The AirTAC GFR600C20F2GK AirTAC Filter Regulator G3/4, 40 um, psi gauge 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 GFR600C20F2GK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has G3/4 ports, a 40 um standard filter element and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough, so no manual draining routine is needed. The set downstream pressure is read on the fitted square pressure gauge scaled in psi, and a reverse/check valve is fitted so downstream pressure is held if the upstream supply is lost. Maximum inlet pressure is 1.0 MPa (145 psi), the regulation range with the differential-pressure drain is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The bowl on this size-600 unit is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, a choice of differential-pressure, automatic or manual drain, a 40 um standard or 5 um (code W) fine filter element, gauge and scale options, and PT, G or NPT thread variants. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the flow and 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.

Feeding filtered, regulated air to the tool-clamp and pallet-change circuits of a CNC machining centre, where the 40 um element keeps swarf-laden shop air out of the clamping valves and the regulator holds a steady clamp pressure.
Supplying the pneumatic diverters, stoppers and pushers along a packaging conveyor line, with the differential-pressure drain handling condensate from a long main run without a daily walk-round to drain bowls by hand.
Conditioning the air drop that feeds the air tools, grippers and cylinders in a factory assembly cell, with the reverse/check valve holding the set pressure downstream if the shop-air supply is interrupted mid-cycle.
Step up or down through the GFR sizes (200/300/400/600) and their port sizes (1/8 in to 1 in) to match the air consumption of the circuit being fed - the 600 size with its G3/4 ports sits at the high-capacity end of the range. Choose the drain to suit access: differential-pressure (this model) drains itself with flow, automatic drains on a level or timer basis, and manual suits positions someone visits anyway. Pick the 40 um standard element for general plant air, or the 5 um (W) element where finer particulate removal matters; select the gauge scale (MPa, psi or bar) and the thread standard - PT is the standard, with G and NPT available as order options. A bracket is included with this unit.
One honest note before you order: AirTAC publishes flow for this series as curves, not as a single rated number, so we do not quote a rated flow figure here. Send us your application details and we will confirm the sizing and datasheet figures against the curve before you commit.
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 rather than as a single rated figure, so we do not state a rated flow number here. Tell us your application and we will confirm the flow from the datasheet curve on request before you order.
The differential-pressure drain (the default on this model) discharges collected condensate automatically when the pressure drop across the 40 um element rises, so it suits installations that are not visited daily. If you prefer a drain that reacts to condensate level, choose the automatic (A) version; if someone is at the unit regularly anyway, the manual (M) version is the simplest choice. Note that with the differential-pressure drain the regulation range is 0.15-0.9 MPa (20-130 psi).
