NilfiskCFM 3557/100 Three Phase Industrial Vacuum Cleaner
Now Replaced By The NilfiskCFM T40 InfiniClean
A powerful 4 Kw three phase industrial vacuum cleaner, gives a lesser vacuum than the 3308 but a higher airflow via a huge 35,000 cm filter area making it ideal for concrete floor grinding and concrete floor polishing and other fine dusts.
This model is ideal for use in a constant production system, which would be too demanding of traditional single phase motors with carbon brushes & armatures that wear.
The Absolute filter, upstream safety filter, a manual filter-shaker, an accessories compartment and easy access to the motor compartment, were features of these models.
