The AirTAC GFR60020MC3WTK AirTAC Filter Regulator 3/4 in NPT 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 GFR60020MC3WTK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 5 um filter element (code W), a manual drain on the aluminium alloy bowl, a round pressure gauge scaled in bar, a built-in reverse/check valve, and a 3/4 in NPT port. The maximum working (inlet) pressure is 1.0 MPa (145 psi), the regulator adjustment range is 0.05-0.9 MPa (7-130 psi), and the operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of port sizes, PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge style and scale, and a reverse/check valve option. Flow is published as curves rather than a single rating, so we confirm flow and datasheet figures 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. 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.

|---|---|
| 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)). |
| (blank) | Standard 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. |
| 3 | Gauge scale: bar. 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.

Installed at a 3/4 in plant air drop, it cleans the supply to 5 um and holds a set working pressure for the air tools and cylinders used at an assembly cell, with the check valve holding the setting if the main supply dips.
Feeding a bank of directional valves and actuators on a machine, it removes water and fine particulate before the valves and lets the technician dial in the exact working pressure on the bar gauge.
On a packaging or conveyor line with air cylinders and blow-off points, it conditions the 3/4 in supply in one body, and the manual drain lets maintenance bleed collected water during scheduled rounds.
Size 600 is the largest step in the GFR range, with the largest port in this code: 3/4 in NPT. Choose the size and port against the flow your line needs, and match the thread to your piping - PT is the standard, with G (BSPP) and NPT as order options. The manual drain here suits installations where an operator can bleed the bowl on a routine; choose automatic or differential-pressure drain codes if the unit will sit unattended. The 5 um element (W) is the finer of the two published grades (40 um is standard) - pick it where downstream valves and instruments need cleaner air. The round bar gauge and the reverse/check valve are already fitted, and the mounting bracket is included.
Because flow is published as curves rather than a single rated figure, 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 against the datasheet curves whether this 3/4 in, size-600 unit is correctly sized before you order.
The M code specifies a manual drain: someone bleeds the aluminium alloy bowl by hand, which suits attended installations on a maintenance routine; automatic and differential-pressure drain codes exist for unattended setups. The W code specifies the 5 um element, the finer of the two published filtration grades - the standard grade is 40 um - so this unit delivers cleaner air to sensitive downstream components.
