The AirTAC GFR60020MLNWTK AirTAC Filter Regulator NPT3/4, 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 GFR60020MLNWTK 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 for 3/4 in NPT ports, carries the fine 5 um filter element (code W), drains by hand through the manual drain, and is the low-pressure type (code L) for circuits that operate well below standard line pressures. A reverse/check valve (code K) is fitted, no gauge is supplied, and the aluminium alloy bowl reflects the size-600 construction.
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, a choice of drain types, 40 um or 5 um filtration, gauge options and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the figures against your application before ordering.

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. |
| K | Reverse-flow (reflux) valve fitted. |
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 forming or assembly press that runs its air cylinders at reduced pressure, this filter regulator cleans the supply and holds the setpoint, with the check valve holding the downstream circuit if upstream pressure is lost.
Test benches and lab rigs that need clean, finely controlled air at low pressure use the 5 um element to protect instruments and the low-pressure regulator type for gentle setpoint control at the bench.
Bag-sealing and tray-sealing stations on packaging lines run actuated clamps and seals at moderate pressures; this unit filters the shop air to 5 um and regulates the station circuit, with manual drain during shift checks.
Start with the port step: size 600 with 3/4 in NPT ports sits at the top of the GFR range, so match it to the line size and the flow your circuit needs. Choose the drain to suit access: manual drain (as here) means an operator opens the bowl drain, an automatic drain needs no attention, and the differential-pressure default drains on a pressure drop. Pick the 5 um element (code W) where downstream equipment needs finer filtration than the 40 um standard. Note that no gauge is fitted in this configuration; gauge and scale options exist if you want a visual pressure reference. The low-pressure type (L) is the right choice only for circuits running at reduced pressures - confirm the working band with us. Thread is NPT here; PT is the standard and G is also an order option. Bracket included. Because flow is published as curves rather than a single rating, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves, not as a single rated number, so we do not quote a figure here. Tell us your line pressure and the flow your application needs and we will confirm the sizing from the datasheet before you order.
The M in the code selects the manual drain: an operator opens the bowl drain to expel collected water, which suits installations checked on a regular schedule (automatic and differential-pressure drains are available on other codes). The N means no gauge is fitted; gauge and scale options exist if you want a visual reference. The L code marks the low-pressure regulator type, and the K code means a reverse/check valve is fitted.
