The AirTAC GFR600C20MLF2T 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 GFR600C20MLF2T is an AirTAC GFR600 filter regulator: a single body that removes water and particulate from compressed air and then regulates the downstream pressure. This size 600 unit is fitted with a 3/4 in NPT port, a manual drain, the standard 40 um filter element, the low-pressure regulator type and an embedded square gauge scaled in psi. The bowl on size 600 units is aluminium alloy, a mounting bracket is included, the maximum inlet pressure is 1.0 MPa (145 psi), and the operating 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 that include automatic, manual or differential-pressure drains, a 5 um filter element (code W), MPa, psi or bar gauge scales, and G or NPT threads in place of the PT standard. AirTAC publishes flow for this family as curves rather than a single rated figure, so ask us to confirm the flow and datasheet figures for 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.

On a process line, this unit sits ahead of air-actuated control valves and positioners, dropping header pressure to the lower setting the actuator needs - the low-pressure regulator type suits circuits running well below line pressure - while keeping rust and water out of the instrument air.
Feeding pneumatic clamps and tool-change cylinders on a machining centre, this filter regulator removes moisture and pipe scale from the shop air and holds a steady reduced pressure so clamp force does not wander between cycles.
On a carton-sealing or case-packing conveyor, this unit supplies the pusher and flap-fold cylinders with clean, regulated air, and the manual drain on the aluminium bowl is emptied during scheduled line maintenance.
Every meaningful choice in this family is decodable from the code. Step through sizes 200/300/400/600 to match the port and the flow your line needs - larger sizes carry larger ports and more flow, and the published curves (not a single rating) define exactly how much. Drain type matters: this unit has a manual drain, so condensate is released by hand at intervals; automatic and differential-pressure drains are available where that is not practical. The 40 um element is standard, and a 5 um element (code W) suits applications needing finer filtration. The gauge here is the embedded square type scaled in psi; MPa and bar scales, and an external round gauge, are options. Thread: PT is the AirTAC standard, with G (BSPP) and NPT as order options - this unit is NPT. A mounting bracket is included. Because flow is published as curves rather than one rated number, 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 family as curves rather than a single rated figure, so there is no one number we can quote. Tell us your supply pressure, downstream setting and air demand, and we will confirm the flow for the GFR600 from the datasheet on request.
The M in the code sets the manual drain: condensate collected in the aluminium bowl is released by hand at intervals, which suits lines with routine maintenance visits. If nobody is available to drain it, the same size is available with an automatic or differential-pressure drain - ask us for that variant.
