Construction features

• Casing with robust, doubled-edged connecting flanges with pre-drilled holes.
  
  
• Automatically adjusting clamping mechanism which guarantees sealing integrity between the casing and the filter element; this clamping mechanism can only be closed when the filter element is properly seated
  
  
• Cover plate with profiled seal and 4 clamping screws with star grips
  
  
• Prefilter casing for fitting Mini Pleat filter panels as fine dust filters
  
  
• Double-groove service board and plastic service bag for contamination-free filter change
  
  
• Sealing integrity test facility for Mini Pleat filter panels as particulate filters
  
  
• Casing with indentations to ensure the precise fitting of the filter elements
  
  
• Leakage classes D according to EN 15727 and L1 according to EN 1886
  
  
• Leakage test for each individual casing

Materials and surfaces

• Casing made of sheet steel, powder-coated RAL 9010, pure white, or of stainless steel
  
  
• Stainless steel clamping mechanism

Installation and commissioning

• Installation orientation: horizontal or vertical (rotated by 90°)
  
  
• Pressure measurement points for each filter unit are part of the supply package but must be set up on site by others

Standards and guidelines

• EN 15727; Ventilation for buildings – Ducts and ductwork components, leakage classification and testing
  
  
• EN 1886; Ventilation for buildings – Air handling units – Mechanical performance
  
  
• ATEX Directive 2014/34/EU

Maintenance

• Filter change: Ejection mechanism for the easy removal of the filter elements from the filter casing
