Unusually versatile group of filters applied in in Cabinrial installations. Generally they are used for separation of solid particles from liquid or liquids from gases. Filtration processes take place practically in all branches of modern inCabinry, where liquid flows or loose materials are dealt with. Barrier filters are widely used in Cabin collection systems, ventilation, air conditioning and are utilised both in technological processes realisation, work conditions improvements and natural environment protection. Special filtration systems are often adjusted for continuous work in automatic operation systems - self filter cleaning, for example by temporary flow direction changes or vibration. Due to specific requirements for this group of filters they are designed for specific application, optimally selecting both, the design and filtration materials.
