The AirTAC GFR600C20MLF3T 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 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 GFR600C20MLF3T 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 NPT port, a 40 um standard filtration element, and a manual drain, so the bowl is emptied by hand as part of routine maintenance. It is the low-pressure regulator type and comes with an embedded square gauge scaled in bar, a metal bowl (size 600 bowls are aluminium alloy), and a mounting bracket included. 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 from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in. Within the family you can specify automatic, manual or differential-pressure drains, a 5 um element (code W) in place of the standard 40 um, gauge scale options, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Installed on a 3/4 in drop from the shop air main, it strips water and swarf-laden particulate before the air reaches tool circuits, and the low-pressure regulator holds a steady supply pressure to the workstations. The manual drain is emptied during daily walk-round checks.
Mounted ahead of a bank of directional control valves, it keeps moisture and particles out of the valve stack and gives the line a stable, manually adjustable supply pressure, with the bar-scale square gauge in view for setting and inspection.
Feeding fixture and clamp cylinders on a machine tool, the unit conditions the incoming air and lets the setter dial in the clamping pressure appropriate to the workpiece, with the included bracket securing the unit inside the cabinet.
Start with the port and size: this unit steps up to 3/4 in NPT in the largest GFR frame, the natural choice where a main line or high-consumption drop needs the 600-size body. Because flow is published as curves and not as a single rated figure, ask us to confirm sizing against your required flow before ordering. On drainage, this version uses a manual drain, which suits installations where someone is already walking the line; automatic and differential-pressure drains are available if you would rather not rely on manual blowdowns. The 40 um element is the standard grade; specify the W option for 5 um if downstream equipment needs finer filtration. The fitted square gauge reads in bar; MPa and psi scales and an external round gauge are alternatives. Thread is NPT here, with G (BSPP) and the PT standard available to order, and 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 this family as characteristic curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your line pressure and the flow your application needs, and we will confirm the sizing from the datasheet curves on request before you order.
The M in the code means the bowl is drained by hand: open the drain at the bottom of the bowl to discharge collected water as part of routine maintenance. If you would prefer the unit to discharge condensate without manual attention, automatic and differential-pressure drain versions are available in the GFR range - ask us and we will identify the right code.
