The AirTAC GFR600C20MLJF2W AirTAC Filter Regulator PT3/4, 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 GFR600C20MLJF2W is an AirTAC GFR-series filter regulator: water-and-particulate filtration and pressure regulation combined in one body. This size 600 unit has a 3/4 in PT port, a 5 um filter element (the fine option; 40 um is the standard grade), a manual drain on the aluminium alloy bowl, and a low-pressure regulator fitted with an embedded square gauge reading in psi. No mounting bracket is included and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi); working temperature 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 in to 1 in, and options for thread (PT standard; G and NPT to order), drain type, filter grade, gauge scale and bracket. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures 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.

On a CNC fixture line, this unit filters the plant air to 5 um and holds a set low regulated pressure to the clamp cylinders, with the square psi gauge giving the operator a local pressure readout at the fixture.
Ahead of the nozzles that blow water off bottles passing a conveyor, this filter regulator removes condensate and particulate at the air drop and sets the supply pressure to the blow-off manifold; the manual drain is emptied during shift checks.
Quarter-turn pneumatic actuators on a process skid need clean air at a stable set pressure: this unit filters the plant supply to 5 um and regulates it to the actuator rating, with the 3/4 in PT port matching the skid air header.
Choose size and port by the air demand of the line downstream: size 600 with a 3/4 in PT port is the largest step in the GFR range, and the bigger body keeps pressure drop lower at high demand. Pick the drain to suit access: manual (this unit) needs periodic draining by hand, while automatic and differential-pressure drains handle condensate for you. The 5 um element (code W) suits finer downstream needs; 40 um is the standard grade. The embedded square gauge here reads psi, with MPa and bar scales and an external round gauge as alternatives. Thread is PT as standard, with G (BSPP) and NPT available to order, and a bracket can be added if panel mounting is needed. Because flow is published as curves, not a single rating, send us your demand 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 downstream air demand and working pressure and we will confirm the datasheet curve and sizing for this 3/4 in unit on request.
This unit's code specifies a manual drain: condensate collected in the aluminium alloy bowl is released by hand at intervals. The same series is also available with automatic or differential-pressure drains if you would rather not rely on manual draining; ask us for the alternative model code.
