The AirTAC GFR60020ALF2T 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 automatic 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 GFR60020ALF2T is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This configuration is built with 3/4 in NPT ports, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, the low-pressure regulator type, and an embedded square gauge reading in psi. The bowl is aluminium alloy, as fitted on the 600 size, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, plus drain, filter-grade, gauge, thread and bracket choices. Because AirTAC publishes flow as curves rather than a single rated figure, we confirm flow and other datasheet values 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. 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". |
| A | Drain: Automatic 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. |
| 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. |
| 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.

Filtered, low-pressure regulated air feeding pneumatic swing clamps and part pushers in a stamping cell, with the automatic drain clearing condensate from humid shop air.
Clean, pressure-stabilised air for gating and diverting cylinders on a carton packaging conveyor, where a steady low set pressure keeps indexing repeatable.
Local air preparation for a pilot-plant skid running low-pressure pneumatic valves and actuators, with water and particulate removed ahead of downstream instrumentation.
Size and port are the first choice: step through 200, 300, 400 and 600 as flow demand and pipe size grow; this unit sits at the 600 size on 3/4 in NPT ports. Drain comes as differential-pressure (default), automatic (this unit) or manual. The filter element is 40 um standard or 5 um with code W. The embedded square gauge is standard (psi on this unit; MPa or bar scales available) and an external round gauge is optional. Thread: PT is the standard, with G (BSPP) and NPT as order options - this unit is NPT. A mounting bracket is included. Flow 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 GFR600 as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and air demand and we will confirm the flow from the datasheet for your application before you order.
The automatic drain (code A) expels collected condensate on its own, which suits unattended or humid installations. The GFR600 is also available with a manual drain (M) or the differential-pressure drain (default). This unit is the low-pressure regulator type, so confirm the adjustment range for your set point with us on request.
