The AirTAC GFR60020MC3TK AirTAC Filter Regulator NPT3/4 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 GFR60020MC3TK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 3/4 in NPT port, a 40 um standard filter element, a manual drain on the aluminium alloy bowl, a round pressure gauge reading in bar, a built-in reverse/check valve, and a mounting bracket. The maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator set range is 0.05-0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C (non-freezing).
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. Options across the family include automatic, manual or differential-pressure drains, a 5 um (code W) element, square or round gauges with MPa, psi or bar scales, and G or NPT threads in place of the PT standard. Rated flow is published as curves rather than a single figure, so we confirm 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. |
| (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.

Installed at the drop feeding a machining centre's pneumatic clamps and tool-change cylinders, cleaning shop air of water and swarf-laden particulate and holding a steady set pressure for consistent clamping.
Mounted on the air preparation drop for a carton-forming conveyor section, delivering filtered air at a regulated pressure to the cylinders that push, hold and eject packs along the line.
Fitted ahead of air-operated process valves on a plant skid, conditioning the actuation air and setting the pressure the valve positioners and actuators see, with the check valve holding the line if upstream supply dips.
Size 600 with a 3/4 in port is the largest step in the GFR range, so start by matching the port and size to the air demand of the line; because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. This unit uses a manual drain, which suits installations where an operator can bleed the bowl at intervals; automatic and differential-pressure drains are available elsewhere in the family for unattended drops. The 40 um element is the standard grade, with a 5 um (W) option where finer filtration is needed. The gauge here reads in bar; square embedded gauges and MPa or psi scales are the other choices. Thread is NPT on this unit, with G 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 curves rather than a single rated figure, so we do not quote a number. Send us your line pressure, set pressure and air demand and we will confirm the flow from the datasheet on request before you order.
The M in the code specifies a manual drain: condensed water is released by operating the drain by hand. It suits installations where an operator is present at intervals. If the drop is unattended, the family also offers automatic (code A) and differential-pressure (blank) drains.
