There are various filter element interface types available, each suitable for different applications and filter elements. These include threaded interfaces such as M20, M30, M36, and M42, plug-in interfaces like 215, 222, and 226, as well as quick-release and elastic interfaces. Additionally, certain filter elements use a double open end (DOE) interface for specific connections.

M20

M30
M20 Connector: The M20 connector is a threaded connection featuring a 20mm diameter thread. It typically consists of a male threaded portion on the filter cartridge or housing, along with a corresponding female threaded portion. Nuts and washers can be used for secure connection, ensuring stability and preventing leaks. This connector is commonly used in water treatment systems, liquid filtration, and gas filtration when connecting filter cartridges and housings.
M30 Connector: The M30 connector is another threaded connection with a 30mm diameter thread. Similar to the M20 connector, it involves a male threaded portion on the filter cartridge or housing and a corresponding female threaded portion. Nuts and washers are used for installation and secure connection. The M30 connector is commonly used for filter cartridges and housings in various liquid and gas filtration processes.

M36

M42
M36 Connector: The M36 connector is a threaded connection with a 36mm diameter thread. It is often employed for connecting large-scale filter cartridges, high-flow filters, and industrial filtration applications, providing high-capacity flow processing capabilities.
M42 Connector: The M42 connector is a threaded connection with a 42mm diameter thread. It is commonly used in industrial filter cartridges and large-flow filtration systems, suitable for filtering and processing larger particulate matter.

215

222
215 Connector: The 215 connector is an insert-type connection named after the 2.15-inch (approximately 54.6mm) diameter of the filter cartridge. This connector is typically used for filter cartridges and housings in water treatment and liquid filtration industries.
222 Connector: The 222 connector is an insert-type connection with a filter cartridge diameter of 2.22 inches (approximately 56.4mm). It is commonly used in liquid and gas filtration applications, including microbial filters and high-efficiency filter cartridges.

226

DOE
226 Connector: The 226 connector is an insert-type connection with a filter cartridge diameter of 2.26 inches (approximately 57.4mm). Similar to the 222 connector, it is widely used in liquid and gas filtration, suitable for high-efficiency filter cartridges and microbial filters.
DOE Connector: The DOE (Double Open End) connector is a common type of filter cartridge connection where both ends of the filter cartridge are open. The DOE connector is commonly used for filter cartridges and housings in various industries such as water treatment, food and beverage, chemicals, and pharmaceuticals.
