The AirTAC GFR600C20NWTK AirTAC Filter Regulator NPT 3/4 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 GFR600C20NWTK is an AirTAC GFR-series filter regulator: water and particulate removal plus downstream pressure regulation combined in a single body. This size-600 unit is built for 3/4 in NPT ports and carries the W filter grade, so air passes through a 5 um element before reaching the regulator. It uses a differential-pressure drain, has no gauge fitted, and includes a reverse/check valve. At size 600 the bowl is aluminium alloy, and a 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, filter grades of 40 um (standard) or 5 um (W), differential-pressure, automatic or manual drains, gauge options, and G or NPT thread variants beside the PT standard. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us and we will 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.

A point-of-use filter regulator on the 3/4 in drop feeding a machining center's pneumatic clamps and valves. The 5 um element strips water and particulate before the regulator holds the set pressure downstream.
Filtered, regulated air for the cylinder banks on a bottling conveyor. The differential-pressure drain sheds accumulated condensate, and the fitted check valve helps hold the downstream setting if supply pressure dips.
Conditioning the shop-air line that feeds spray equipment in a paint booth. The 5 um element reduces water and particulate carryover ahead of the regulator, which sets a stable supply pressure at the gun.
Size and port set the capacity step: this unit moves up to size 600 with 3/4 in NPT ports for higher-demand circuits. The drain here is differential-pressure, which bleeds condensate as the pressure differential across the element rises; automatic (A) and manual (M) drains are catalogue alternatives. The W code selects the 5 um element over the standard 40 um. Gauge codes (round external or embedded square, with MPa, psi or bar scales) and the reverse/check valve (K, fitted here) are further decodable choices, as is thread: PT is the AirTAC standard, with G and NPT as order options. Because flow is published as curves rather than a single rating, send us your demand figures and we will confirm 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 GFR flow as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and demand, and we will confirm the relevant datasheet flow figures for you before you order.
The N in the code means no gauge is fitted. Gauges are a catalogue option on GFR units: an embedded square gauge or an external round gauge, each available with MPa, psi or bar scales. If you want a gauge, order a variant with the appropriate gauge code.
