TECU is a modular filter designed for suction and collection of fumes and dust generated by sheet metal processing machines. The filter consists of a stand-alone unit with dust collecting hopper and integrated fan, a polygonal shaped casing, horizontally inserted filter elements, and a reverse air jet cleaning system.

Function
The dirty air flow enters the filter casing from the top inlet flange or from the spark trap where sparks and heavier particles are pre-separated.
Thanks to negative pressure generated by the fan, the aspirated fumes are forced through the filtering elements which collect the pollutant and let clean air exit into the environment.
Dust drops down into the dust collecting hopper after an automatic reverse air jet cleaning device has removed it from the filter elements.
Thanks to its modular structure, a large variety of configurations is possible in terms of both filter surface area and filter assembly.
TECU can also be supplied as an integrated system for dust recovery including the RECOFIL recovery device and the EASYFILL bulk bag filling and storage equipment (see related pages). This package automates dust disposal in a clean and health-protective manner. The system radically reduces maintenance costs versus traditional solutions avoiding any plant downtime offering a very short pay back.
