The AirTAC GFR600C20MJNWTK AirTAC Filter Regulator NPT3/4 5um 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 GFR600C20MJNWTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This 600-size unit carries a 3/4 in NPT port, a 5 um filter element (the W grade, finer than the 40 um standard), a manual drain on the aluminium alloy bowl, and a built-in reverse/check valve. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi). No gauge is fitted, so add one if you want visual pressure setting; no mounting bracket is included.
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, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um filtration, gauge options, and PT, G or NPT thread variants. 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.

Mounted at the drop to a spray-booth manifold, this unit strips water and fine particulate from the shop air line and holds a steady regulated pressure to the paint supply, with the manual drain bled at shift start.
Feeding the cylinders and grippers on a case-sealing conveyor, the 3/4 in port carries the line volume while the regulator holds consistent actuator pressure; the check valve backs up the downstream circuit.
Installed ahead of the directional valves on a pneumatic forming press, it delivers filtered, regulated air to the valve stack, with the 5 um element protecting spool clearances from fine contamination.
Step up through the GFR sizes (200, 300, 400, 600) as your port and air demand grow; this 600-size unit takes a 3/4 in NPT port. Choose the drain to match maintenance access: manual (as here) for periodic bleeding, automatic or differential-pressure where the unit is hard to reach. Pick the 5 um W element when downstream equipment needs finer filtration than the 40 um standard, and decide whether you want a gauge fitted for setting the regulator. PT is the standard thread; G and NPT are order options. 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, not as a single rated figure, so we do not quote a number. Send us your line pressure, downstream pressure target and air demand, and we will confirm the flow figures from the datasheet for your application.
The manual drain means someone opens the bowl drain periodically to expel collected water, which suits attended installations; automatic or differential-pressure drains suit unattended lines. With no gauge fitted, you set the regulator blind - if you want visual setting, order a variant with a gauge or add an external one.
