Suction with one or more suction heads
Suction directly at the point of origin
If airborne hazardous substances occur in the air that employees breathe, they must be reduced to a non-hazardous level. Effectively, sufficient protection of employees is only achieved by recording emissions close to the point of origin or release. The suction unit is directly connected to the control electronics of the machine by Computer Aided Works and can communicate with the machine.
Extraction means creating a flow of air with appropriate direction, volume and velocity that removes the hazardous materials from the breathing zone of the employees and leads them into a pipe system via an appropriate detection element. From there, the hazardous material can be disposed of safely in a variety of ways. Airborne substances are either particulate or gaseous.
After collection at the point of emission or formation, dusts must be disposed of safely. As a rule, dusts are filtered out of the air stream by a suitable separator.
Of course, the equipment requires regular maintenance. For particulate hazardous substances, the system test must be repeated annually. For purely gaseous substances, the Hazardous Substances Ordinance requires testing every three years.
