The AirTAC GFR600C25JNTK 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 GFR600C25JNTK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single compact body. This size 600 unit is fitted with a 1 in NPT port, the standard 40 um filter element and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the bowl rises. The K code adds a built-in reverse (check) valve, and the N code means no pressure gauge is supplied. At this size the bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 0.15-0.9 MPa (20-130 psi), and the working 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 ports from 1/8 in to 1 in, and can be ordered with automatic or manual drain, a 5 um (W) element, a round or square gauge in MPa, psi or bar scale, G (BSPP) or NPT thread in place of the PT standard, and with or without a mounting bracket. 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.

Point-of-use conditioning at the paint booth: water and grit are stripped from the shop air line and the atomizing pressure fed to the spray guns is held steady, protecting finish quality on the line.
Feeding the directional control valves on a stamping or forming press, where the 1 in NPT port matches the main air drop and the check valve holds the downstream circuit if the upstream supply is interrupted.
Regulated, filtered air for the cylinder-driven pushers and sorting gates on a packaging conveyor, keeping actuator speeds consistent as the header pressure wanders through the shift.
Start with the port and size step: GFR comes in sizes 200, 300, 400 and 600, covering 1/8 in to 1 in ports, and the right step depends on the air demand of the circuit it feeds - this 600 unit with its 1 in NPT port sits at the top of the range. Choose the drain next: differential-pressure (this unit) drains on load changes, automatic (A) drains on a timed cycle, and manual (M) needs an operator to open it. Filter grade is 40 um standard or 5 um with the W code if finer protection is needed. Gauges are optional (this unit ships without one), and thread can be PT (standard), G or NPT - this unit is NPT. A mounting bracket is optional (J = none fitted here). Flow is published as curves, not a single rating, so please 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 performance as curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
No. The N code in GFR600C25JNTK means no gauge is supplied. Gauges are orderable options on GFR units - an embedded square gauge or an external round gauge, in MPa, psi or bar scale - so ask us to quote the version you want if you need a gauge on the regulator.
