Primus F620 – Versatile Air Leak Detector

The next generation of measurement.

The ATEQ® Primus F620 is the state of the art color screen compact air leak detector designed to test the air-tightness of parts on production lines. It is specially adapted for automatic and semi-automatic workbenches. The method used is based on the measurement of a small variation or drop in differential pressure between the test and reference parts, when both are filled to an identical pressure.  This versatile instrument can be used for indirect tests, sealed component testing and high speed testing of components with small volumes with the optional “mini-valve”.

  • User friendly “Plug & Play” interface
  • Mini-Valve, Indirect and Sealed Component Test Options
  • Fully backwards compatible, just plug into existing PLCs and test benches without reprogramming
  • Small & Compact
  • Gigantic memory to store all trial parameters & tests

ATEQ “Mini-Valve”

The ATEQ® “Mini-Valve” is an optional high-speed valve optimal for quickly testing components with small volumes.

In the pressure decay world, volume is the big enemy. The more volume is filled, the longer it takes to get into the test pressure, to stabilize and to test the part.

For small parts (up to 5cc) the absurd situation is that most of the volume tested is in the pipes and internal pneumatics of the instrument.

A standard ATEQ® valve is already twice as small as the nearest competitor. But ATEQ® has gone further with its mini-valve that has allowed it to achieve total cycle time (fill, stabilize, test, dump) down to 0.2 sec for leak rates as low as 0.5 cc/min.

Temperature Compensation

This is the crown jewel technology of ATEQ®. Not only does it compensate for temperature variations, but it learns from the results it gets and adapts itself to those results in a smart way.

Ballistic Full Feature & Electronic Regulator

Again, this feature is an ATEQ® exclusivity. In some applications, filling the part takes more than 1/3 of the total cycle time. ATEQ® has this innovative feature that will let the electronic pressure regulator open fully for a small amount of time, so the part fills up faster. The “Ballistic fill” does not only fill faster. It also helps to stabilize the part’s volume faster.

High Pressure

ATEQ® Primus can leak test components up to 80 bars (1250 PSI) in differential pressure mode. That remains unmatched in the industry.

Sealed Part Testing

Is your component sealed?

The Primus F620’s “Sealed component” can test components that do not have any openings to test.

What is so special about sealed components?

With pressure decay leak testers, the problem isn’t so much to find a small leak in a sealed part, but rather to detect a gross one. If the component has a big leak, then the internals will get filled at the fill stage, leaving no pressure to drop once the instruments gets into the test stage. ATEQ® has invented and patented the sealed component technic by performing a volume test prior to leak testing your part. So if there is a gross leak, the volume will be higher than expected and the test will fail.

The range of ATEQ® Leak Testers can be fit with as many as 6 different technologies. Most Leak Testing companies around the world claim that this or that technology is better than the others … and they are all right. Each technology is best suited for specific applications but ATEQ® is the only company that masters them all.

Furthermore, ATEQ® has improved each of these technologies thanks to its 50+ development engineers team who work all year long with end users to solve real life application issues.


Differential pressure decayThe most popular

By far the most popular technology, differential pressure decay uses a reference volume to test your part. This helps compensate for any ambient pressure or temperature variations as they occur on both parts simultaneously.
Only a leak on the test part will result in a movement of our transducer’s membrane.

The second advantage of this method is that the accuracy does not drop with the test pressure as the transducer is measuring pressure differences between the two circuits, as opposed to the traditional pressure decay technology that measures pressure drops against the atmosphere.

Leak ranges (in Pascal/second):

From 1 to 5000 Pa/sec pressure drops (Values in cm3.atm/min depend on the test volume)

Maximum resolution:

0.1 Pascal
