DG HD Series

Powerful side channel blower, built-in automatic cleaning system and extremely high suction pressure; these are just some of the reasons why the DG 300 HD industrial vacuum system is not just a simple industrial vacuum, but a veritable tool for handling or removing large amounts of material. This vacuum can increase the efficiency and productivity of any heavy industry, from cement factories to foundries. Wherever there are large and heavy amounts of materials. Best when used in a centralized vacuum system in combination with Delfin’s filtering and separating units. For more innovations associated with this model, see “related products” section below.
