The AirTAC GFR60020LF3WT AirTAC Filter Regulator 3/4 in NPT is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60020LF3WT is a size 600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This configuration carries a 3/4 in NPT port, a 5 um filter element (the finer option against the 40 um standard), a differential-pressure drain and the low-pressure regulator type, so it is aimed at circuits that run at reduced settings rather than full line pressure. The aluminium alloy bowl, embedded square gauge scaled in bar and the included mounting bracket are all part of this code.
This is a genuine AirTAC part from the GFR series, which spans sizes 200 to 600 with ports from 1/8 to 1 in and PT, G or NPT thread options. Filter grade, drain type, gauge style and scale can all be selected to match the installation. Flow for the series is published as curves rather than a single rated figure, so ask us to confirm sizing and the full datasheet 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". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 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. |
| W | Filtering grade 5 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.

Feeding spray guns and atomising heads on a paint line, where the air must be cleaned of water and particles and held at a reduced, stable setting by the low-pressure regulator.
Supplying clean, regulated air to the cylinders and actuators on a packaging machine, with the 5 um element helping protect valve and seal surfaces from fouling.
Holding steady reduced pressure to clamping cylinders on a machining fixture, while the differential-pressure drain carries off condensate collected in the aluminium bowl.
Size choice drives port and flow capacity: the 600 series carries the 3/4 in port of this model, with smaller 200/300/400 options in the family for lighter duties. Drain type is a real decision - differential-pressure (as fitted here), automatic or manual - depending on how often the bowl can be tended. Filter grade is 40 um standard, with this model's 5 um (code W) chosen where finer protection is needed. Gauges come as the embedded square type with MPa, psi or bar scales; this unit reads bar. Thread is PT as standard, with G and NPT as catalogue order options - this model is NPT. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature is -5 to 70 C, non-freezing. Flow for the series is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and the full datasheet figures for this model on request.
The L marks the low-pressure regulator type, intended for circuits that run at reduced settings rather than full line pressure. The exact adjustment range for this variant is not published in the standard table, so ask us to confirm it for your application. The filtration, drain and gauge functions of the unit are unchanged.
