Compact filters – high-efficiency air filtration where air quality is critical
Compact filters are high-efficiency air filters designed for ventilation and air conditioning systems where air quality is critical. They effectively remove fine airborne contaminants such as smoke, vapours, pollen, bacteria and other microscopic particles.
Compact filters are used wherever a high level of air purity is required, both in comfort ventilation and in industrial or technical environments. Depending on system design, they can function as high-performance filters in ventilation systems or as final filters in applications with elevated air cleanliness requirements.
Filtration performance
Compact filters are capable of capturing particles several hundred times smaller than the width of a human hair. This makes them suitable for environments where reliable fine particle control and consistent air quality are essential.
They are available in filtration classes E10, E11, E12 and H11, allowing accurate selection based on air quality requirements and system performance.
Filter media and construction
Compact filters are based on a minipleat glass fibre filter medium. This construction provides a very large effective filtration surface within a compact housing.
The pleated glass fibre structure ensures:
-
high filtration efficiency
-
long service life
-
stable airflow characteristics
-
consistent performance under varying operating conditions
The robust design allows compact filters to withstand intensive airflow and demanding operating conditions without loss of performance.
Available construction variants
Compact filters are available in three construction variants to suit different installation and handling requirements.
Standard compact filter
Compact minipleat filter without additional accessories, suitable for general high-efficiency air filtration.
Compact minipleat filter with flange
Equipped with an integrated mounting flange to improve sealing and ensure reliable, leak-free installation.
Compact filter with protective grid
Fitted with a protective metal grid to increase mechanical strength and protect the filter media during operation and handling.
