All outlets must have some type of closure, either a valve or shutter. These can be manually actuated, such as flap valves or manual shutter valves, or automatically controlled for actuation only when extraction is required. Swing arms, hose reels and other suspension arrangements help further to increase the flexibility and efficiency of the system.
An extraction system is sized for only those outlets which are to be used simultaneously. This is in order to maximize efficiency and minimize the size of the central unit. All outlets must have some type of closure, either a valve or shutter. These can be manually actuated, such as flap valves or manual shutter valves, or automatically controlled for actuation only when extraction is required.
The Flexpipe can be used for fume extraction, high flexibility and small diameter allow it to be placed very close to the fume source.
Overhead suspension arrangements such as swing-arms and hose reels can increase the usefulness of the system, increase ergonomics and minimize potential trip hazards from hose left on the floor.
When large volumes of material are to be introduced into the system, stainless floor funnels can be used from which the material is then extracted.
