The AirTAC GFR600C20F2K AirTAC Filter Regulator PT3/4, 40 um 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 GFR600C20F2K is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 600 unit has PT3/4 ports, 40 um standard filtration and a differential-pressure drain that bleeds condensate automatically whenever the pressure differential across the element is high enough, so no manual draining routine is needed. The set pressure is read on the fitted embedded square gauge scaled in psi, and the built-in reverse/check valve holds the downstream setting if upstream supply is interrupted. The aluminium alloy bowl suits higher-temperature or impact-exposed installations, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with a choice of drain type, 40 um or 5 um (W) filtration, gauge scale in MPa, psi or bar, and G (BSPP) or NPT thread options in place of the PT standard. Flow figures for this family are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures 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.

Cleaning and regulating the 3/4 in supply branch that feeds the carton-sealing and case-erector cylinders on a packaging line, with the check valve holding the set pressure during brief upstream drops.
Conditioning the air feeding stopper, gate and pusher cylinders along a bottling or food conveyor, where the differential-pressure drain keeps condensate off the actuators without daily bowl draining.
Filtering and regulating the air supply to a machining centre's clamp and tool-change circuit, with the psi-scaled square gauge giving operators a direct set-point readout at the machine.
Start with the port step: size 600 with 3/4 in PT ports is the largest GFR frame, so match it to the branch of your air system whose flow demand sits at the top of the range; smaller 200/300/400 sizes cover lighter lines. Choose the drain to suit access: differential-pressure (this model) drains itself, automatic (A) drains on a cycle, and manual (M) needs someone to open the bowl. Filtration is 40 um as fitted here, or 5 um with code W where downstream valves and instruments need finer protection. The gauge can be ordered with MPa, psi or bar scale, and the thread can be G (BSPP) or NPT instead of the PT standard; a bracket is included for panel or wall fixing. Flow for this family is published as curves, not a single rating, so 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. 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 family as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and required flow and we will confirm the datasheet curve figures for this size 600, 3/4 in unit on request.
The differential-pressure drain on this model releases collected condensate automatically when the pressure drop across the filter element rises, so it suits installations that are not checked daily. If you prefer a fixed drain cycle, order the automatic (A) version; if the unit sits where someone can open the bowl routinely, the manual (M) version is the simplest choice. Note the regulation range differs by drain type: 0.15-0.9 MPa (20-130 psi) for automatic and differential-pressure drains, 0.05-0.9 MPa (7-130 psi) for manual.
