The AirTAC GFR600C25MF3WTK 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 GFR600C25MF3WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint, in one body. This size-600 unit is built around a 1 in NPT port, and this configuration comes with a 5 um filter element (W grade), a manual drain on the aluminium alloy bowl, an embedded square gauge scaled in bar, a reverse/check valve fitted, and a mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and because the drain is manual the regulation range is 0.05-0.9 MPa (7-130 psi).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in up to 1 in, in PT (standard), G and NPT threads, with a choice of drain type, 40 um standard or 5 um filtration, gauge style and scale, and an optional reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm flow 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.

On a 1 in shop-air main feeding a CNC cell, this filter regulator cleans the supply and holds a steady setpoint to pneumatic clamps and tool-change actuators, while the check valve keeps the setting if upstream pressure drops.
Bottling and capping machines run banks of air cylinders that need clean, dry, pressure-stable air; this unit filters water and particulate at the line drop and lets the crew set and read the line pressure on the bar gauge.
Conveyor diverter gates and carton pushers misbehave when pressure wanders; mounting this filter regulator at the packaging line take-off gives the station filtered air at a fixed setting, with the manual drain used at shift checks.
Step up size and port with flow demand: 200 for small drops, 300/400 for individual machine supply, and 600 for a 1 in main line like this unit. The real choices inside the code are: drain type (manual here - simple and positive, versus automatic or differential-pressure), filter grade (5 um W grade here versus the 40 um standard), gauge (embedded square, bar scale here; an external round gauge in MPa, psi or bar scale is optional), thread (PT is the standard; G and NPT are catalogue options such as the NPT on this unit), bracket, and the reverse/check valve fitted here to hold downstream pressure if the supply fails. As a manual-drain unit its regulation range is 0.05-0.9 MPa (7-130 psi).
Flow for the GFR series is published as curves, not a single rated figure, so we do not quote a number here. Send us your application details and we will confirm sizing against the datasheet curves 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 series as curves, not as a single rated figure, so we do not quote a l/min or SCFM number. Tell us your line pressure and the equipment you are feeding, and we will confirm the flow from the datasheet curves for this exact model before you order.
The M in the code is the manual drain: the bowl is emptied by hand at service intervals, which suits attended installations. The same GFR600 size is available with an automatic drain (code A) or the differential-pressure drain (blank), and note that manual-drain units carry the wider 0.05-0.9 MPa (7-130 psi) regulation range. This unit also has a 5 um element, a square bar gauge and a check valve fitted; all of these are decodable choices you can swap when ordering.
