The AirTAC GFR60020MLF1T AirTAC Filter Regulator NPT3/4 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 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 GFR60020MLF1T is a size-600 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration is built for 3/4 in NPT ports, uses the standard 40 um filter element, and drains by hand through its manual drain, so an operator empties the aluminium alloy bowl on a routine walk-round. It is the low-pressure type and carries a factory-fitted embedded square gauge scaled in MPa for direct set-point reading.
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 including automatic or differential-pressure drains, a 5 um element (code W), psi or bar gauge scales, an external round gauge, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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.

On a stamping or forming cell running air cylinders at reduced pressure, this filter regulator cleans the shop air of water and scale, sets the working pressure for the press cycle, and gives the setter a square MPa gauge to read and lock the set point at the drop.
Pneumatic pushers, clamps and diverters on a packaging conveyor need dry air and a steady, gentle supply pressure to avoid product damage. This 3/4 in unit filters the line air and regulates it at the point of use, with the manual drain emptied during scheduled changeovers.
A pilot plant or test skid with pneumatic valves and actuators benefits from one body doing both jobs: the 40 um element stops particulate reaching the instruments, the low-pressure regulator holds a reduced supply for sensitive actuators, and the MPa gauge documents the setting.
Start with the port and size step: this unit is the 600 size with 3/4 in NPT threads, the largest step in the GFR range, so match it to your line's pipe size and let us confirm the flow curve against your demand before ordering. The manual drain suits attended installations where an operator can bleed the bowl regularly; if the unit will sit unattended, ask about the automatic or differential-pressure drain variants. The standard element is 40 um; specify the 5 um W option if downstream equipment needs finer filtration.
This is the low-pressure type, chosen where the working pressure sits below the standard regulator's range; the exact adjustment range for the low-pressure version is not published, so confirm it with us against your set point. The fitted square gauge reads in MPa, and psi or bar scales plus an external round gauge are order options. NPT is the thread on this code; G (BSPP) and PT are the other catalogue 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 GFR600 series as curves, not as a single rated number, so we do not quote a figure that is not in the datasheet. Send us your line pressure, set pressure and air demand, and we will confirm the flow from the datasheet curve for this exact 3/4 in configuration before you order.
The M in the code selects the manual drain: condensate collects in the aluminium alloy bowl and an operator opens the drain by hand. It is the right choice where the unit is visited routinely. If the regulator runs unattended, the automatic (A) or differential-pressure (blank) drain variants empty themselves, and the adjustment range also differs by drain type, so tell us your duty and we will confirm the right variant.
