The AirTAC GFR600C25ALC3TK 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 AirTAC GFR600C25ALC3TK is a 600-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is ported NPT 1 in, uses the low-pressure regulator type, and carries a 40 um filter element with an automatic drain, so condensate is expelled from the aluminium alloy bowl without manual attention. A round gauge scaled in bar is fitted for local pressure reading, a reverse/check valve is fitted, and the mounting bracket is included.
This is a genuine AirTAC part. GFR filter regulators are published in 200, 300, 400 and 600 sizes, with 600 being the largest port and flow step in the range, and with options across drain type, filter grade, gauge style and scale, thread form and mounting. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Feeds filtered, regulated air to the large clamping and hold-down cylinders on a metal stamping press, with the 1 in port matching the high-consumption main drop at the press.
Conditions the air feeding pneumatic actuators on a bottling line's filler and capper stations, with the automatic drain clearing condensate from the bowl during continuous running.
Supplies regulated air to pneumatic hold-down clamps and chip-blow nozzles on a CNC sawing cell, with the bar-scaled gauge giving operators a local setpoint reading.
Step up or down through the 200/300/400/600 sizes against the port and flow your line needs; this unit is the 600 size on a 1 in NPT thread. Where a bowl is fitted, choose the drain: automatic (this unit), manual, or the differential-pressure default. Filter grade is 40 um standard, with 5 um available as the W option if finer particulate capture is needed. Gauge style and scale can be specified, and PT is the standard thread with G (BSPP) and NPT as order options; a bracket is included here.
Flow for this family 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 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and sizing figures from the datasheet on request.
The automatic drain expels collected condensate from the bowl without anyone opening it, which suits unattended or continuously running installations. Manual-drain and differential-pressure-drain versions are available in the family if you would rather control draining yourself.
