The AirTAC GFR600C20JNWTK AirTAC Filter Regulator NPT3/4, 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 GFR600C20JNWTK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 3/4 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically when the pressure differential across the element rises, and a built-in reverse/check valve that holds downstream pressure when the upstream supply is lost. No gauge is fitted, so add a separate gauge if you need to read the regulated pressure. The aluminium alloy bowl on size 600 units suits demanding plant environments. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range with this drain type 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 is published in sizes 200, 300, 400 and 600 with 1/8 in to 1 in ports, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, gauge and bracket options, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, 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.

Installed at a 3/4 in branch drop feeding a packaging hall, the unit cleans the supply to 5 um and holds a steady regulated pressure to the distribution manifold, while the differential-pressure drain keeps condensate from travelling downstream.
Mounted ahead of the cylinder and valve bank on a conveyor drive section, the filter regulator removes water and fine particulate and sets the working pressure the actuators were designed for, with the check valve holding the circuit if supply pressure dips.
Fitted on the incoming air line to a CNC machining centre, the unit delivers filtered, regulated air to tool-changer and clamping circuits, and the 5 um grade suits the sensitive pneumatic components on the machine.
Step up or down through the GFR sizes (200/300/400/600) and port codes (1/8 in to 1 in) to match the air demand of the line: larger sizes carry larger ports and more flow, and flow is published as curves rather than one rated number, so send us your demand and we will confirm sizing from the datasheet. Choose the 5 um element (this code, suffix W) when downstream equipment needs finer filtration than the 40 um standard. The differential-pressure drain on this unit needs no operator attention; automatic and manual drains are available on other codes. Gauge, bracket and thread (PT standard, G or NPT to order) are also selectable, and this code carries a reverse/check valve and no gauge or bracket.
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 line demand and we will confirm the flow and sizing from the datasheet for this 3/4 in, size 600 unit before you order.
The N in the code means no gauge is fitted. You can order a GFR600 variant with the embedded square gauge (in MPa, psi or bar scale), fit an external round gauge, or use your own gauge downstream. The adjustment range with the differential-pressure drain is 0.15-0.9 MPa (20-130 psi).
