  • For solids and liquids
  • Lower maintenance costs
  • Self-cleaning cyclone separation

The KOKS CycloVac air displacement system with cyclone separator is designed for heavy industrial applications and is suitable for suctioning, displacing (option), transporting and discharging dry, wet and hazardous substances, such as various types of catalyst, (roof) gravel, powders, fly ash and sludge. Specially developed for working with hazardous and contaminated substances, the system is available in ASME, DOT 407/412 and/or ATEX (Ex) (pump system) versions and built in accordance with all applicable safety standards.


The KOKS CycloVac is the perfect air displacement system for heavy duty suction, displacement and transportation activities in the construction and (petro)chemical industries and for all general industrial applications.


The powerful Roots blower gives the KOKS CycloVac air displacement system a very high suction and displacement capacity, which
makes it possible to process and transport large quantities of dry substances, liquids, gravel, sand, etc. in a very short time. The user benefits
from significant time savings and a huge reduction in cost.


The KOKS CycloVac air displacement system can be fitted with various option kits that are appropriate for your needs, for industrial
applications and/or for sewer cleaning activities.

Safety information


  • Easy control.

  • Suction with 4767 CFM, max. 28 inHg underpressure; blowing with 15 psi overpressure.

  • 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, DOT 407/412.

  • 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.

Designed and certified for:

  • assembly on a 3-axle, min 400 HP chassis.
  • suctioning, displacing (option), transporting and discharging dry, wet and hazardous substances, such as sludge, sand (roof) gravel, fly ash, powders and various types of liquids.
  • ASME approved.
