The AirTAC GFR600C25LJNTK AirTAC Low-Pressure Filter Regulator NPT 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 GFR600C25LJNTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single 600-size body with a 1 in NPT port. This configuration is the low-pressure type, fitted with a reverse/check valve (code K) and no mounting bracket (code J). It carries the standard 40 um filter element and a differential-pressure drain, and the 600-size bowl is aluminium alloy. No pressure gauge is fitted on this code (N), so add a gauge separately if the panel needs a local reading.
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, a choice of differential-pressure, automatic or manual drain, an optional 5 um element (code W), and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Feeding clamping cylinders and fixture actuators on a machining cell, where the low-pressure regulator type holds a reduced working pressure downstream of the 40 um element and the check valve helps hold the set circuit.
Conditioning the air feed to carton-forming and case-sealing stations on a packaging conveyor, removing condensed water and particles before the air reaches the machine's directional valves and cylinders.
Filtering and regulating the supply air to spray guns and atomising stations in a paint or coating line, where clean, moisture-reduced air at a controlled low pressure is required at each gun position.
Step up or down through the GFR sizes (200/300/400/600) so the port and body match the air demand of the circuit; this unit is the largest step, with a 1 in NPT port for high-consumption lines. Choose the drain: differential-pressure (this unit, the default), automatic (A) for unattended dumps, or manual (M) where an operator drains on schedule. Filtration is 40 um as standard here; specify the W code if a 5 um element is needed. Gauges are optional - this code has none - and threads can be ordered as PT (standard), G or NPT; brackets are optional on GFR, and this code omits one.
Because flow is published as curves and not as a single rated figure, send us your application details and we will confirm the sizing against the datasheet 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and sizing against the datasheet before you order.
No. The N code in GFR600C25LJNTK means no gauge is fitted. Gauges are an option on GFR units (round or square, with MPa, psi or bar scale), so tell us if you need one added and we will quote the correct code.
