Filter casings for duct installation

Universal casings for duct installation in single or two-stage construction for pocket filters, Mini Pleat filter panels and filter inserts, activated carbon filter inserts or cartridges

• Highly variable due to different dimensions and space saving, compact casing sizes
• Fitting of particulate filters and/or activated carbon filters in one casing depending on application
• Side maintenance cover with handles and star grip screws for simple filter change (arrangement left or right in airflow direction)
• Optimum sealing when inserting the filter elements due to a foamed, closed cell endless seal of the standard cell frames mounted in the universal casing.
• Simple insertion of the filters into a standard cell frame with 4 spring clips
• Quick installation without additional attachments
• Casing is supplied fully assembled; from size 3.5 × 3.5 (2245 × 2245 mm), the casing is supplied disassembled as a compact container

Optional equipment and accessories

• Stainless steel construction

Ducted HEPA filter for Mini Pleat filter panels, Mini Pleat filter cells and activated carbon filter cells. For installation into the ductwork of ventilation systems.

• Duct casings made of sheet steel with decontaminable powder coating RAL 9010
• Robust, welded casing construction with perimeter connecting flanges with pre-drilled holes
• Casing with indentations to ensure the precise fitting of the filter elements
• Secure sealing between the casing and filter element due to turnbuckles
• Robust cover plate with profiled seal, 4 clamping screws, and a handle for air-tight closure
• Horizontal or vertical installation orientation

Optional equipment and accessories

• Stainless steel construction

Ducted particulate filter for Mini Pleat filter panels, Mini Pleat filter cells, and activated carbon filter cells. For installation into the ductwork of ventilation systems. Used in medicine, biology, the pharmaceuticals industry, and sensitive technical areas.

• Ducted particulate filter made of sheet steel with decontaminable powder coating RAL 9010 and clamping mechanism made of stainless steel
• Robust, welded construction with doubled-edged perimeter flanges with pre-drilled holes ensures secure sealing
• One-stage or two-stage casing, for the fitting of fine dust filters as prefilter stage and of particulate filters as second filter stage
• Secure sealing and convenient handling due to tensioning lever for a consistent contact pressure and hence sealing integrity between the casing and filter element
• With sealing integrity test facility for filter elements

Optional equipment and accessories

• Optional double-groove service board for contamination-free filter change (‘safe change’)
• Plastic service bag with O-ring for contamination-free filter change
• Explosion-proof construction for protection zones 1 and 2, as well as 21 and 22

Spigot for assembling filter unit systems in ductwork

• Spigots made of sheet steel with decontaminable powder coating RAL 9010
• Air deflection plates in the air outlet spigot ensure a uniform airflow through the system, reduce the total differential pressure, and lower energy costs
• For filter unit systems of up to 6 filter casings in a row
• Leakage test for the entire filter unit system

Optional equipment and accessories

• Stainless steel construction

Duct casing for Mini Pleat filter panels, Mini Pleat filter cells, and activated carbon filter cells. For installation into the ductwork of ventilation systems

• Highly variable due to different dimensions and space-saving, compact casing sizes
• With side service door for easy filter change
• Easy handling and secure sealing due to clamping mechanism
• Clamping mechanism for easy filter change and secure, air-tight assembly
• Quick installation without any requirement for additional attachments since the casing frame is used as connecting frame
• Delivery as fully assembled unit

Optional equipment and accessories

• Clamping screw with star grip for the service door
