The AirTAC GFR60020AF2GK AirTAC Filter Regulator 3/4" G Port 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 GFR600 series combines water and particulate filtration with pressure regulation in a single body, so one 3/4-inch unit both cleans the compressed air and holds your downstream pressure steady. This configuration is the size-600 G-thread (BSPP) version with an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, a built-in square gauge reading in psi, a reverse/check valve to hold settings if supply pressure is lost, and a mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 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 family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options include a 5 um element (code W), manual or differential-pressure drain, alternative gauge scales (MPa, psi, bar), NPT or PT threads, and low-pressure regulator types. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Clean, regulated air at the cell inlet keeps clamps, tool-changers and pneumatic actuators on a machining centre working consistently; the 3/4-inch port suits the main drop feeding the cell, and the psi gauge lets setters verify set pressure at a glance.
On a filling or cartoning line, the filter stage removes water and pipe scale before air reaches cylinders and grippers, while the regulator holds a stable setting for repeatable motion; the automatic drain handles condensate on a line that runs unattended across shifts.
At a 3/4-inch branch off the factory ring main, this unit gives each assembly bay its own filtered, regulated supply; the reverse/check valve holds the downstream setting during supply dips, and the aluminium bowl suits a heavier-duty main-line position.
Start with the size and port: 600 is the largest G-series frame, and this unit carries a 3/4-inch G (BSPP) port - step down to 400/300/200 if your line is smaller, or stay at 600 for higher-demand mains. Drain choice matters: automatic (this unit) suits unattended or hard-to-reach installations, manual suits periodic checks, and differential-pressure drain is the default. The 40 um element is standard; specify the W code for 5 um where finer particulate removal is needed. The square psi gauge is fitted here; MPa or bar scales and an external round gauge are alternatives. Thread is G (BSPP) on this unit - PT is the standard offering and NPT is orderable - and a bracket is included. Because flow is published as curves rather than a single rating, send us your flow and pressure requirements 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. 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 rather than a single rated figure, so we do not quote one number here. Tell us your line pressure, set pressure and required air consumption, and we will confirm the flow from the datasheet and check the sizing against your application before you order.
The A in the code sets the automatic drain: collected condensate is expelled without anyone opening the bowl, which suits installations that run unattended or sit in awkward positions - manual and differential-pressure drain versions are available if you prefer. The K at the end of the code means a reverse/check valve is fitted, holding the regulated downstream pressure if the upstream supply is lost. This unit also carries a 40 um element, a square psi gauge, a G (BSPP) 3/4-inch port and an included bracket.
