Introduction

Application

Mini Pleat filter element type MFE for the separation of fine dust and suspended particles such as aerosols, toxic dusts, viruses and bacteria from the supply and extract air in ventilation systems with large volume flow rates and the requirement for long filter life
Fine dust filter: Prefilter or final filter for the separation of fine dust in ventilation systems.
Particulate filter: Main or final filter used for the most critical requirements of air cleanliness and sterility in areas such as industry, research, medicine, pharmaceuticals, and nuclear engineering

Special characteristics

Leakage test, standard for all particulate filters of filter class H13

Classification

Eurovent certification for fine dust filters

Nominal sizes

B × H × D [mm]

Description

Construction

GAL: Frame made of galvanised steel
AL: Frame made of aluminium

Accessories

Adhesive tape for sealing off the filter elements, width: 19 mm, length: 55 m
One roll suffices for about 50 filter elements of size 600 × 65 × 202 mm, for about 100 filter elements of size 86.5 × 202 × 600 mm, or for about 70 filter elements of size 86.5 × 303 × 600 mm
Order number: ACC-AT

Construction features

Compact wedge design
The filter elements are joined together by a special adhesive tape which also provides an air-tight seal between the filter elements and the mounting frame or installation casing
The special adhesive tape for sealing off the filter elements must be ordered separately

Materials and surfaces

Filter media made of high-quality, moisture-resistant glass fibre papers, pleated
Spacers provide a uniform spacing of the pleats
Joint sealing compound made of permanently elastic two-component polyurethane adhesive
Frame made of either galvanised sheet steel or aluminium

Standards and guidelines

Test according to ISO 16890; international standard for general room air distribution; classification of arrestance efficiency based on the measured fractional arrestance efficiency, which is processed into a reporting system for the fine dust arrestance efficiency (ePM)
For fine dust filters, the fractional arrestance efficiency of a certain size range is determined by aerosols (DEHS and KCl)
The filters are classified into filter group ISO aPM1 depending on the tested values
Testing of particulate filters to EN 1822 (EPA, HEPA and ULPA filters): European standard for the testing of filtration performance in the factory, particle counting method using a liquid test aerosol
Uniform classification of particulate filters according to efficiency, using a test aerosol whose average particle size lies within the minimum efficiency (MPPS)
Particulate filters are classified according to the values determined for the local filtration efficiency and the overall filtration efficiency as EPA (filter classes E10, E11, E12), HEPA (filter classes H13, H14) or ULPA (filter classes U15, U16, U17)
Hygiene conformity: VDI 6022, VDI 3803, DIN 1946 Part 4,ÖNORM H 6020, SWKI VA 104-01 and SWKI 99-3 and EN16798

Specification text

Mini Pleat filter elements MFE for the separation of fine dust and suspended particles such as aerosols, toxic dusts, viruses and bacteria from the supply and extract air in ventilation systems. Use as fine dust filters, i.e. as pre-filters or final filters in ventilation and air conditioning systems; or as particulate filters, i.e. main or final filters for the most critical requirements of air cleanliness and sterility in areas such as industry, research, medicine, pharmaceuticals, and nuclear engineering. Large volume flow rates and long filter life due to the very compact, modular structure. Filter media of high-quality, moisture-resistant glass fibre papers with spacers. Low initial differential pressure due to ideal pleat position and largest possible filter area. Mini Pleat filter elements available in market sizes, filter groups ISO ePM1 (fine dust filter) and EPA, HEPA (particulate filter). The filter elements are joined together by a special adhesive tape which also provides an air-tight seal between the filter elements and the mounting frame or installation casing. The special adhesive tape must be ordered separately. Mini Pleat filter elements used as fine dust filters are certified by Eurovent. Mini Pleat filter elements MFE hygienically conform to VDI 6022.
