The AirTAC GFR600C20MF1WTK 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 GFR600C20MF1WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This size 600 unit is built for a 3/4 in NPT port and carries a 5 um filter element (code W), a manual drain on the aluminium alloy bowl, an embedded square gauge scaled in MPa, and a reverse/check valve. The standard regulator adjusts from 0.05 to 0.9 MPa (7-130 psi) with the manual drain, 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 spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options including 40 um standard or 5 um filtration, differential-pressure, automatic or manual drains, square or external round gauges with MPa, psi or bar scales, a reverse/check valve, and G (BSPP) or NPT threads in place of the PT standard. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Filtered, regulated air to spray booths and air-driven applicators, where the 5 um element helps keep water and particles out of the finish and the square MPa gauge lets operators set and watch line pressure.
Feeding pneumatic cylinders and grippers on a carton-forming conveyor, with the regulator holding a steady setting as actuators cycle and the fitted check valve in the air path.
Supplying filtered, regulated air to quarter-turn pneumatic valve actuators on process skids, where the 3/4 in port suits actuator supply lines and the manual drain suits attended compressor rooms.
The real choices on this family: step the size and port to match required flow (200 through 600, 1/8 to 1 in); pick the drain - differential-pressure (default), automatic, or manual as coded here; choose 40 um standard or 5 um fine filtration (this unit carries W, 5 um); select the gauge and its scale (MPa, psi or bar); and order G (BSPP) or NPT thread where PT is not wanted. A mounting bracket is included with this unit. Flow is published as curves, not a single rating, so send us your flow and pressure requirements 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your flow and pressure requirements and we will confirm the datasheet curve and sizing for this 3/4 in unit on request.
This unit is coded M for a manual drain: someone opens the drain to expel collected water from the bowl. It suits attended installations where bowls are checked as part of a routine; for unattended duty, ask about the automatic or differential-pressure drain versions. Note that with a manual drain the regulation range is 0.05-0.9 MPa (7-130 psi).
