The AirTAC GFR60020MLC1T 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 GFR60020MLC1T is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single 600-size body with a 3/4 in NPT port. This configuration carries a manual drain, the standard 40 um filter element, the low-pressure regulator type, and a round pressure gauge with an MPa scale. The size-600 bowl is aluminium alloy, and a mounting bracket is included.
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, and is available with manual, automatic or differential-pressure drains, a 5 um element option, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details for your application before ordering.

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. |
| (blank) | No reverse-flow valve (the default). |
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.

Point-of-use air preparation on a plant-wide 3/4 in distribution header, cleaning and holding supply pressure for downstream pneumatic tool circuits.
Conditioning the air feed to conveyor-mounted pneumatic actuators and clamps, where a set pressure must be held steady through each indexing cycle.
Supplying filtered, regulated air to pneumatic valve manifolds and positioner circuits where a low set pressure is required and a manual drain suits a supervised installation.
Step up or down through the GFR sizes (200/300/400/600) against the port and flow your line needs; this unit is the 600 size on a 3/4 in NPT thread. Choose the drain to suit maintenance practice: manual (as here, which also widens the standard regulation span), automatic, or differential-pressure. The 40 um element is standard; specify the W code for 5 um where finer filtration matters. Gauges come as an embedded square gauge or an external round gauge, with MPa, psi or bar scales - this unit has the round MPa gauge. Threads are PT as standard with G and NPT as order options, and a bracket is included.
Because flow is published as curves rather than 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. 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 figure, so we do not quote a number here. Send us your line pressure, set pressure and expected air demand, and we will confirm the sizing against the datasheet on request.
The M in the code selects a manual drain: collected condensate is released by hand rather than automatically. On filter regulators the manual-drain version also carries the wider standard regulation span, while automatic and differential-pressure drains suit unattended installations. This unit also uses the standard 40 um element; the W code gives a 5 um element if finer filtration is needed.
