  • Application
  • Description

Application

  • Mini Pleat filter panel with hood, type FHD, for the separation of suspended particles such as aerosols, toxic dusts, viruses and bacteria from the supply and extract air in clean room systems with controlled air cleanliness and airflow
  • Particulate filters: Final filters for the most critical requirements of air cleanliness and sterility in areas such as industry, research, medicine, pharmaceuticals, and nuclear engineering

Special characteristics

  • Ideal pleat geometry of the filter medium
  • Low-turbulence airflow on the downstream side
  • Leakage test, standard for all particulate filters of classes H13, H14, U15

Filter classes

  • Particulate filters E11, H13, H14, U15

Construction

  • Without centre mullion, spigot with fixed baffle plate
  • D: Centre mullion with pressure measurement point on the downstream side, spigot with fixed baffle plate
  • R: Centre mullion with pressure measurement point on the downstream side, spigot with adjustable baffle plate for volume flow rate balancing
  • V: Centre mullion with pressure measurement point on the downstream side, spigot with damper blade for volume flow rate balancing

Options

  • D: Spigot diameter
  • PD: Protection grid on the downstream side
  • SD: Stainless steel protection grid on the downstream side
  • SPD: Perforated stainless steel face plate on the downstream side
  • APD: Perforated aluminium face plate on the downstream side
  • FND: Flat section seal on the downstream side
  • WS: Without seal
  • OT: Oil mist test (only for filter classes H13, H14)
  • OTC: Oil mist test with certificate (only for filter classes H13, H14)
  • ST: Scan test (only for filter classes H13, H14, U15)

Construction features

  • Hood with top entry circular spigot
  • Spigot diameter available in commercial sizes
  • Some constructions are fitted with an optional flat section seal on the downstream side
  • Protection grid on downstream side: expanded metal grid or stainless steel
  • Perforated stainless steel or aluminium face plate on the downstream side

Materials and surfaces

  • Filter media made of high-quality, moisture-resistant glass fibre papers, pleated
  • Spacers made of thermoplastic hot-melt adhesive provide a uniform spacing of the pleats
  • Joint sealing compound made of permanently elastic two-component polyurethane adhesive
  • Frame made of extruded aluminium sections
  • Hood with spigot made of galvanised sheet steel

Mini Pleat filter panels with hood, type FHD, for the separation of suspended particles such as aerosols, toxic dusts, viruses and bacteria from the supply and extract air in clean room systems with controlled air cleanliness and airflow.

Use 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.

Mini Pleat filter panels with hood, consisting of an extruded aluminium frame, filter medium, and a hood with top entry circular spigot; filter media made from high-quality, moisture-resistant glass fibre papers with spacers made of thermoplastic hot-melt adhesive.

Low initial differential pressure due to ideal pleat position and largest possible filter area. Filter hood available in various sizes and the usual grid sizes, filter classes E11, H13, H14 and U15.

Optional flat section seal and protection grid on the downstream side. Choice of expanded metal, powder-coated (RAL 9010) protection grid, stainless steel protection grid, or perforated plate made of stainless steel or aluminium.

Mini Pleat filter panels from filter class H14 are subjected to an automatic filter scan test.

Special characteristics

  • Ideal pleat geometry of the filter medium
  • Low-turbulence airflow on the downstream side
  • Leakage test, standard for all particulate filters of classes H13, H14, U15

Materials and surfaces

  • Filter media made of high-quality, moisture-resistant glass fibre papers, pleated
  • Spacers made of thermoplastic hot-melt adhesive provide a uniform spacing of the pleats
