In order not to brake containment at any time the HEPA filter unit is fully automated, its proper function is throughout controlled and displayed.
The HEPA filter system is equipped with a highly sophisticated control technology.
All set parameters, such as the required air volume at a set suction pressure are constantly maintained at any time and monitored at its display.
In addition, all the mechanical functions of the filter system are monitored and displayed accordingly. The necessary emptying of the dust containers are monitored and displayed by level sensors, so that the emptying of the containers takes place in time.
The respective pressure differential of each HEPA filter cassette at both filter stages is controlled and monitored so that damage of a HEPA filter cassette stage 1 is detected immediately, and thus a pollution of the environment becomes impossible. All further functions or errors are in detail monitored and transferred by potential free contacts to central controls or production machines.
Altogether the self-cleaning HEPA filter system is due to safety reasons designed in a way, so that its function is never stopped, and the production has not to be interrupted at any time.
The HEPA filter system is stopped only in the case of no energy supply. In that case an alarm is initiated in the production area, production has to be stopped and operators have to be evacuated immediately.
Monitoring the handling of the filtration system
The filter system is designed in such a way that all motors for flaps and cylinders, function automatically and thus a personnel false handling of the filter system is impossible.
