The AirTAC GFR600C20MLJF2 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 AirTAC GFR600C20MLJF2 is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a 3/4 in PT port, a manual drain bowl so an operator empties collected condensate on a set schedule, and the standard 40 um filter element. It is the low-pressure regulator type, fitted with the embedded square gauge scaled in psi, and it ships without a mounting bracket. The size-600 bowl is aluminium alloy. 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 is offered in sizes 200, 300, 400 and 600 with a choice of ports, thread options (PT standard; G and NPT available to order), drain types, 40 um or 5 um filtration, gauge scales and bracket choices. Because flow is published as curves rather than a single rated figure, we confirm the exact flow and 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.

Mounted at the drop feeding carton-sealing and case-erector cylinders, this unit filters condensed water and pipe scale out of the shop air and holds a steady low regulated pressure so the cylinders stroke consistently through the shift. The manual drain is emptied during scheduled line housekeeping.
On a weaving floor where looms run on lower-pressure air, this low-pressure-type filter regulator sits at the branch feeding the machines, cleaning the supply and letting the setter dial in the working pressure while the psi gauge gives a direct local readout.
Fitted at the wall drop supplying a spray booth, the unit strips water and dirt that would otherwise blemish the finish and regulates the atomizing air to the setting the operator chooses, with the psi gauge confirming the set point at a glance.
Use the size and port step to match your line: this unit is size 600 with a 3/4 in PT port, the largest step in the GFR range, so size up from 300/400 when your circuit calls for the bigger connection. Choose the drain to suit access: this unit has a manual drain, which suits attended installations where an operator can bleed the bowl; automatic and differential-pressure drains are available on other codes where the unit is hard to reach. Filtration is the standard 40 um element; specify the W suffix if the application needs 5 um. The square gauge here reads in psi; MPa and bar scales, an external round gauge, G or NPT threads and a mounting bracket are all orderable options. Flow is published as curves, not a single rating, so ask us to confirm sizing against your 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 GFR600 series as performance curves rather than a single rated figure, so we do not quote one number. Send us your line pressure and the flow your application needs and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code means the condensate bowl is emptied by hand: an operator opens the drain at a set interval, which suits installations that are visited regularly. If the unit will sit in an inaccessible spot, GFR codes with an automatic or differential-pressure drain are available in the same size range - tell us the mounting situation and we will point you to the right variant.
