The low-cost Pack-Vac leak detection system can now be supplied with a special attachment to test vacuum packs for leaks.

Pack-Vac uses only water and compressed air to detect any leaks and is already an ideal alternative to the bell-jar or conventional water tank method of testing nonvacuum packs and MAP.

With this new attachment the Pack-Vac can be used to test for leaks in vacuum packs found in many industries including food packaging, pharmaceutical packaging and cosmetic packaging as well as other industrial packaging.

The unit is very portable and is available with six different size chambers ranging from 203 x 280 x 203 to 508 x 813 x 660mm.

It is extremely easy to use - the package is placed in the chamber filled with water and compressed air is applied at between 5 and 8bar.

The immersed package inflates and any leak is indicated by a stream of bubbles The benefits of using Pack-Vac include test times of around 30 seconds, no calibration of the equipment is required, no special skills are required to use the equipment, it is simple to maintain and has an easy to clean Perspex housing, no electrical connections are required nor is there a need for a vacuum pump.

Carl Long, General Manager at Witt Gas commented: "Because Pack-Vac can now test vacuum packs, it has opened up a new market sector for Pack-Vac and because it is much simpler and easier to use than other systems for detecting leaks in vacuum packs, operators require very little training".
