The AirTAC GFR600C20C1TK AirTAC Filter Regulator NPT3/4 with 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 GFR600C20C1TK is an AirTAC GFR600 filter regulator: a single body that removes water and particulate from compressed air and then regulates downstream pressure. This size 600 unit is fitted with a 3/4 in NPT port, the standard 40 um filter element, 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 regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the C1 suffix means an external round gauge scaled in MPa is fitted so the set pressure is always visible. A reverse/check valve (K) is also fitted, and a mounting bracket is included. Because this is the 600 size, the bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature range of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of PT, G or NPT thread, manual, automatic or differential-pressure drains, a 5 um element option, gauge scale choices, and an optional reverse/check valve. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for your application before you order.

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 pneumatic clamps, tool-change cylinders and control valves on a machining centre, with the round MPa gauge letting setters verify set pressure at the drop.
Conditioning the air feeding pick-and-place cylinders and diverters on a carton packaging line, where the 40 um element protects directional valves and the regulator holds a steady actuator pressure.
Supplying clean, regulated air to pneumatic control valves and positioners on a bottling or process line, with the reverse/check valve holding the set pressure if the upstream supply dips.
Step up or down through the GFR sizes (200, 300, 400, 600) to match the port and the flow your line needs; this unit sits at the top of the range with a 3/4 in NPT port. Choose the drain to suit maintenance practice: differential-pressure (this unit) drains itself on load, automatic drains on a cycle, and manual drain suits infrequently attended installations. The 40 um element fitted here is the standard grade; specify the W suffix for the 5 um grade where finer filtration is required. Gauge scale can be MPa, psi or bar, and the thread can be ordered as PT (standard), G or NPT - this unit is NPT. A bracket is included, and the K suffix adds a reverse/check valve.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the datasheet and check the sizing against your required flow 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 flow number. Ask us and we will confirm the datasheet and check the size 600 unit with its 3/4 in port against the flow your application needs before you order.
C1 means an external round gauge scaled in MPa is fitted (the embedded square gauge is the standard fitting, and psi or bar scales can be ordered). T means the thread is NPT - PT is the standard thread and G is the other catalogue option. K means a reverse/check valve is fitted, which holds downstream pressure against a temporary upstream loss.
