VARIO – Separation of fine dust particles The VARIO series is particularly suitable for separation of fine dust. The VARIO units are of modular construction in order to meet different requirements, such as dust characteristics or the volume of exhausted air.

Separation of fine dust 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 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. Mechanical and thermal...

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 The filter elements are of high quality and are available in a...

Waste disposal and safety Waste disposal Standard: The air-tight and dust-tight For larger dust volumes or in 24-hour disposal bins are connected to the operations, the waste disposal is filter's hopper with a clamping device, continuous via rotary valves, into simplifying the exchange of dust col- disposal tanks or Big Bags. Further lector containers. alternatives are available - gate valve (optional) - rotary lock Safety It is possible to equip the VARIO units with security technology if combustible or explosive dusts are created during Explosion suppression by automatic entry of ProFlap...

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 Air recirculation is often possible with the use of high-quality SINBRAN 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 accomplished by activating a switch within...
