Fully automatic safety
One of the intelligent solutions of SEKA protective ventilation systems is an automatically controlled blower. At the time of delivery, effective sealing requires only 30% of the maximum blower rotation in order to achieve an air pressure of 130 Pa inside the cabin. This value will be increased automatically in order to compensate for the increasing filter resistance and keep the overpressure inside the cabin at a constant level.
Our high-performance blowers in combination with filters positioned at the pressure side of the system are able to generate differential pressures of several hundreds of Pascal. This puts the SEKA technology in a position to maintain a constantly pressurized cabin while guaranteeing maximum filter life.
Comfort with cost benefits
The pressure-dependant blower control not only automatically adjusts itself to the changing filter resistance. It also compensates leaks in the outer skin of the cabin. This will ensure continuously reliable operation of the protective ventilation system without any manual interference.
Another aspect is a solid economic advantage due to high filter life and increased availability of the machine, since the safety of operators es guaranteed even if the cabin is not completely tight.
