The AirTAC GFR600-20 AirTAC Filter Regulator 3/4 in PT, 5 um 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 GFR600-20 is a size-600 filter regulator: a single body that first removes water and particulate from compressed air and then regulates downstream pressure. This configuration carries a 3/4 in PT port, the fine 5 um filter element (code W), a differential-pressure drain that bleeds condensate automatically whenever the pressure drop across the element rises, and an embedded square gauge scaled in psi. It is the low-pressure type, intended where regulated pressure sits below what a standard unit is set up for.
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, PT as standard and G or NPT threads as order options, plus drain, filter-grade, gauge and bracket choices. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.

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 clean, regulated air to carton-forming and sealing heads on a packaging line, where the 5 um element protects directional valves and the low-pressure type suits lighter clamping pressures.
Supplying filtered, low-pressure air to bench-top test rigs and analytical equipment that cannot tolerate water or fine particulate in the supply line.
Conditioning the air ahead of spray guns and atomising valves, where the 5 um grade keeps moisture and debris out of the finish and the regulator holds a steady, lower set pressure.
Size 600 with a 3/4 in PT port is the largest step in the GFR range; step down to 300/400 sizes if your line runs lighter flow, since the right match depends on the air demand of the circuit. The 5 um element (code W) suits points of use that need finer air than the standard 40 um grade. The differential-pressure drain is the default and needs no operator attention; an automatic or manual drain can be ordered instead if your duty cycle calls for it. The square gauge here is scaled in psi, with MPa or bar scales and an external round gauge available. PT is the standard thread; G (BSPP) and NPT are order options. A mounting bracket is included.
Because flow for this series is published only as curves and not as a single rated number, we cannot quote a flow figure here. 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, downstream demand and allowable pressure drop, and we will confirm the sizing from the datasheet on request.
Code L marks the low-pressure regulator type, intended for applications where the regulated pressure sits below the standard unit's normal range; the exact range for this variant is not published, so ask us to confirm it. The differential-pressure drain is the default drain on this unit: it discharges collected condensate automatically whenever the pressure drop across the 5 um element builds up, with no operator action needed.
