Filters and filter cleaning systems
The filter is the lung of the vacuum cleaner, and traps all the impurities avoiding them to be blown back into the environment, in order to protect the health of the operators. Nilfisk uses the highest quality filters on its vacuum cleaners.
A clean filter allows your vacuum to keep the highest performance, so the filter cleaning system is a key point. Nilfisk offers different types of systems, from the manual to the most automatic.
Primary filters
The primary filters are mounted on all vacuum cleaners and trap all forms of common dust, even the finest particles; There are different types of primary filters:
- Bag filters
- Star filters
- Cartridges (used as primary filters allow the industrial vacuum to run continuously without stopping for the filter cleaning)
These filters can be in L and M class for the collection of hazardous dust and they can be in different media for the different applications such as for example in PTFE (thanks to the PTFE membrane, dust falls down easier during the filter cleaning and doesn't penetrate the filter material) or Nomex® (to be used in case of hot material).
Absolute filters
When potential hazardous dust has to be collected further absolute H class filters are needed, Nilfisk provides both upstream (located before the blower) and downstream (as last filtration stage) absolute filters. In terms of filtration efficiency the filters can be HEPA 14 and ULPA 15.
Activated carbons filters
Activated carbon filters are mainly used for the following applications:
- when malodorous materials must be removed.
- when a low concentration of pollutants must be removed as in laboratories, electronics, pharmaceutical industries.
Filter cleaning systems
A clean filter allows your vacuum to keep the highest performance, so the filter cleaning system is a key point. Nilfisk offers different types of systems, from the manual to the most automatic.
- FILTERSHAKER: manual or electric, it is easy to use and effective. Ideal for vacuum cleaners working periodically, as it needs the vacuum to be switched off to perform the filter cleaning operation.
- PULLCLEAN: the filter can be cleaned while the vacuum is running, you only have to close the inlet and pull the flap several times.
- INFINICLEAN: it is completely automatic and stand-alone and cleans the cartridges filter while the vacuum cleaner is working.
- PULSE JET SYSTEM: it is completely automatic and powerful and it needs to be supplied with compressed air.
