Please inform us the detail of the environment

Different environments decide different filter bags. In order to ensure that the accident will not happen to choose the most suitable filter bag for the environment is particularly important. Temperature, humidity, PH, gas composition and so forth, the more detail the better. Our client manager prepared a questionnaire, just fill it then we can give you the suitable products.

Ensure standardized installation

Meanwhile, the installation process is also particularly important, non-standard installation is a major cause of accidents. Be sure to check the situation after the filter bags installed.
