The AirTAC GFR600C20ALC3TK 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 GFR600C20ALC3TK is a size 600 filter regulator: filtration and pressure regulation combined in a single body, with a 3/4 in NPT port. It removes water and particulate from compressed air with the standard 40 um element while the low-pressure regulator sets downstream pressure, and the fitted round gauge in bar scale lets you read the setting at a glance. This configuration carries an automatic drain, so collected condensate is expelled without manual attention, and a reverse/check valve is fitted. At size 600 the bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working 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 port options from 1/8 in to 1 in, PT as standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drain, a 40 um standard or 5 um (code W) filter element, gauge style and scale choices, and bracket options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

At the 3/4 in main air drop feeding a carton-forming and wrapping line, the unit strips water and particulate from the shop air and holds a steady lowered pressure to the line's cylinders, while the automatic drain keeps condensate off the floor without daily attention.
On a conveyor system with pneumatic drives, gates and stoppers, the filter regulator supplies clean, regulated air to the valves and actuators along the line; the round bar gauge gives operators a visible setpoint check at the supply point.
For pneumatic clamps and fixtures on a CNC machining cell, the low-pressure regulator type suits circuits that work at reduced settings, the 40 um element protects the clamp valves from dirt and water, and the check valve helps hold the circuit if supply pressure dips.
Start with the port and size: this unit is size 600 with a 3/4 in NPT port, the largest step in the GFR range, suited to lines with substantial air demand. Drain type is a real choice: differential-pressure (the default), automatic as fitted here, or manual; automatic suits points where nobody wants to visit the bowl. Filter grade is 40 um standard or 5 um with code W if downstream equipment needs finer filtration. Gauge style is an embedded square gauge as standard or an external round gauge as here, with MPa, psi or bar scales. Thread is PT as standard with G (BSPP) and NPT as order options, and a bracket can be included or omitted (code J).
One honest note before ordering: flow is published as curves, not a single rated number, and this is the low-pressure regulator type whose exact adjustment range is not in the published table. Ask us to confirm sizing and the regulation range against your application 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 series as curves, not as a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Tell us your application and operating pressure and we will confirm the flow figures from the datasheet on request before you order.
The automatic drain (code A) expels collected condensate from the bowl by itself, instead of the manual drain you empty by hand or the differential-pressure drain that is the default. The L in the code marks the low-pressure regulator type, intended for circuits working at reduced pressures; its exact adjustment range is not in the published table, so ask us to confirm it on request. The unit also carries a round gauge in bar scale and a reverse/check valve (code K).
