About us


For many years Elfi has been committed to the design, construction and control of filtration systems with self-cleaning filters, cartridge filters, strainer filters and centrifugal separators for fluids in various applications.

From its inception, the company has attracted competencies in the area of design and construction of self-cleaning filters with expertise in the design of water treatment processes: this has enabled us to effectively study and develop products that can meet all the requirements of a modern water treatment process.


Our company produces filtering systems with a variety of materials in order to meet any kind of process need. Our standard production focuses on the most frequent filtration degrees for application in self-cleaning filtration from 500 μm to 25 μm.There is an increasing number of applications requiring filters that can operate even below these values down to 1÷2 μm. These cases call for careful engineering of the application to enable adequate sizing of the system and achieve excellent performance.Our company also specializes in the construction of customized filtration systems providing highly competitive solutions for any industrial application and in line with every customer’s specific requirements.
