The AirTAC GFR600C25LNTK AirTAC Filter Regulator 1 in NPT Low-Pressure 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 GFR600C25LNTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body, sized for a 1 in NPT line. This configuration is the low-pressure type with a 40 um standard filter element, a differential-pressure drain, a reverse/check valve fitted, a mounting bracket included, and no gauge supplied. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The size 600 bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, optional 5 um filtration (code W), automatic or manual drain choices, G and NPT thread options, and gauge choices on regulator-equipped units. 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.

Feeds filtered, regulated air to clamping cylinders on a machining fixture where the workholding circuit runs at reduced pressure and condensate or chips must be kept out of the downstream valves.
Supplies cleaned, regulated air to blow-off nozzles clearing dust and film from packs moving along a conveyor, with the fitted check valve holding the set pressure against backflow.
Regulates low-pressure atomizing air to spray guns or coating lines where a stable, filtered supply protects finish quality and the 40 um element stops particulate reaching the gun.
Size steps up through the GFR range from 200 to 600, with ports from 1/8 to 1 in - pick the step that matches your line's flow demand and existing piping; this unit is the size 600 with a 1 in NPT port. Drain choice is differential-pressure (the default), automatic (A) or manual (M); filter grade is 40 um standard or 5 um with the W code. Gauge and scale options apply to regulator-equipped units, though this code specifies no gauge. Thread is PT as the standard, with G and NPT as order options, and a bracket is included. Flow is published as curves, not a single rating, so 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 the GFR series as curves rather than a single rated figure, so there is no one rated-flow number to quote. Tell us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The L code marks the low-pressure regulator variant, intended for circuits set below the standard range. The exact adjustment range for this variant is not published in our sheet, so ask us to confirm it on request. This code also carries a reverse/check valve (K), a 40 um element, and a differential-pressure drain.
