3M CUNO DuoFlo - 4 times longer life
 |
Cuno DuoFLO are made to optimize a company's production to their fullest. This is done by designing a unique filter that has a 62% stronger fitler surface, it means that the filter can be used 4 times as long as a normal filter, it minimize The number of times before replacing the filters.
Cuno DuoFLO is built around a two-layer bag filter, this filter makes the outer side of the filter stands for the coarse filtration, and the inside is responsible for the fine filtration. Cuno (3M) specializes in creating the future of safe filtration idne for bag filtration. The picture below shows a model of how Cuno DuoFLO filter works, from left comes the dirty air, it is shown in red to show it is dirty, the meetings so coarse filter here after a fine filter. responding to the pure liquid on the right (marked green)
DuoFLO filter housing is built with a unique locking system to the filter, this makes it easy for the installer to replace the filter, it can now do without tools. This makes the filter changed Staf take place quickly and cleverly, it will mean that there will be a minimal production down-time when the filter is changed.
