The AirTAC GFR600C20LC3TK AirTAC Filter Regulator NPT3/4 Low-Pressure 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 GFR600C20LC3TK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/4 in NPT port, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises, and a low-pressure regulator type for circuits set below standard regulator ranges. It is fitted with an external round gauge scaled in bar, a reverse/check valve that holds downstream pressure when the upstream supply is lost, and a mounting bracket. The size 600 bowl is aluminium alloy. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, thread options PT (standard), G and NPT, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um (W) filtration, gauge style and scale options, and an optional reverse/check valve. Flow for this series is published as curves rather than a single rated figure, so we 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.

Feeds the clamp and pusher cylinders on an end-of-line palletizer, filtering condensed water from the main drop and holding a steady low set pressure so gripper sequencing stays repeatable through the shift.
Conditions the shop-air feed to a machining centre's tool-change and clamping circuit: the 40 um element stops scale and pipe debris reaching the directional valves, and the check valve holds clamp pressure if the main supply drops.
Mounted at the take-off for a packaging line's diverters and stopper gates, draining accumulated condensate automatically and regulating a reduced supply pressure for the light-duty actuators downstream.
Size up through the GFR range (200/300/400/600) by the port and flow your line needs - this unit is the largest step, at 3/4 in NPT. Where this code is already fixed, the remaining decodable choices are: drain type (differential-pressure as fitted here, automatic, or manual for a fully controlled blow-down), filter grade (40 um standard element, or 5 um with code W where finer particulate removal is needed), gauge style and scale (this unit carries an external round gauge in bar; an embedded square gauge with MPa/psi/bar scales is the standard alternative), thread (PT is the catalogue standard; G and NPT are order options - this unit is NPT), and bracket (included here; code J deletes it). The low-pressure (L) regulator type is the right pick when the circuit runs at set pressures below the standard type's range; the exact adjustment range for the low-pressure type is not published, so ask us to confirm it against your setpoint. Flow is published as curves, not a single rating - send us your flow and pressure requirement and we will confirm sizing from 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 series as characteristic curves rather than a single rated figure, so we do not quote one number here. Tell us your upstream pressure, set pressure and required flow, and we will confirm the sizing from the datasheet curves on request before you order.
The C3 in the code specifies an external round gauge scaled in bar. An embedded square gauge is the standard fitting, with MPa, psi or bar scale options, so a different gauge style or scale can be ordered by changing that code position. The thread is NPT on this unit; PT is the catalogue standard and G is also available as an order option.
