The AirTAC GFR60020MF2TK 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 GFR60020MF2TK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size-600 configuration is specified with 3/4 in NPT ports, a 40 um standard filter element, a manual drain bowl in aluminium alloy, an embedded square gauge reading in psi, a fitted reverse/check valve, and a mounting bracket. The manual drain means an operator opens the bowl drain to discharge collected condensate, which suits installations visited on a regular maintenance round.
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 differential-pressure, automatic or manual drains, an optional 5 um element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, 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. 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.

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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 branch off the factory air main to deliver cleaned, regulated air to a production bay, with the manual drain bled during the daily walk-round.
Feeding the air supply to a CNC machining centre, where the 40 um element strips water and pipe scale and the regulator holds a steady setting for clamping and tool-change circuits.
Conditioning the supply to pneumatic cylinders and valves on a carton-forming packaging line, with the psi gauge giving operators a local setpoint readout at the machine.
Start with the port step: this unit is size 600 with 3/4 in NPT ports, the largest step in the GFR range, so size up or down (200/300/400/600) against the air demand of the circuit. Choose the drain to match your maintenance routine: manual (this unit) needs a scheduled drain visit, automatic drains itself, and the default differential-pressure drain bleeds when the pressure differential rises. Filter grade is 40 um standard here; specify 5 um (code W) where finer particulate protection is needed. The gauge is the embedded square type reading psi; external round gauges and MPa or bar scales are available. Thread is NPT on this code; PT is the catalogue standard and G is also an order option. A bracket is included, and the K code adds a reverse/check valve.
Because flow is published as curves and not a single rated figure, we cannot quote one number honestly. Send us your application details and we will confirm sizing against the datasheet curves before you order.
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 GFR600 series as curves, not as a single rated figure, so we do not quote a number. Tell us your working pressure and air demand and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code specifies a manual drain bowl: an operator opens the drain to discharge collected condensate, which suits lines visited on a fixed maintenance schedule. If you want the bowl to drain itself, the same size is available with an automatic drain (code A) or the default differential-pressure drain - ask us to quote the variant.
