The AirTAC GFR600C25AJF1TK AirTAC Filter Regulator NPT1 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 GFR600C25AJF1TK is a size-600 filter regulator: water and particulate removal plus downstream pressure regulation in a single body. This configuration is built around a 1 in NPT port for high-flow main air lines, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and an embedded square gauge scaled in MPa so the set pressure is visible at a glance. A reverse/check valve is fitted to hold downstream pressure when the upstream supply is lost, and the unit is supplied without a mounting bracket. At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part from the GFR range, which 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, 40 um or 5 um (W) filtration, gauge scale options, and PT, G or NPT threads. Rated inlet pressure is 1.0 MPa (145 psi) with a regulation range of 0.15-0.9 MPa (20-130 psi) and an operating temperature of -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, so ask us to confirm the 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.

Installed at the drop feeding pneumatic impact tools and clamping fixtures on a vehicle assembly line, cleaning water and scale from the main header and holding a stable regulated pressure for consistent tool torque.
Mounted ahead of the valve manifold driving conveyor stoppers, pushers and case-eject cylinders on a bottling or carton line, protecting the actuators from condensate and keeping their operating pressure steady through shift changes.
Fitted on the shop-air feed to a CNC machining centre, conditioning the supply that actuates the tool changer, chuck and coolant-spray valves, with the check valve holding downstream pressure during momentary supply dips.
Size 600 with a 1 in NPT port suits main-line air preparation where the largest G-series port step is required; step down to GFR200/300/400 if your piping and expected flow are smaller. Drain choice matters: automatic drain (this unit) suits unattended or hard-to-reach installations, manual drain suits supervised points, and the differential-pressure default drains on a pressure drop. Filtration is 40 um standard here; specify the W code if you need 5 um. The square gauge is scaled in MPa, with psi or bar scales and an external round gauge available as options. Thread is NPT on this unit; PT is the standard and G is also an orderable option. No mounting bracket is included (J code). 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 this series as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and we will confirm the relevant flow figures from the datasheet on request before you order.
The A code in this model means an automatic drain: collected condensate is expelled from the aluminium bowl without anyone opening it, which suits unattended installations. The GFR series is also available with a manual drain or the differential-pressure default drain, and the filter grade can be changed from the standard 40 um to 5 um with the W code.
