Radial fans

FIMA radial blowers are characterised by their rugged design (heavy duty industrial version) and longevity. We offer customised solutions in pressure-resistant, gas-tight and corrosion-proof designs for most applications in the chemical and petrochemical industries. 

Thanks to their high safety and quality standards, our system solutions are frequently implemented along with environmentally hazardous substances or potentially explosive compounds.

Standards improve the safety of industrial processes, ensure quality, reduce costs and avoid waste. This is why FIMA Maschinenbau GmbH takes German, European and American standards as its benchmark.

Our machines satisfy high standards

The American Petroleum Industry (API) Standards in particular make high demands of the industry. FIMA builds and delivers machines that comply with these specific requirements. Our tailored portfolio of compressors and blowers complies with API 617, 9th edition (Chapter 1, 2 and 3), API 614, API 670, API 671, API 672, API 673 and DIN EN standards. We thus help you to improve your plant’s efficiency and profitability.
