The AirTAC GFR600C20MLC2 AirTAC 3/4 in Filter Regulator Low-Pressure 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 GFR600C20MLC2 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 has a 3/4 in PT port, a manual drain for periodic bowl emptying, and a standard 40 um filter element. The regulator is the low-pressure type; its exact setting range is not published in our data and we confirm it on request. An external round gauge with a psi scale is fitted so the setting can be read directly, the bowl on this size is aluminium alloy, maximum inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of manual, automatic or differential-pressure drain, 40 um or 5 um (W) filtration, gauge style and scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures 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.

Filtered, regulated air for the 3/4 in supply drops feeding case packers and actuator manifolds on a beverage bottling line, with a manual drain suited to a supervised shift schedule.
Conditioning the air feeding gate, stopper and diverter cylinders on a packaging conveyor, where a low set pressure is read directly off the fitted psi gauge.
Conditioning compressed air on a pilot-scale chemical process skid in a laboratory, keeping downstream control valves supplied at a stable low set pressure.
Step through sizes 200, 300, 400 and 600 to match the port and flow your line needs; this unit is size 600 with a 3/4 in PT port. Choose the drain: manual (this code) for periodic draining, automatic for continuous unattended condensate removal, or differential-pressure as the default. Filter grade is 40 um standard; specify W for a 5 um element. Gauge options are an embedded square gauge or an external round gauge with an MPa, psi or bar scale - this code carries a round psi gauge. Threads can be ordered in PT (standard), G (BSPP) or NPT, and a mounting bracket is included. Flow is published as curves, not a single rating, so ask us to confirm sizing against the 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, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
Manual drain means the bowl is emptied by hand on a routine schedule. If the unit runs unattended, order the automatic (A) or differential-pressure (blank) drain code instead; the filter grade can also be changed to 5 um with the W code.
