The AirTAC GFR60020MLF3T 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 GFR60020MLF3T is a size-600 GFR filter regulator: water and particulate filtration plus pressure regulation combined in a single body, sized for 3/4 in NPT ports. This configuration carries the standard 40 um filter element, a manual drain on the bowl, the low-pressure regulator type, and an embedded square gauge reading in bar. The size-600 bowl is aluminium alloy, and a mounting bracket is included. Maximum working (inlet) pressure is 1.0 MPa (145 psi), with an operating temperature range of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT, G or NPT threads, differential-pressure, automatic or manual drains, a 5 um element option, gauge and scale choices, and a reverse/check valve option. Flow is published as curves rather than a single rated figure, 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. 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.

| 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). |
| 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. |

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.

Feeding filtered, regulated air to pneumatic clamps that hold workpieces during machining or assembly, where the fixture is designed around a modest regulated pressure and the operator bleeds the bowl drain at shift checks.
Conditioning the air supply to carton-sealing and case-packing cylinders on a packaging line, keeping water and debris out of the valves while holding the low regulated pressure the machine builder specifies.
Supplying regulated air to gate, stopper and diverter cylinders along a conveyor system, with the bar-reading square gauge letting line staff verify the setpoint at a glance during walk-rounds.
Start with the size and port step: GFR600 is the largest GFR frame, and its 3/4 in NPT port should match your line size and the flow your circuit needs. Because this unit is the low-pressure regulator type, it suits circuits regulated to modest pressures; the exact adjustment range for the low-pressure type is not published in the catalogue, so ask us to confirm it against your setpoint before ordering. The manual drain here means an operator opens the drain periodically - choose the automatic or differential-pressure drain variant instead if the unit will be hard to reach. The 40 um element is the standard grade; specify the W variant if the downstream equipment needs 5 um filtration.
Other decodable choices: the embedded square gauge on this unit reads in bar (MPa, psi and an external round gauge are alternatives), the T suffix gives NPT threads where PT is the standard and G is the other order option, and a reverse/check valve is available as a variant. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back 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. Send us your line pressure, set pressure and expected air demand, and we will confirm the flow and the full datasheet for this model on request.
The M in the code specifies a manual drain: an operator opens the drain periodically to expel collected water. AirTAC also offers an automatic drain (code A) and a differential-pressure drain (blank) on GFR units, which suit installations where the bowl is not easily reached.
