The AirTAC GFR60020MLC3T AirTAC Filter Regulator 3/4 in NPT 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 GFR60020MLC3T is a size 600 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration carries a 3/4 in NPT port, a 40 um standard filter element, a manual drain on the bowl, and a low-pressure regulator type. The bowl on size 600 units is aluminium alloy, and an external round gauge with a bar scale is fitted so the set pressure can be read at a glance. 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 port sizes from 1/8 in to 1 in, and options include automatic or manual drains, a 5 um element (code W), gauge style and scale, G or NPT threads in place of the PT standard, and bracket choices. Because flow is published as curves rather than a single rated figure, we confirm the datasheet and sizing 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. 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.

Installed at the 3/4 in main drop feeding a packaging hall, this filter regulator removes water and pipe scale from the compressed air and lets maintenance set a stable low regulated pressure for the hall's actuators, with the bar-scale gauge giving a local reading at the drop.
Mounted on the supply line to the air cylinders that index and stop a conveyor system, the unit filters condensate and particulate from the plant air and holds the downstream pressure the cylinder circuit was designed around; the manual drain lets the shift operator bleed the bowl during scheduled checks.
Used by a machine builder as the front-end air preparation stage on an OEM machine panel, the combined filter and regulator in one body saves panel space at the 3/4 in inlet, and the included mounting bracket fixes the unit to the panel alongside the other preparation components.
Step up or down through the GFR sizes (200/300/400/600) so the port and body match the flow your line needs - this unit is the size 600, 3/4 in NPT step. Choose the drain to suit maintenance: manual drain (fitted here) needs an operator to bleed the bowl, automatic drain bleeds itself, and the differential-pressure default drains on a pressure drop. The 40 um element is the standard grade; specify 5 um (code W) where finer particulate removal matters. Gauge style and scale (MPa, psi or bar - this unit ships with a round bar-scale gauge), thread family (PT standard, G or NPT to order) and the included mounting bracket complete the decode. Flow for this family 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 GFR family as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and we will confirm the flow and sizing figures from the datasheet on request before you order.
The M in the code GFR60020MLC3T specifies a manual drain, meaning an operator opens the drain to bleed collected water from the bowl. AirTAC also offers an automatic drain (code A) that drains without operator action, and a differential-pressure drain as the default; choose the type that matches your maintenance routine.
