A-Mist40 / 80TF Centralized Oil Mist Filters with Fan
Part No. A-Mist40 / 80TF Centralized Oil Mist Filters with Fan
The Absolent type A-mist Oil mist filter features one of the most effective systems in the world for cleaning oil mist. The series of central filter units consists of parallel modules which are dimensioned after the needed air-flow. The advantages of central filters are a cheaper installation, easier service because of less service points and the possibility to lead the process air through a heat exchanger. Lead for example the process air outside during summer and back into the premises at winter time.
Having the highest possible collecting efficiency, the filtered air becomes so clean that it usually can be returned to the premises. This means less loss of energy and a more balanced ventilation.
Absolent filter units are extremely low maintenance and can usually run for at least one year without requiring a filter change. Moreover, A-mist filter cassettes can usually be washed (does not apply for the HEPA filter. This results in a low total cost of ownership.
The fan, as the only moving component, is placed at the clean-side to minimize wear & tear.
Product Details
The filtering process occurs in three stages. The first and second stages consist of self-draining Absolent filter cassettes. The third stage consists of a HEPA-filter, which has a guaranteed and consistent collecting efficiency of 99.99% arresting 0.3μm dia. particles.
The filter unit has an electronic pressure gauge, A-monitor, which shows the pressure drop over the different filter stages and indicates when a filter cassette is to be changed. Thanks to the continuous draining of the filter cassettes, the unit can be operated without interruptions. The return oil is collected at the bottom of the filter for recycling.
