LFK Extraction Arms

LFK U Extraction Arms

Our HFH LFK U portable filter system is a perfect fit for environments where protection against viruses is absolutely essential, such as dental clinics, healthcare facilities and laboratories in the UK.

OVERVIEW

The HFH 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.

The 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, the LFK U is equipped with a highly efficient filter (ULPA 15 rating), an optimised 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 available in the HFH range of products.

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.

The 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 Penetra- ting Particle Size) method with a size of 0.17 μm, which is the most difficult size for a filter to cap- ture. For smaller or larger particles, the filter has higher separation 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 fil- ter efficiency is reduced. The 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 every 6 months.
