The AirTAC GFR600-20T AirTAC Filter Regulator NPT3/4 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 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 AirTAC GFR600-20T is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This unit is the size 600 frame with a 3/4 in NPT port, fitted with the fine 5 um filter element (code W), a manual drain on the bowl, a round pressure gauge reading in psi, and the standard regulator with a 0.05-0.9 MPa (7-130 psi) adjustment range. Because the drain is manual, an operator opens the drain at the bowl to expel collected condensate, which suits installations visited on a maintenance round. At size 600 the bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of 40 um standard or 5 um fine filtration, differential-pressure, automatic or manual drains, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application before you order.

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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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.

At a 3/4 in ring main drop feeding impact wrenches, clamps and air cylinders in a vehicle assembly cell, this unit filters water and particles to 5 um and holds the tool circuit at a set pressure, with the psi gauge giving the operator a direct readout.
On a bottling or carton packaging line, pneumatic diverters, pushers and stop gates run off a regulated branch; this filter regulator cleans the supply ahead of the valves and keeps the actuator pressure stable shift after shift, with manual draining done on the maintenance round.
On a test bench cycling pneumatic actuators or running air-driven fixtures, the 5 um element protects sensitive instruments and valve seats from water and fine particles, while the regulator sets a repeatable test pressure read locally in psi.
Start with the port and size step: GFR600-20T is the largest GFR frame at 3/4 in NPT, chosen when the air demand at the point of use is beyond what a 1/2 in or smaller unit should carry; match the frame against the flow curve for your consumption rather than guessing. Next, the drain: this unit is manual, so condensate is expelled by hand at the bowl - choose the automatic or differential-pressure drain variants instead if the installation is unattended. Filtration here is the 5 um fine element; the 40 um standard element is the default if only coarse water and particle removal is needed. The gauge on this unit is the external round type reading in psi; an embedded square gauge, or MPa/bar scales, are the other catalogue choices. Thread is NPT as ordered; PT is the standard thread and G is the alternative option. A mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the 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 flow number here. Tell us your line pressure and air consumption and we will confirm the sizing against the datasheet on request before you order.
The M in the code GFR60020MC2WT specifies a manual drain: condensate collected in the aluminium bowl is expelled by opening the drain by hand, which suits attended installations on a maintenance schedule. The same size 600 filter regulator is also available with an automatic drain (code A) or the differential-pressure drain (blank), which is the default.
