The AirTAC GFR600C25AJF1WTK AirTAC 1 in NPT Filter Regulator 5 um 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 GFR600C25AJF1WTK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a 1 in NPT port, a 5 um filter element (the finer of the two catalogue grades), an automatic drain that discharges collected condensate without manual attention, and a reverse/check valve fitted to hold downstream pressure. The aluminium alloy bowl is standard at size 600, and the embedded square gauge on an MPa scale lets you read the regulated outlet pressure directly. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator covers 0.15-0.9 MPa (20-130 psi) with automatic drain, and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include the 40 um standard element, manual or differential-pressure drain, psi or bar gauge scales, an external round gauge, PT or G thread, and a mounting bracket (this unit is ordered without one). Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Drops in clean, regulated air to carton sealers, case erectors and stretch wrappers on the plant floor, with the 5 um element and auto drain keeping the supply dry without daily bowl checks.
Feeds pneumatic diverters, stoppers and lifters along a bottling or food conveyor, holding a steady regulated pressure so cylinder stroke behavior stays consistent through the shift.
Supplies workholding clamps and swing cylinders on a machining center, where the check valve helps hold the set downstream pressure and the square MPa gauge gives the operator a direct reading.
Size 600 with a 1 in NPT port is the largest step in the GFR range, so start by matching the port and the expected air demand of the line - and because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. This unit already carries the finer 5 um element (the 40 um standard grade is the alternative if your application does not need finer filtration) and the automatic drain, which suits unattended installations; manual and differential-pressure drains are the other catalogue choices. The embedded square gauge reads in MPa, with psi and bar scales and an external round gauge available as options. PT is the standard thread and G/NPT are order options - this unit is specified with NPT. A mounting bracket is optional; this code is ordered without one.
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 number, so we do not quote a l/min, m3/h or SCFM figure. Tell us your inlet pressure and the air demand of your equipment and we will confirm the sizing from the datasheet on request before you order.
The A in the code selects the automatic drain, which discharges collected condensate from the aluminium alloy bowl on its own - useful for installations that run unattended. With an automatic drain the regulator adjustment range is 0.15-0.9 MPa (20-130 psi); the manual-drain variant of this family covers 0.05-0.9 MPa (7-130 psi).
