The AirTAC GFR60020MLC2WTK 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 GFR60020MLC2WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This size 600 unit is built with a 3/4 in NPT port, a 5 um filter element (code W), a manual drain on the aluminium alloy bowl, and the low-pressure regulator type. A round pressure gauge scaled in psi is fitted, a reverse/check valve is installed, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um filtration, gauge and thread options, and standard or low-pressure regulation. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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.
| 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. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 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.

Feeding spray guns and air-activated agitators in a finishing booth: the 5 um element strips water and fine particles ahead of the gun while the low-pressure regulator holds a steady set point for consistent finish quality.
On a cartoning or wrapping line, the unit conditions the 3/4 in main feeding cylinder and actuator circuits, with the psi gauge giving operators a visible set point and the check valve holding downstream pressure if supply dips.
Installed at the drop to a machining centre's air-assist and clamping circuits: clean, regulated air for tool-change actuators, with the manual drain cleared during shift checks and the bracket fixing the unit to the frame.
Size and port set the air capacity: this unit is size 600 with a 3/4 in NPT thread (PT is the standard thread; G and NPT are order options). The 5 um element suits points where finer particulate removal matters; the 40 um standard grade remains available in the same size. The manual drain needs periodic operation, while automatic and differential-pressure drain variants are alternatives. Gauge scale (MPa, psi or bar) and the reverse/check valve are selectable, and a bracket can be ordered. Flow is published as curves, not 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 rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and required downstream flow and we will confirm the datasheet curve for this size 600, 3/4 in unit on request.
Code M specifies a manual drain: accumulated water in the aluminium alloy bowl is released by operating the drain by hand, which suits attended installations with regular checks. Automatic and differential-pressure drain variants are available in the same size if unattended drainage is preferred.
