BFSK - Silica Gel Air Filter

Nominal size: 45/21, 60/21, 90, 130
Maximum flow: 2000 l/min

Application

  • Filtration and dehumidification of the intake air of industrial systems.
  • Avoidance of initial damage in pumps and bearings and system components.

Design

Water Collection in Tanks: Most liquid tanks must also allow for the exchange of air. They must be able to breathe. Depending on the machine cycles, air is sucked into the tank and pressed outwards again. This air contains small miniature particles and also water vapor. Due to different temperatures in the tank, the water vapor condenses. The resulting water promotes the oxidation process of the oil and is also responsible for possibly occurring damage at the gears and machines. Due to the catalytic influence of solid metallic parts, this process is further accelerated.

Filtration and Drying in One Single Process: Through the BRFS silica gel air filter, gear and tank are able to breath clean and dry air. The sucked in air is firstly dried by means of Z-R granulate. Afterwards, the air streams through the pleated filter element where the solid dirt particles are collected. In this way, only dried and filtered air reaches gear and tanks. The air coming out of the system can enter the atmosphere in the opposite direction.

Monitoring: The Z-R granulate's absorption capacity regarding humidity becomes visible by a change in color from dark red to orange. An optional clogging indicator shows how much filter capacity has already been used and how much is still available.
