Grease cassette filters – reliable grease filtration for ventilation systems
Grease cassette filters are metal air filters designed for the effective removal of grease, oil vapours and fatty impurities from exhaust air. They are an essential component in ventilation systems where air is contaminated with grease particles, particularly in commercial and industrial kitchens.
By capturing grease and oily contaminants at an early stage, grease cassette filters protect ventilation ducts, fans and equipment from contamination, reduce maintenance requirements and contribute to safer system operation.
Filtration principle and construction
Grease cassette filters are constructed from a rigid metal frame filled with multiple layers of braided metal mesh. The mesh layers are enclosed on both sides by a reinforcing metal grid, either drawn or welded, ensuring mechanical stability and long service life.
As grease-laden air passes through the filter, grease particles collide with the metal mesh layers and are retained within the structure. The large filtration surface allows efficient separation of grease and impurities while maintaining stable airflow.

Easy cleaning and regeneration
Grease cassette filters are designed for easy maintenance.
Collected grease accumulates in dedicated chambers within the filter structure and can be removed during cleaning.
The filters can be regenerated by washing with detergent water, preferably under pressure, restoring filtration performance and extending service life. This makes grease cassette filters a cost-effective and sustainable solution for grease filtration.
Typical applications
Grease cassette filters are widely used in environments where grease and oil vapours are present, including:
-
Commercial kitchens and restaurants
-
Industrial catering facilities
-
Food processing plants
-
Production environments involving fats and oils
-
Wood processing industry, where oily and greasy contaminants occur
In gastronomy, grease cassette filters play a critical role in fire risk reduction, hygiene improvement and protection of ventilation systems.
System integration
Grease cassette filters are typically installed in exhaust ventilation systems, such as kitchen hoods and extraction units, as the primary filtration stage for grease-laden air.
