Will an EXAIR Vacuum Work with This Material?

Activated carbon pellets in need of vacuuming

At the heart of EXAIR’s dry vacuum systems are a modified design to our Line Vac air operated conveyors.  These units convert a compressed air supply into a powerful vacuum source with no moving parts and thus no components to wear out.  This, in turn, translates to an instantaneous vacuum supply that is both durable and maintenance free.

These aspects of our vacuum systems led a pharmaceutical research company in Macau to contact us about using a Heavy Duty Dry Vac in one of their applications.  The complete details of the application were proprietary, but information about the specific use was made available.

What this customer needed to do, was to vacuum activated carbon chips in batches of ~300kg (660 pounds) into a contained drum or bag.  The ultimate question in the application was whether an EXAIR Heavy Duty Dry Vac system can vacuum 300kg of activated carbon.  And, if it can, how long will it take?  To answer these questions we turned to a bit of data about the activated carbon, and the potential vacuuming rate of the Heavy Duty Dry Vac System.

Activated carbon has a bulk density of ~0.52 g/cm³ (~32.5 pounds/ft³), and the Heavy Duty Dry Vac can vacuum this type of material at a rate of ~30kg/min. or more (~66 pounds/min. or more).  This means that we’ll be able to vacuum the full 300kg of activated carbon in ~10 minutes!

But, where will it all go?

If we were to use a 55 gallon Heavy Duty Dry Vac, we could vacuum ~105 kg. (232 pounds) of this material before filling the drum.  But, if we use a 110 gallon system, we will double this capacity while keeping the performance and compressed air demand of the system exactly the same.

The multiple sizes of EXAIR vacuum systems provided a wide array of solution options in this application.  After discussing these options and receiving a request for distributor contact in China, we passed this customer over to our Chinese distributor.

Providing solutions for industrial applications is the forte of EXAIR Application Engineers.  It doesn’t matter if the application is here in the States, or overseas, we’re available for any questions our customers have.

If you’d like to discuss your application with an EXAIR Application Engineer we’re available by phone, email, or online chat.
