EMW compact filters deliver maximum filtration efficiency with minimal pressure drop. They are ideally suited for HVAC systems, industrial applications, and high-purity air processes. Available as fine particulate filters or particulate air filters in all common filter classes according to ISO 16890 (formerly EN 779) and EN 1822 / ISO 29463.
EMW® minipleat compact filters are predominantly used in Heating, ventilation and air conditioning (HVAC), laboratories, and workplace extraction systems. For gas turbine air intake filtration, we offer specialized GT compact filters.
The precisely formed minipleat technology and robust hot melt pleat fixation ensure maximum filter performance and long-term structural stability – even at high volumetric flow rates. Premium, wet-laid fiberglass media guarantee consistently excellent air purity.
Thanks to their large filtration area within a compact space requirement, compact filters provide high-performance filtration even in space-restricted installations.
Many operators of HVAC (RLT) systems continue to select pocket filters or panel filters. However, especially in continuous operation, these filter types exhibit significant drawbacks:
Compact filters represent a substantially more robust, energy-efficient, and durable alternative:

Standard dimensions:
Other sizes available upon request.
When optimizing energy consumption, service life, or pressure differential.
More filtration area → lower load → longer service life and reduced energy demand compared to bag or panel filters.
Yes – high-efficiency, water-repellent media with low pressure differential, integrated into a compact design offering large filtration area.
Yes, standard dimensions are available and compatible with existing installations.
Required filter class depends on outdoor air quality (ODA) and indoor air requirements (SUP zone). Request detailed guidance for optimal filter selection.
