The AirTAC GFR600C20LNWTK AirTAC Filter Regulator 3/4 in NPT 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 GFR600C20LNWTK is a size 600 filter regulator: water and particulate filtration plus pressure regulation combined in one body, with a 3/4 in NPT port. This configuration carries the 5 um filter element (code W) for finer particle removal than the standard 40 um grade, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough, and the low-pressure regulator type (code L) for circuits that need a lower set-pressure band. No gauge is fitted (code N), a reverse/check valve is fitted (code K) to hold downstream pressure if the supply side drops, and the mounting bracket is included. At size 600 the drain bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT (standard), G and NPT threads, with a choice of drain type, filter grade, gauge and scale, and with or without a check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure against 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.

Point-of-use conditioning at paint-line air drops: the 5 um element removes fine particles that would spoil finish work, the regulator holds a steady low set pressure to the application equipment, and the check valve keeps the drop from losing its setting if the main header dips.
Feeding conditioned air to cylinders and actuators on packaging and case-sealing conveyors: filtered, regulated supply at a 3/4 in port serves larger machines, while the differential-pressure drain keeps condensate from carrying downstream into the mechanism.
Supplying pilot air to pneumatically actuated process control valves, where the low-pressure regulator type holds the lower set pressures such positioners and pilots need and the 5 um grade protects sensitive pilot internals from particulate.
Start with the port step: this unit is size 600 with a 3/4 in NPT port, the largest step in the GFR range, so match it to your line size and the flow your circuit needs - we can check the published flow curves against your demand on request. Choose the drain: differential-pressure (this unit, automatic in operation), fully automatic, or manual, where someone drains the bowl as part of a routine. Choose the element: 40 um standard or 5 um (code W, fitted here) where finer protection is needed downstream. Decide on a gauge - this unit ships without one (code N), and gauge scale options exist where a gauge is specified. Thread is NPT here; PT is the catalogue standard and G is also an order option. The low-pressure regulator type (L) suits circuits needing a lower set-pressure band - ask us to confirm the exact range for this type. A bracket is included with this configuration.
One honest note on sizing: AirTAC publishes flow for this family as curves, not a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the right size 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 family as curves, not as a single rated figure, so we do not quote a flow number for this unit. Send us your application details - line size, downstream demand and set pressure - and we will confirm the flow data from the datasheet and check the sizing with you before you order.
The N in the code GFR600C20LNWTK means no gauge is fitted (code N). GFR units can be ordered with an embedded square gauge or an optional external round gauge, with MPa, psi or bar scales, so if you want a local pressure reading at this regulator we can quote the equivalent configuration with a gauge included.
