DELTAFILTER Filtrationssysteme GmbH

DELTA-HS hat sieves (start-up sieves)

Hat strainers, the solution for the filtration of liquids and gases, are characterized by their suitability for installation between two flanges. They serve as permanent protection or during the commissioning of systems. As so-called police filters, they are ideally suited for use in situations where not too large quantities of dirt need to be intercepted. These screen types are made of high-quality stainless steel, which gives them high durability and longevity even under demanding operating conditions. A major advantage of hat strainers is their minimal space requirement thanks to their compact design. This makes them ideal for applications where available space is limited and efficient use of space is required.

To extend their range of applications, hat strainers are optionally available with special finenesses, larger nominal diameters, higher pressure ratings, special sealing surfaces and versions for ANSI flanges. These options allow greater flexibility and adaptability to specific operating conditions and requirements. Customized designs of hat screens are also possible, allowing precise adaptation to individual requirements and specific operating conditions. This ensures that the screens are precisely matched to the respective applications and processes.

Overall, hat strainers offer a versatile, space-saving and efficient filtration solution for a wide range of applications in the filtration of liquids and gases. Their robustness, adaptability and ability to meet customer-specific requirements make them a valuable option for various industrial filtration needs.
