We are a leading global supplier of chemically resistant fans, exhaust air purification systems and ventilation systems for corrosive and environmentally harmful exhaust air and gases, as well as apparatus and process equipment for chemically aggressive liquids.

Our attitude

COLASIT combines tradition with trend-setting technology. High product quality and the recycling economy of high-quality materials highlight our responsible handling of resources. With a high level of in-house production depth, we implement the required flexibility when processing customer-specific product adjustments. Together with our worldwide partners, we solve application-related problems when handling chemically-aggressive media and liquids.

Our vision

Colasit is part of Green-Tech. Sustainability with chemically-resistant plastics is our business. We want to seek new horizons in the plastic fans, exhaust air scrubbers, apparatus construction and pipeline construction sectors.

Humility is an attitude that enables agile business units to be led in a goal- and results-oriented manner. We maintain flat structures and want to achieve our aims according to ethical principles.


Our company culture promotes talent, ability, drive, as well as technical and personal qualifications for our employees through innovation, agile management, teamwork and individual training and further training. Recognition of individual performance and opportunities for training and further training expand the personal perspectives horizon.
