The AirTAC GFR600C20LC1WTK 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 GFR600C20LC1WTK is an AirTAC GFR-series filter regulator: water and particulate removal plus pressure regulation combined in a single body. This size-600 unit carries a 3/4 in NPT port, a 5 um filter element (code W), and a differential-pressure drain, and it is built as the low-pressure regulator type (code L). A round MPa pressure gauge and a reverse (check) valve are fitted, the bowl at this size is aluminium alloy, and the 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 to 1 in, and options include 40 um standard or 5 um filtration, differential-pressure, automatic or manual drains, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet 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.

Feeds filtered, regulated air to the clamp cylinders on a pneumatic assembly press: the 5 um element protects seals and valves, while the low-pressure type suits circuits held at reduced downstream settings.
Mounted at the 3/4 in main drop feeding a packaging conveyor's air cylinders, removing condensed water and particulate from the shop air and regulating pressure to the actuators downstream.
Suits a test bench or process skid where compressed air must be cleaned and held at reduced pressure; the fitted check valve guards against backflow and the round MPa gauge gives a local pressure reading.
Size and port set the air capacity: step from 200 up through 300, 400 and 600 as your flow demand grows - this unit is the size-600 body with a 3/4 in NPT port. Choose the drain: differential-pressure (this unit), automatic, or manual. Choose the element: 40 um standard or 5 um (code W) for finer protection downstream - this unit carries 5 um. Gauges are embedded square as standard with an optional external round gauge in MPa, psi or bar scales; this unit has the round MPa gauge. Threads come as PT standard with G and NPT to order, and the bracket is included here (code J would delete it). The L in this code marks the low-pressure regulator type; its exact regulation range is not published in the catalogue, so confirm it with us. Flow is published as curves, not a single rated figure - ask us to check 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 rather than a single rated figure, so no one number is quoted here. Send us your line pressure and air demand and we will confirm the flow from the datasheet for this size-600, 3/4 in unit before you order.
It marks the low-pressure regulator type. The standard GFR adjusts over the published regulation range, while the low-pressure type is intended for reduced downstream settings; its exact range is not published, so confirm it with us. The rest of the code decodes as 3/4 in NPT port, 5 um element, differential-pressure drain, round MPa gauge, check valve fitted and bracket included.
