The AirTAC GFR600C25NTK 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 GFR600C25NTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single 600-size body with a 1 in NPT port. This configuration carries the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises, and a fitted reverse (check) valve that holds the downstream setting when inlet pressure is lost. The outlet pressure is set anywhere in the 0.15-0.9 MPa (20-130 psi) range, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, a choice of PT, G or NPT thread, differential-pressure, automatic or manual drains, a 40 um standard or 5 um (W) element, and optional gauge arrangements. Flow figures are 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.

Filtered and regulated plant air feeding spray-booth air tools and atomising circuits, where the 40 um element keeps water and pipe scale out of the finishing equipment and the regulator holds a steady booth pressure.
Supplying a packaging conveyor's pneumatic cylinders and grippers, with the check valve holding the set pressure against upstream dips so the sealing heads do not lose stroke mid-cycle.
Conditioning the air that actuates workpiece clamps and tool-change cylinders on a machining centre, where clean, regulated air at a fixed setting keeps clamping force consistent part after part.
Size the GFR series by stepping up through 200, 300, 400 and 600 as your required flow and port grow; this unit is already at the top of the range with a 1 in NPT port. Choose the drain to match the installation: differential-pressure (as fitted here) needs no operator attention, automatic suits unattended duty, and manual drain suits periodic maintenance rounds. Pick the 40 um standard element for general plant air, or specify the 5 um (W) grade where finer protection is needed. Gauge, scale (MPa, psi or bar) and thread (PT standard, G or NPT to order) are the remaining decode choices; a bracket is included.
Flow for this family is published as curves, not as a single rated figure, so we cannot quote one number here. Send us your application details and we will confirm the datasheet curve and sizing 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 GFR-series flow as curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote. Tell us your application and we will confirm the datasheet curve and check the sizing against your required flow before you order.
No. The N in GFR600C25NTK means no gauge is fitted on this configuration. Gauge options (embedded square gauge or external round gauge, with MPa, psi or bar scales) exist in the GFR range, so ask us if you want a gauged variant of this 1 in NPT filter regulator.
