The AirTAC GFR60020MLC1TK AirTAC Filter Regulator NPT3/4 Low-Pressure is a genuine G-series filter regulator: water separation, 40 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 GFR60020MLC1TK 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 the low-pressure type with a 3/4 in NPT port, a manual drain bowl in aluminium alloy, the standard 40 um filter element, a round pressure gauge reading in MPa, and a built-in reverse (check) valve that holds downstream pressure if the supply drops. A mounting bracket is included.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of drain type, 40 um or 5 um filtration, gauge style and scale, thread option and low-pressure or standard regulation. Because flow is published as curves rather than a single rating, we confirm flow and 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. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.

Fixture clamps that must close at a controlled, moderate pressure get both clean air and an accurately set supply from one filter regulator mounted at the cell, with the check valve holding the clamp position if the main supply dips.
Packaging machines with cylinders, actuators and air jets run best on filtered, regulated air; a 3/4 in unit at the machine inlet conditions the whole supply, and the manual drain suits a line that is bled as part of shift housekeeping.
Where a production hall feeds low-pressure air rings, cooling headers or gentle blow-off points, this size 600 filter regulator cleans the air and holds the reduced pressure the process was set up for, with the MPa gauge giving operators a clear reference.
Size 600 with a 3/4 in port is the largest step in the GFR range, so start there when your line volume points to a bigger port - and ask us to confirm sizing against the flow curves before ordering. This unit is the low-pressure type, so verify the set pressure you need is within its range (we confirm the exact figure on request). Drain is manual here, meaning someone bleeds the bowl periodically; automatic or differential-pressure drains are available if you prefer not to. Filtration is the 40 um standard element; specify the W option for 5 um where finer protection matters. The round gauge reads in MPa; psi and bar scales and a square gauge are alternatives. Thread is NPT on this code, with G (BSPP) and PT available to order, and the mounting bracket is included.
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 characteristic curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and expected air demand and we will confirm the flow and sizing from the datasheet for this exact model before you order.
The M in this code specifies a manual drain: condensate collected in the aluminium bowl is released by operating the drain by hand, which suits installations checked on a regular schedule. If you would rather not rely on manual bleeding, the same size 600 unit can be ordered with an automatic drain or with the default differential-pressure drain.
