  • Self-cleaning cyclone separation keeps the cyclones dust free at all times (patented).

  • Cyclone separation instead of filter separation on behalf of: - lower maintenance costs. - less resistance (no trouble by filter pollution). - more user-friendly suctioning of liquids.

  • Approved in accordance with ASME American type-approval - PED or ADR (CEOC) European type-approval.

  • Built to the latest environmental and safety standards.

  • Optimum balance between a chassis with a short wheelbase and maximum tank capacity.

  • Available as skid.

  • Ergonomic and chassis-dependent construction by means of a versatile auxiliary frame and an adjustable pump angle.

  • Blower is mounted in the middle of the chassis for a better load distribution.

  • Light construction provides a good load distribution and offers the possibility to be assembled on a 3-axle chassis with a large loading capacity.

  • High-quality, long life span and economically justified purchase price.

  • By easy cleaning and exchanging the safety filters, the machine is versatile and various products can be vacuumed up one after the other, without causing pollution.
