The AirTAC GFR600C20ALF2T 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 AirTAC GFR600C20ALF2T is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size 600 unit is fitted with a 3/4 in NPT port, the 40 um standard filter element, and an automatic drain that bleeds collected condensate from the metal bowl (aluminium alloy at size 600) without manual attention. The regulator is the low-pressure type and carries an embedded square gauge scaled in psi, so the set pressure is visible at the unit. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of port, thread (PT standard, G and NPT as options), drain type, filter grade and gauge scale, and a mounting bracket is included with this unit. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. 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.

Feeding a stamping or assembly press that runs its air cylinders at reduced pressure: the GFR600C20ALF2T filters line water and particulate, then holds the set pressure steady while the square psi gauge gives the operator a visible setpoint.
Air preparation for conveyor-mounted sealing, labeling and case-erecting heads on a 3/4 in main: the automatic drain clears condensate between shifts without operator attention, protecting downstream actuators and valves.
Conditioning the air feeding a bank of low-pressure diaphragm or pilot-operated valves on a process skid: the 40 um element screens particulate ahead of the valves while the regulator keeps supply pressure where the valve datasheets expect it.
Step up through sizes 200, 300, 400 and 600 to match the port and the flow your line needs; this unit is the size 600, 3/4 in NPT step. Where a bowl is fitted, choose the drain: automatic (this unit, for unattended condensate removal), manual, or the differential-pressure default. Filter grade is 40 um standard, with 5 um (code W) where finer particulate protection matters. Gauge scale is selectable (MPa, psi or bar; this unit is psi), and thread is PT as standard with G and NPT order options. A mounting bracket is included.
One honest routing note: flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet before you order. The low-pressure regulator type on this unit is a real catalogue option - confirm its exact adjustment range with us on request.
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 rated flow number. Tell us your application and line pressure and we will confirm the flow curve and sizing from the datasheet on request before you order.
This configuration carries the A drain code: an automatic drain that discharges collected condensate from the metal bowl on its own. It suits unattended or hard-to-reach installations; the alternatives in the family are manual drain and the differential-pressure default, selectable by code when you order.
