Air Filtration for Buildings

Filter elements

Systematic air hygiene for complex requirements.

Solutions using filters from DELBAG® Air Filtration ensure a 100% success for all tasks. One reason is because our comprehensive filter program enables a complete filtration – exactly tailored to any individual requirement, and in addition, we combine this offer with the minimum and energy-saving pressure drops. Another reason is that DELBAG® Air Filtration systems are constructed so that interior dirt and microbe pockets cannot develop from the very beginning.

The filter elements are characterized by the following features:

  • High filtration surface enables low pressure drop
  • Special fold geometry is suitable for turbulent air flow volumes
  • Very robust construction for highest demands
  • Best energy-efficiency classes for reduction of electric power consumption
  • Space-saving design for short filter chambers

Product variants

MultiForm Eco

MultiForm Eco

In the production of the DELBAG® MultiForm Eco, the filter medium consisting of microfiberglass paper is folded, thus forming an extremely stable pleat pack. The number and height of the individual pleats is optimally adapted to the respective area of application. The pleats are arranged in a V-shape (in 3 compartments) within an ABS frame. To enable this high stability and airtightness, the individual pleat packages are glued to the frame.

  • Large filtration surface ensures low pressure losses

  • The special pleat geometry can also be used with turbulent air flows

  • Low installation depth

  • Applications: offices, educational facilities, retail, multi-story car parks

  • Areas of application: standard climate control facilities and air handling units, photographic, electrical and food product industry, high value assembly room and switchgear facilities

  • Areas of application: hospitals, pre-filtes for clean-room facilities

  • All three filter classes of MultiForm Eco are equipped with a condensate drip tray and handles for easy on-site transport

  • Variants: MultiForm eco 55 (ISO ePM2.5 50%), MultiForm eco 65 (ISO ePM2.5 60%), MultiForm eco 85 (ISO ePM1 50%), MultiForm eco 95 (ISO ePM1 80%)

MultiForm Plus

MultiForm Plus

DELBAG® MultiForm Plus filter elements are made of microglass paper which is pleated to form a stable package of folds. The number and the height of the folds are optimally designed to match operating conditions. Peripheral but merged synthetic strips keep individual pleats at a distance along the entire pleat depth and ensure greater stability and complete utilisation of the entire filter surface. The individual filter plates are arranged in a V-shape (in 4 compartments) inside a synthetic frame made of ABS, so as to assure a stable form of the filter plates, and are fully bonded to assure air-tightness. The compact filter elements are fitted with a large filtration surface and a robust burst protection on the clean aire side to ensure operational saftey even under toughest conditions.

  • Large filter surface ensures low pressure loses

  • 400 mm installation depth, ideal for compressors and air intake system

  • Extremly durable due to fully cast filter pack

  • Applications: off-shore plant, protection of gas turbines, compressors, energy generation
