Portable Closed Circuit Vacuum

The Hodge Vac is a portable closed circuit vacuum. It includes all the tools and fittings you need to convert any of our Hodge Clemco standard blast machine. You can convert it into a closed circuit abrasive recovery dustless blasting system within seconds. The process of closed circuit blasting uses a combined blast and vacuum head. This allows the operator to blast without the need to encapsulate the area or wear the PPE normally used for blasting.

All of our pressure blast machines can be adapted to use a closed circuit blast head. Our Aquagrit WDOS (dry), 1028NC and 1440NC blast machines are ideally suited to this due to their portability.

The key to an efficient closed circuit system is the vacuum unit used. Our Hodge Vac uses a purpose designed jet system. This is pneumatically driven and also available to ATEX standards. It also has the option to be HEPA filtered. The Hodge Vac silo has the same abrasive capacity as a 2040NC blast machine.

The Hodge Vac operates on a recover to waste principle. This makes it effective and portable. It is an ideal tool for spot repair work,  where encapsulation is expensive or ineffective. All recovered waste is discharged into a waste bag. This can be sealed and removed minimising the exposure to the operator from contaminated waste.
