The AirTAC GFR600C20JNTK AirTAC Filter Regulator NPT3/4 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 GFR600C20JNTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This size 600 unit carries a 3/4 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 element rises. A reverse/check valve is fitted, no pressure gauge is supplied, and no mounting bracket is included. The aluminium alloy bowl suits the larger 600 frame, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature range of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of drain type, 40 um or 5 um filtration, gauge options and G/NPT thread variants. Because flow is published as curves rather than a single rating, we confirm the datasheet and flow figures for your application on request.

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.

Dropping a 3/4 in branch off the plant air main to feed a production cell: the GFR600C20JNTK strips water and 40 um particulate from the supply and holds a steady regulated pressure for everything downstream.
On packaging and palletising lines with air-driven conveyor stops, clamps and diverters, the filter regulator keeps cylinder pressure consistent between shifts while the differential-pressure drain clears condensate without operator attention.
A test rig or laboratory bench running pneumatic fixtures and actuators needs clean, repeatable supply pressure; the fitted reverse/check valve holds the setting if upstream supply dips, and the 40 um element protects sensitive instruments.
Size 600 with a 3/4 in NPT port sits at the top of the GFR range, so step up or down through the 200/300/400/600 ladder to match the line size and the flow your circuit needs. The standard element is 40 um; choose the W option for 5 um if downstream valves or instruments need finer filtration. Drain is differential-pressure here; automatic (A) and manual (M) drains are available if you would rather have continuous bleed or a hands-on dump. A gauge can be added (round or square, with MPa, psi or bar scale) if you want a local setpoint reading - this unit ships without one. Thread is NPT on this code; PT is the AirTAC standard and G (BSPP) is also orderable. No bracket is fitted, so plan your own panel or bracket mounting.
One honest note before you order: AirTAC publishes flow as curves, not a single rated figure, so ask us to confirm sizing against your actual air demand before committing to a size.
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 number, so we do not quote a figure that is not in the datasheet. Send us your line size and air demand and we will confirm the flow-curve figures for this exact 3/4 in NPT unit on request before you order.
This code (N) is specified without a gauge, so no gauge is fitted as supplied. The GFR family accepts an embedded square gauge or an optional external round gauge with an MPa, psi or bar scale - tell us which scale you want and we will confirm the correct gauge-equipped variant for your application.
