The AirTAC GFR600C20AC3T AirTAC Filter Regulator 3/4 in NPT 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 See datasheet 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 GFR600C20AC3T is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This configuration is the 600 size with a 3/4 in NPT port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filtration element, and a round pressure gauge with bar scale fitted. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with matching port sizes, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing figures 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 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.

Clean, regulated air ahead of the machine tool's pneumatic manifold: the 40 um element strips water and swarf-laden condensate while the regulator holds a steady setpoint for clamps, tool changers and chip conveyors.
Feeding cylinders and diverters on a packaging or palletising line, where the automatic drain keeps the bowl clear between shifts and the 3/4 in port serves a main drop feeding multiple stations.
Point-of-use prep before spray guns and air-assisted applicators: filtered, pressure-stable air helps finish quality, and the bar-scale gauge gives operators a clear setpoint reference at the booth.
Work size and port against the air demand of the machine: 200, 300, 400 and 600 step up in port and capacity, and this unit is the 600 size on a 3/4 in NPT connection. Choose the drain to suit access: automatic (this unit) suits points that are hard to reach or left unattended, manual suits attended stations, and differential-pressure drain is the catalogue default. Filter grade is 40 um standard; specify 5 um (code W) where finer protection is needed. Gauges come as an embedded square gauge or an external round gauge, with MPa, psi or bar scales (this unit: round, bar). Thread is PT as standard, with G and NPT as order options, and 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 GFR series as curves, not as a single rated figure, so there is no one number we can quote. Send us your air demand and line pressure and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code selects the automatic drain: collected condensate is expelled without anyone opening the drain by hand. That suits drops that run unattended or sit in awkward spots. Manual drain and the differential-pressure default are available on other GFR600 configurations if you prefer.
