The AirTAC GFR60020AJC2K AirTAC Filter Regulator PT3/4, Auto Drain 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 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 GFR60020AJC2K is a size-600 GFR filter regulator: filtration and pressure regulation combined in one body, with no lubricator. It filters water and particulate from compressed air down to 40 um (the standard grade; 5 um is available as the W option) and regulates downstream pressure over 0.15-0.9 MPa (20-130 psi). This configuration is built for a 3/4 in PT port, has an automatic drain that expels collected condensate without manual attention, and carries an external round gauge scaled in psi. The aluminium alloy bowl is standard at size 600, and a reverse/check valve (code K) is fitted to hold downstream pressure when the upstream supply is lost. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing. No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR filter-regulator line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and each size can be ordered with manual, automatic or differential-pressure drain, 40 um or 5 um filtration, square or round gauges in MPa, psi or bar scales, a low-pressure regulator type, and a reverse/check valve. Flow is published in the AirTAC catalogue as curves rather than a single rated figure, so ask us to confirm the datasheet and flow 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. 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 spray-gun air drops in a paint booth: the 40 um element strips water and pipe scale that would otherwise fisheye a finish, the regulator holds a steady set pressure at the guns, and the automatic drain keeps the aluminium bowl emptied between shifts.
Conditioning the shop-air feed to a CNC machining center's pneumatic tool changer and clamps: the filter-regulator cleans and steadies the supply at the machine, the check valve holds downstream pressure through brief upstream dips, and the psi gauge lets a technician read the setpoint directly.
Supplying the air cylinders and diverters on a packaging conveyor line: the unit removes condensate and particulate before the valves, regulates branch pressure to the actuators' setpoint, and the automatic drain suits a line that runs unattended across long production runs.
Start with the port and size step: this unit is size 600 with a 3/4 in PT port, the largest step in the range, so size up from smaller GFR units when your line runs higher air demand - and have us confirm the flow curve against your consumption, since AirTAC publishes flow as curves rather than one rated number. Choose the drain to match how the unit is attended: automatic drain (this code, A) suits installations that are not checked daily; manual drain (M) suits attended points; differential-pressure drain (blank) is the default. Filtration is 40 um standard here; specify the W code for 5 um where finer particulate removal matters. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range; a low-pressure type (L) is available in the family. This code carries an external round gauge scaled in psi (scales in MPa or bar are orderable), a fitted reverse/check valve (K), and no bracket (J). Thread is PT as standard; G (BSPP) and NPT are catalogue options to order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves in the catalogue, not as a single rated number, so we will not quote a figure that is not in the datasheet. Tell us your line pressure, set pressure and air consumption, and we will confirm the flow curve and sizing for this 3/4 in unit against your application before you order.
The A in GFR60020AJC2K means the bowl drains collected condensate automatically, which suits points that are not checked every day. Manual drain (code M) is the choice where an operator is on hand to open the drain, and differential-pressure drain (no code) is the catalogue default. All three drain types share the same 0.15-0.9 MPa (20-130 psi) regulation range on this standard-type regulator.
