The AirTAC GFR60020MLNT AirTAC Filter Regulator NPT 3/4 in 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 GFR60020MLNT is a 600-size filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration has NPT 3/4 in ports, a manual drain bowl in aluminium alloy, and the standard 40 um filter element. It is the low-pressure type, intended for circuits where regulated pressure stays below the standard regulator's range; the exact adjustment window for the low-pressure version is not published, so confirm it against your setpoint before ordering. No gauge is fitted (code N) and a mounting bracket is included.
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, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drain, a 5 um element option (code W), and gauge or no-gauge variants. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing 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. 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.

|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Air-prep point for clamp and fixture cylinders on a CNC machining cell, where the low-pressure regulator holds a gentle clamping force and the 40 um element keeps scale and pipe debris out of the clamp valves.
Feeding air cylinders and diverters on a carton packaging or palletising line, with the manual-drain bowl bled during scheduled changeover stops and the 3/4 in NPT ports matching the line's main drop.
Low-pressure regulated air for tension rollers, guide cylinders and blowing nozzles on textile or paper converting machinery, where the filter section removes water carried over from the compressor ring main.
Start with the size and port: the 600 frame with 3/4 in NPT ports is the larger step in the GFR range, so match it against the air demand of the circuit. Because flow is published as curves and not a single rating, ask us to confirm the sizing against your application before ordering. This unit is the low-pressure type, so verify your regulated setpoint falls in its range - we will confirm the figures on request. Drain is manual here: you bleed the bowl by hand, which suits installations that are checked routinely; automatic or differential-pressure drain variants exist if you cannot guarantee that. The fitted element is the standard 40 um grade; specify 5 um (code W) if downstream equipment needs finer filtration. No gauge is fitted, so add one separately if operators need to read the downstream pressure. Thread is NPT on this unit; PT is the catalogue standard and G is also available. 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 performance curves rather than a single rated figure, so there is no one number we can honestly quote. Send us your line pressure, regulated setpoint and the air demand of your equipment, and we will confirm the sizing from the datasheet on request.
The M in the code selects a manual drain: condensed water collects in the aluminium bowl and is released by hand, which suits installations inspected on a routine schedule. The L in the code makes it the low-pressure regulator type, intended for circuits with lower regulated setpoints than the standard version; its exact adjustment range is not published, so confirm it with us before ordering.
