Portable filter system with the highest filter rating (ULPA) for virus filtration

Portable filter system for environments where protection against viruses is essential, e.g. dental clinics, healthcare facities and laboratories. FUMEX LFK U is an effective and flexible solution consisting of a fan, filter and fume extractor in a single unit. It is highly suitable for use in healthcare environments where exhaled air, which could potentially contain viruses or residues from inhaled medicines, can be problematic.

Virus filtration

Viruses in dry form have a size of 0.08-0.12 µm but are usually bound to an aerosol and are therefore almost always larger. A ULPA filter is very good at filtering these particles. Fumex LFK U has an ULPA filter (FPU 50) as stan-dard. The filter is rated ULPA 15 and tested in accordance with EN 1822-1 and has a separation efficiency >99.9995%. The filter is tested using the MPPS (Most Penetrating Particle Size) method with a size of 0.17 µm, which is the most difficult size for a filter to capture. For smaller or larger particles, the filter has higher sepa-ration efficiency. The filter test is carried out at flow of 100 m³/h (28 l/s) per m² filter area. At higher flows per m², the filter efficiency is reduced. Fumex FPU 50 has a filter area of 5 m² and can thus tolerate a flow of up to 500 m³/h without diminished separation efficiency.

The FPU 50 filter should be replaced once a year.

Fumex LFK U is available in two versions

LFK 150U with a Ø50 mm extractor arm, and LFK 175U with a Ø75 mm extractor arm. LFK U works according to the low-vacuum principle, which entails a very low risk of filter failure, produces little noise and has low power requirements.

For maximum efficiency, Fumex LFK U is equipped with a highly efficient filter (ULPA 15 rating), an opti- mised fan with a highly efficient EC motor with speed control and a flexible ME extractor arm, which featu- res the lowest pressure drop on the market.

Among the accessories is the LF TR, a portable trolley on lockable wheels with bracket for the ME extractor arm. LF TR is compact and easily blends into the work environment.

The fan and filter can be combined with other extractors avaliable in Fumex range of products.
