series filter regulator: a single body that first removes water and particulate from compressed air, then regulates downstream pressure. This size-600 unit is supplied with a 1 in NPT port, a manual drain bowl in aluminium alloy, a standard 40 um filter element, and the low-pressure regulator type. No gauge is fitted on this configuration, and the 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 manual, automatic or differential-pressure drain, a 40 um standard or 5 um (code W) element, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm 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 tapped from a 1 in main feeding a production hall's pneumatic drop lines, with manual drain suited to a supervised compressor room.
Conditioning the air feeding clamps and cylinders on a fabrication cell, where clean, regulated low-pressure air holds the fixture sequence consistent.
Supplying air to diverters, stoppers and lifters on a bottling or carton conveyor line, with the 40 um element protecting valve spools from water and debris.
Size 600 with a 1 in port is the largest step in the GFR range, so start there when the line's required flow points to the top of the family; we can check the published flow curves against your demand before you order. This unit has a manual drain, which suits installations where an operator drains the bowl as part of a routine; choose automatic or differential-pressure drain codes if the bowl cannot be attended. The 40 um element is the standard grade - specify the W code only if the application needs the 5 um option. Thread is NPT here; PT is the catalogue standard and G (BSPP) is also an order option. The included bracket simplifies wall or panel fixing. Note this is the low-pressure regulator type, and its exact adjustment range is not published - confirm it with us if your setpoint is critical.
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 series as curves, not as a single rated figure, so we do not quote a number that is not in the datasheet. Tell us your line demand and we will confirm the sizing against the published curves and send the datasheet on request.
The M code in GFR600C25MLNT specifies a manual drain bowl, which an operator empties as part of routine checks; automatic or differential-pressure drain versions are available if the bowl cannot be attended. The N code means no gauge is fitted on this configuration, so add a gauge variant if you need a visible setpoint. This is also the low-pressure regulator type; its exact adjustment range is not published, so confirm it with us before ordering.
