The AirTAC GFR60020MNWTK AirTAC Filter Regulator NPT3/4 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 GFR60020MNWTK is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air through a 5 um element (the fine grade, code W) and holds downstream pressure within a 0.05-0.9 MPa (7-130 psi) adjustment range. The 3/4 in NPT port suits larger supply lines, the manual drain lets an operator bleed collected condensate on a planned schedule, and the reverse/check valve holds downstream pressure if the upstream supply drops. No pressure gauge is fitted in this configuration, and the size-600 bowl is aluminium alloy with a mounting bracket included.
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 to 1 in, a choice of manual, automatic or differential-pressure drain, 40 um standard or 5 um fine filtration, gauge options and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 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.

| 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. |

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.

Point-of-use conditioning on the 3/4 in feed to a machining centre: the 5 um element protects directional valves from chips of scale and pipe rust while the regulator holds a stable setting for clamping and tool-change cylinders.
Mounted ahead of the cylinder bank on a case-erector and taping head line, where filtered, regulated air keeps stroke timing consistent through a full shift and the manual drain is bled at the end-of-shift checklist.
Dropping off a building compressed-air ring main to serve bench equipment and air-operated stirrers: the fine 5 um grade and steady regulated pressure suit instruments, and the check valve keeps settings intact during supply dips.
Choose GFR size by port and expected flow: this unit steps up to 3/4 in NPT for higher-demand lines, while 200/300/400 sizes cover smaller ports. Drain type is a real decision: manual (this unit) needs periodic operator draining; automatic and differential-pressure variants drain with less attention. This configuration carries the 5 um fine element; the 40 um standard grade is the default on other variants. No gauge is fitted here, and gauge scale options exist on variants that carry one. Thread is NPT on this code; PT is the catalogue standard and G (BSPP) is also available to order. A mounting bracket is included.
Because flow is published as curves and not a single rated figure, send us your application details and we will confirm sizing from the AirTAC datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes filter-regulator flow as performance curves rather than a single rated number, so no rated flow figure is quoted here. Send us your line pressure, downstream demand and allowed pressure drop, and we will confirm the sizing from the datasheet on request.
The M in the code selects the manual drain: condensate collected in the aluminium bowl is released by operating the drain when chosen, typically as part of a scheduled check. If you prefer unattended draining, the GFR600 family is also available with automatic or differential-pressure drain variants.
