The AirTAC GFR60020MLC2GK AirTAC Filter Regulator 3/4 in G 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 PT3/4" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60020MLC2GK is a size 600 filter regulator: one body that removes water and particulate from compressed air and holds a set downstream pressure. This configuration carries a G3/4 (3/4 in) G-thread port, a manual drain on the bowl, a 40 um filter element, and a round gauge reading in psi. It is the low-pressure regulator type, and a reverse/check valve is fitted. Maximum working (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, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um (W) filtration, gauge and thread options, and standard or low-pressure regulator types. The size 600 bowl is aluminium alloy. Flow is published as curves rather than a single rating, so ask us to confirm figures from 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Feeding filtered, regulated air to pneumatic clamps and vises on a machining cell, where chips and condensate upstream would otherwise reach the clamp cylinders and the set clamping pressure must stay steady from cycle to cycle.
Supplying the air cylinders that push, divert and stop cartons on a packaging conveyor, with water and pipe scale dropped out at the bowl and the actuator pressure held at the setting the mechanism was designed around.
Providing clean, regulated air to the positioners and actuators on pneumatically operated ball and butterfly valves, where a stable supply pressure keeps valve stroke timing consistent and the manual drain suits a supervised utility area.
Size 600 is the largest GFR frame with a 3/4 in port; step up or down in size to match the flow your circuit needs, and ask us to check the published flow curves against your application before ordering. Drain type is a real operating choice: this unit has a manual drain, which an operator bleeds periodically, whereas automatic and differential-pressure drains discharge condensate without attention. The 40 um element is standard; specify code W for 5 um where finer filtration matters. The round gauge fitted here reads in psi; MPa and bar scales are also available, and an embedded square gauge is the standard alternative. The G (BSPP) thread is a catalogue option - PT is the standard thread, with NPT also orderable. This is the low-pressure regulator type, so confirm your set pressure with us; a mounting bracket is included.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow 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 there is no one number we can honestly quote here. Send us your inlet pressure, set pressure and required flow, and we will confirm the sizing from the datasheet curves before you order.
The manual drain (code M) means an operator opens the drain to bleed accumulated condensate from the aluminium alloy bowl on a routine basis. The differential-pressure drain (the default) and the automatic drain (code A) discharge condensate without an operator. Choose manual where the unit is inspected regularly; choose automatic where it is not. The same bowl also means this size 600 unit is aluminium alloy rather than the polycarbonate used on sizes 200-400.
