The AirTAC GFR600C25AJF3TK AirTAC Filter Regulator NPT1 (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 GFR600C25AJF3TK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1 in NPT port, an automatic drain that purges collected condensate without manual attention, a 40 um standard filter element, an embedded square gauge scaled in bar, and a reverse/check valve fitted. The size-600 bowl is aluminium alloy, and no mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, and gauge or no-gauge variants. Flow is published as curves rather than a single rating, 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.

Filters water and pipe scale out of the air feeding paint spray stations and holds a steady regulated pressure so atomising air at the booth stays consistent through the shift.
Sits at the drop feeding pneumatic cylinders on a carton-sealing or palletising conveyor, keeping condensate and debris out of the actuators while holding set pressure.
Conditions the shop-air supply to a CNC machine tool, protecting the machine's pneumatic clamps and tool-change circuit from moisture and particles at a stable pressure.
Step up through the GFR sizes (200, 300, 400, 600) as your port and air demand grow; this size-600 unit sits at the top of the range with a 1 in NPT connection. Drain choice matters: automatic drain suits points you cannot service often, manual drain suits attended installations, and the differential-pressure default triggers on pressure drop. Filter grade is 40 um as standard here; specify code W for 5 um where finer particle capture is needed. Gauge scale is selectable (MPa, psi or bar) and this code carries the square gauge in bar. NPT is an order option alongside the PT standard and G thread, and brackets are optional on GFR. Because flow is published as curves rather than a single rated figure, 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 GFR flow 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 datasheet figures for this unit on request before you order.
The A in this code specifies an automatic drain, which purges collected condensate from the bowl without anyone opening it - useful for unattended or hard-to-reach installations. The GFR family is also available with a manual drain or the differential-pressure default, and the filter grade can be changed from the 40 um standard to 5 um with code W.
