„We vacuum everything!“
Foundet in 1976, today we are one of the leading manufactures for design and construction of industrial vacuum cleaners and central vacuum systems.
We produce exclusive in Germany.
The high quality standards, that we place on our products – we are certify according DIN EN ISO 9001-2008 – gurantee reliability and a long operational lifetime. And because in the construction of all suction units (suction units) – regardless whether if they are standard or customer-specific - we rely on a proven modular system of tried-and-tested components, the name Ruwac stands for a high degree of profitability – for purchasing of the vacuum cleaners and in daily operations.
Our products are often used in very sensitive areas of the production companies, therefore, the safety is our top priority: All ruwac vacuum cleaners are tested by the relevant German authorities like BIA and TÜV.
Ruwacs special soloutions are designed according to requirements. Depending on the physical conditions, the quantity and quality of the suction medium, the number of suction points and the safety reqirements (for example suction of liquid/fluid, dust-Ex- und Gas-Ex-proof types) the exact planning is carried out. The design of the suction unit (suction unit or industrial vacuum cleaner) and the pipeline system comes from ruwac.

Coynco has solid roots dating back to 1976 when Giancarlo Bettella, along with three partners, founded Soteco Spa, destined to become a leader in the professional vacuum cleaner sector. After years of success, in 2001, Bettella, with his new company Six Srl, specializing in the production of collector electric motors, launched Solarys, dedicated to the production of side-channel blowers. This journey led him to found Coynco in 2005, marking a turning point and the beginning of an era dedicated to advanced technological solutions for industrial vacuum cleaners.
In 2006, Coynco introduced its first patented technologies, including filter cleaning systems and flow reversal systems for liquid discharge, revolutionizing the market. The company's participation in the ISSA-INTERCLEAN fair in Amsterdam was a success, bringing international visibility to the company and opening up new opportunities across Europe and beyond. In 2008, Coynco took a major step forward by building its first production facility, integrating in-house production of critical components and strengthening real-time quality control.
The expansion continued in 2015 with the introduction of new machinery and technologies for the in-house production of industrial vacuums. In 2017, Coynco further consolidated its role as a global innovator by introducing new patented filtration technologies, setting new industry standards. 2022 marked a new phase of growth, with the expansion of the production site, the acquisition of cobots for welding, and the implementation of an advanced ERP system to monitor production.
Today, under the guidance of Riccardo and Laura Bettella, the founder's children, Coynco continues to grow, developing new ranges of industrial vacuum cleaners with advanced filtration and safety technologies. With a vision that combines tradition and innovation, Coynco is synonymous with Italian quality, tailor-made solutions, and cutting-edge technologies, confirming its position as a trusted partner in the global manufacturing world.
