VARIO eco
8Pages

For the highly effective, energy efficient dry separation of fine, free-flowing dust The VARIO eco series is characterized by its low filter resistance with very high separation efficiency. The VARIO eco units are of modular construction in order to meet different requirements, such as dust characteristics or the volume of exhausted air.

Keller Lufttechnik plans, engineers and fabricates systems to keep air clean in all industrial sectors in which air pollutants are collected, transported and separated. Innovative filter technologies and a systematic equipment design ensure optimal separation results. The VARIO eco series is particularly suitable for separation of fine dust. Nearly all types of dust can be successfully separated, such as those created in metal processing, polymer processing, and in chemical, pharmaceutical and ceramic industries, as well as non-metallic minerals. The VARIO eco units are of modular...

The dust-laden air flows through the dirty air inlet into the filter unit. A baffle plate slows down and deflects the dust particles to protect the filter elements from direct impact. An air down-flow is created between the filter elements, allowing the dust par- ticles to drop. A fan in the clean air chamber draws the polluted air through the filter elements, depositing the dust particles onto the filter surface. Because the filter elements are cleaned continuously by compressed air pulses during operation, Filter elements Cartridges or plate filters are used, depending on the application,...

Waste disposal and safety Waste disposal For larger dust volumes or in 24-hour operations, the waste disposal is continuous via rotary valves, into disposal tanks or Big Bags. Additional alternatives are available. Waste disposal 1 - gate valve (optional) - 220-liter container Standard: The air-tight and dust-tight disposal bins are connected to the filter‘s hopper with a clamping device, simplifying the exchange of dust collector containers. Waste disposal 2 - rotary lock - Big-Bag/container It is possible to equip the VARIO eco units with security technology if combustible or explosive...

Flexible solutions The direct-drive radial fan is very silent. Depending on the size of the filter unit, the fan is either integrated, topmounted or placed next to it. Installation outdoors is possible if weather protection is provided and is within noise limit requirements. Venting outdoors of re-circulation Clean air return (return air) is usually feasible during separation with our high quality filter elements. The cleaned air can be ducted and channeled (even with heat exchangers) to the outdoors, or re-circulated back into the workplace. Alternate venting or recirculation can be...
