Filter elements are meticulously crafted in diverse shapes and configurations to elevate filtration efficacy in a vast array of applications, from automotive to industrial fluid management. These elements are renowned for their resilience against elevated temperatures and their capacity to handle substantial differential pressures. Manufactured from materials such as SS 304, SS 316, and SS 316L, they are available in both the classic cylindrical form and a pleated variant to expand the filtration area. To bolster their longevity and safeguard against damage under fluctuating operational conditions, every stainless steel pleated and cylindrical filter is fortified with a more coarse media layer. The integrity of these elements is assured through bubble point testing, which confirms the absence of any openings exceeding the specified pore size, especially at critical junctions or seams. Characterized by their durable stainless steel make, these filter elements resist media migration, are conducive to backwashing, and can be reused, thus enhancing operational efficiency and promoting sustainability.
