The AirTAC GFR60020MF3TK 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 GFR60020MF3TK is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air with a 40 um element, drains collected condensate by hand via the manual drain, and holds your set downstream pressure. This configuration has a 3/4 in NPT port, a manual drain, a reverse/check valve fitted, and an embedded square gauge reading in bar; the 600-size bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR line spans sizes 200 to 600 with port options from 1/8 in to 1 in, thread choices of PT (standard), G or NPT, drain types, 40 um or 5 um filtration, gauge styles and scales, and low-pressure variants. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet numbers 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.
| 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)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. 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.

Filtered, regulated air to workholding clamps and fixtures on machining centres, where the 3/4 in port serves a main drop feeding multiple clamp lines.
Clean, pressure-stable air for carton-forming cylinders and diverters on high-cycle packaging conveyors, with the check valve holding settings against backflow.
A point-of-use filter regulator at the head of an assembly or fabrication bench, conditioning the shop air supply before it reaches hand tools and actuators.
Size the unit by the port and flow step: 600 is the largest GFR size with a 3/4 in port, so step down to 300 or 400 if your line runs lighter. Choose the drain to suit access: manual (as here) needs someone to open the drain periodically; automatic or differential-pressure drains suit unattended installations. Pick 40 um for general air preparation or the W-code 5 um element where finer filtration is needed. Gauge scale is selectable (MPa, psi or bar - this unit is bar), and PT is the standard thread with G and NPT as order options; a mounting bracket is included.
Because flow is published as curves and not a single rated figure, send us your application details and we will confirm sizing against the datasheet 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 GFR flow as performance curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the relevant datasheet flow figures on request before you order.
The M in the code means condensate is drained by hand, which suits attended installations; automatic or differential-pressure drains are available on other codes for unattended use. The trailing K means a reverse/check valve is fitted, and F3 specifies the embedded square gauge with a bar scale.
