The AirTAC AirTAC GFR600-20 Filter Regulator 3/4in NPT 5um 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 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 AirTAC GFR600-20 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit is built with a 3/4 in NPT port, a 5 um filter element for finer filtration than the standard 40 um grade, and an automatic drain that expels collected condensate without manual attention. The regulator is the low-pressure type, and an embedded square gauge with a bar scale is fitted so the set pressure is visible at the unit. The bowl on this size is aluminium alloy, and no mounting bracket is included with this configuration.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with a choice of ports, drain types, filter grades, gauge styles and scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 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. |
| J | Supplied without bracket. |
| (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 filtered, pressure-controlled air to a pneumatic press or clamping fixture on a fabrication line, where the 5 um element protects valves and cylinders and the low-pressure regulator holds the working setting.
Conditioning air for conveyor diverters, baggers and carton-sealing cylinders on a packaging line, with the automatic drain clearing condensate on equipment that runs unattended through shifts.
Installed at a 3/4 in air drop serving a production cell, filtering water and particles from the header supply and regulating pressure before it reaches the cell's distribution manifold.
Start with the port: this unit is 3/4 in NPT, and the size 600 step is the right choice when the line's required flow sits above what smaller 200-400 bodies serve. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering. Next, the drain: automatic drain suits points where the unit is not checked daily; manual and differential-pressure drains are available on other configurations. The 5 um element (code W) is the finer choice over the standard 40 um grade when downstream equipment needs cleaner air. The fitted square gauge reads in bar; MPa and psi scales and an external round gauge are options. PT is the standard thread and G or NPT are catalogue options to order; brackets are optional and not fitted here.
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 this series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line's flow demand and we will confirm the datasheet curve figures for the GFR600 size on request before you order.
This configuration carries code A, an automatic drain that discharges collected condensate from the aluminium bowl on its own. It suits installations that are not checked daily; manual and differential-pressure drain versions are available if you prefer a different arrangement.
