EW-F48 Series Automated Filter Integrity Tester

The EW-F48 automated filter integrity tester is a microcomputerized, intelligent, and high-sensitivity precision analysis instrument independently developed by Hangzhou Eternalwater Filtration Equipment Co., Ltd. It is specially used to test the integrity of filter cartridges or membranes in filtration systems. The instrument enables a variety of standard functions, including forward flow test, bubble point test, water intrusion test, combined test of forward flow and bubble point , etc. At the same time of testing, the instrument can automatically perform self-test, automatically control the stabilization time and test time, store and print the current test results, etc.; historical data is displayed graphically to reflect changes in test time and gas flow rate more intuitively.

Product features
1.High-performance CPU, touch screen design, simple,fast and reliable operation.
2.Powerful storage function, data can be queried at fixed points or under specific conditions, and the built-in printer can quickly print test results, historical data, and real-time data curves.
3.The test speed is fast.
4.Small size, light weight, low energy consumption and easy to carry.
5.Splash-proof technology IP54 specially designed for production environments.

Industry Application
1.Pharmaceutical industry: Integrity test of various hydrophilic and hydrophobic filters, including pleated filter cartridges, capsule filters, flat filter membranes, and membrane bags.
2.Food industry: filters for alcohol, mineral water and drinking water.

Integrity Tester Precautions

1.The gas tightness of the instrument and system.
2.The sealing of the filter cartridge end cap and filter socket.
3.For bubble point and forward flow, please pay attention to whether the filter cartridge is completely wetted, and water intrusion requires that the filter cartridge is strongly hydrophobic and dry.
4.Determine the type of filter cartridge. Only absolute membrane filter cartridges can be tested for integrity, such as PES, PTFE, PVDF, NY66, etc.
5.The gas pressure needs to be at least 1000mbar higher than the test bubble point.
