The AirTAC GFR600C25ALF3T 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 GFR600C25ALF3T is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit is built around a 1 in NPT port, with an automatic drain that clears collected condensate from the aluminium alloy bowl without daily manual bleeding, a 40 um standard filter element, and the low-pressure (L) regulator variant. The embedded square gauge reads in bar, and a mounting bracket is included for fixing at the installation point.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options that include manual or differential-pressure drains, a finer 5 um element (code W), PT or G thread, and gauge scales in MPa, psi or bar. Flow is published as curves rather than a single rated figure, so send us your line pressure and air demand and we will confirm the datasheet figures for this model 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.

Feeding a 1 in branch that serves clamp and press actuators on a stamping line, filtering line-scale water and particulate while holding a steady regulated supply pressure at the drop.
Supplying the header that drives gate and stopper cylinders along a bottling conveyor, with the automatic drain handling condensate on a line that cannot pause for manual bleeding.
Regulating low-pressure air to pneumatic control valves on a pilot-plant skid, with 40 um filtration protecting actuator internals and a bar gauge for local set-point checks.
Choose the size and port step against the air demand of the line: 600 is the largest G-series size, and this unit carries it on a 1 in NPT port. Where a bowl is present you can order a differential-pressure drain (the family default), this automatic drain, or a manual drain; the filter element is 40 um as standard with a 5 um (W) option when finer particulate capture matters. The square gauge here reads bar, with MPa and psi scales available, and PT or G thread can be ordered instead of NPT; a bracket is included. This is the low-pressure (L) regulator variant, and its exact adjustment range is not published in the sheet we work from, so tell us your set pressure and we will confirm suitability on request. Because flow is published as curves rather than a single rating, 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 inlet pressure, set pressure and air demand, and we will confirm the datasheet curve figures for this exact model on request before you order.
The L in the code marks the low-pressure regulator variant of the GFR600. Its exact adjustment range is not published in the sheet we transcribe from, so send us your required set pressure and we will confirm it on request. The automatic drain, 40 um element, bar-scale square gauge, 1 in NPT port and included bracket are unchanged.
