The AirTAC GFR600C20MLF1T AirTAC Filter Regulator NPT3/4 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 GFR600C20MLF1T 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 with a 3/4 in NPT port, a low-pressure type regulator, a 40 um standard filter element, a manual drain on the bowl, an embedded square gauge scaled in MPa, and a mounting bracket. The size-600 bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature of -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 that include automatic, manual or differential-pressure drains, a 5 um element (code W), gauge scale choices, G or NPT threads in place of the PT standard, and reverse/check valve variants. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for 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.

Conditioning the air feeding gripper and gate cylinders on a bottling line: the 40 um element strips water and debris before they reach the actuators, while the regulator holds a steady supply pressure so fill and capping motions stay repeatable.
Mounted ahead of a directional-valve manifold, the unit gives one filtered, regulated supply point for a whole valve stack, with the MPa-scaled square gauge giving the operator a visible setpoint at the machine.
Where a process loop runs at reduced pressure rather than full line pressure, the low-pressure type regulator in this unit is the matching choice; the 3/4 in NPT port suits the larger supply piping typical of such circuits.
Start with the port and size step: this unit is size 600 with a 3/4 in NPT port, the largest step in the GFR range, chosen when the air demand at the machine calls for the bigger ports. Because flow is published as curves and not as a single rated number, send us your application details and we will confirm sizing against the datasheet before you order. The drain choice matters in service: this unit has a manual drain, which means an operator drains the bowl on a routine; an automatic drain removes that task, and a differential-pressure drain is the catalogue default. The 40 um element fitted here is the standard grade; a 5 um element (code W) is available where finer filtration is required. The square gauge fitted is scaled in MPa; psi or bar scales and an external round gauge are options. NPT is the thread on this unit; the PT standard and G (BSPP) are the other catalogue thread options. A mounting bracket is included.
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. Send us your application details and we will confirm the flow and datasheet figures for this exact unit on request before you order.
This configuration is coded M for a manual drain: the bowl is drained by hand on a routine, which suits installations that are checked regularly. The catalogue also offers automatic (code A) and differential-pressure (blank, the default) drains on the GFR family if you would rather not rely on manual draining.
