Flex Rent

Flex Rent is the distributor of KOKS vacuum trucks for the USA and we own and operate a rental fleet of KOKS vacuum trucks based out of the Houston Texas area. Our fleet consists of the KOKS Ecovac: a pressure/vacuum truck and the KOKS Cyclovac Pro: truck with an air displacement system with a patented automatic self cleaning cyclone system.

KOKS Cyclovac Pro

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 blower gives 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.


This pressure and vacuum truck is perfect for day-to-day suction, discharge and transportation activities, general industrial cleaning or for use in the (petro)chemical industry and in refineries. The powerful liquid ring vacuum pump allows large quantities of (fluid) substances to be processed in a short time. The user benefits from significant time savings and a huge reduction in cost.
