The AirTAC GFR60020MLNWT AirTAC Filter Regulator NPT 3/4 in, 5 um is a genuine G-series filter regulator: water separation, 5 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 GFR60020MLNWT is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 3/4 in NPT port, a 5 um filter element (the finer of the two published grades), a manual drain for supervised bowl draining, and an aluminium alloy bowl, which is the material used at size 600. It is a low-pressure type regulator, supplied without a gauge, 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, and is offered with manual, automatic or differential-pressure drains, 40 um or 5 um elements, gauge options and PT, G or NPT threads. Because flow is published as curves rather than a single rating, we confirm flow and other datasheet figures on request before you order.

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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 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. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

Feeds filtered, regulated air to the tool-changer and clamping circuits of a machining centre, with the 5 um element protecting fine valve internals from particulate carryover.
Supplies regulated air to the gripper and pusher cylinders on a bottling line, where the manual drain suits a line that is already stopped for scheduled cleaning and inspection.
Prepares air for the diverters and stop-gate cylinders along a packaging conveyor, combining water and particle removal with a stable pressure setting in one 3/4 in unit.
Size 600 with a 3/4 in NPT port is the largest step in the GFR range, so start here when the line serves several actuators or a high-demand machine; smaller sizes (200/300/400) step down in both port and capacity. The 5 um element in this unit suits air that feeds sensitive components; the standard 40 um grade is the choice for general shop-air protection. The manual drain means an operator opens the bowl drain during routine checks - choose automatic or differential-pressure drain instead if the installation is unattended. No gauge is fitted; gauge and scale options can be selected if a local pressure reading is needed. PT is the standard thread, with G and NPT as order options - this unit is specified with NPT. A mounting bracket is included.
Flow for this family is published as curves, not a single rated figure, 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 there is no one rated flow number we can quote. Send us your application details and we will confirm the flow and sizing from the datasheet on request.
The M in the code specifies a manual drain: the bowl is drained by hand during routine maintenance, which suits attended installations. The N specifies that no gauge is fitted; a gauge with your preferred scale can be selected as an option if you want a local pressure reading.
