Basic belt conveyors can basically only carry horizontal or gently sloping, but the EcoCuum can accommodate various layouts such as vertical, turn, and steep by adsorbing lightweight conveyed objects. EcoCuum sucks air through a gap in the plastic module chain with a fan and creates negative pressure to transport the goods while adsorbing them.

When a vacuum system is used to handle these materials, air continuously leaks into the system due to the material's porous nature. This means the vacuum pump must have the capacity of a constant pressure to maintain the desired vacuum level and hold the objects. This requires a vacuum system with a high flow rate.
