Dust and fumes extractor with automatic filter cleaning system
The Airflow EV PN is the most powerful unit of the Airflow range, thanks to a 4kw motor. It is equipped with an automatic pneumatic cleaning of the filter cartridge. Thanks to these characteristics it can be used for both localized extraction and filtration or as suction unit on centralized air filtration systems.

The automatic cleaning system with reverse air pulse, also called PN system, is the most effective way to keep cartridges free from dust particles which may reduce the suction performance. The system consists of a tank for compressed air, placed behind the filter chamber. This is filled by a compressor that can possibly be provided with the vacuum cleaner. Every 30 seconds (more or less depending on the application), the system shoots a jet of air at 6 BAR within a cartridge at a time. The air pressure inside the cartridge, having a force much higher than the vacuumed air outside, detaches the dust particles from the surface of the filter, cleaning it. In this way you can clean all cartridges, effectively, and without stopping the vacuum.

Thanks to this filters’ cleaning system, to the excellent vacuum performance and Delfin’s know-how in the design and construction of centralized filtration systems, the Airflow EV PN vacuum cleaner is the ideal machine for the application as a central vacuum cleaner on implants.
