Our Flexible Build-Up Fans for Tailored Dust Removal Solutions

08 October, 2024

Apart from the mounting fans, we also offer our build-up fans, specifically designed for dust removal technology.


This fan design is particularly useful for direct installation in a vacuum filter system, where it replaces the filter cover. Of course, the plate dimensions can be customized to meet customer specifications, and as a contract and custom manufacturer, we follow customer requirements. 👍

It is also beneficial to have an integrated intake nozzle suitable for heavy-duty air operation.

In these fans for the same customer, high-performance impellers with backward-curved blades are used, running in VFD mode. At the customer's request, they feature a ring pressure sensor integrated into the intake nozzle and an inspection opening. The intake nozzle is additionally equipped with a protective grid. Our customers have different specifications depending on the system, and we are happy to implement them. 👏

The discharge side is usually equipped with a standardized flange frame and blows horizontally. 🌬️ The shown fan with straight discharge achieves a flow rate of 4,500 m³/h and a pressure of 4,000 Pa, powered by a 7.5 kW motor driving a 500 mm impeller. 💪

However, it is possible to connect an elbow directly, so the discharge occurs upwards. 💡 In the two identical fans with curved discharge, the 450 mm impeller and a 4 kW motor achieve a flow rate of 2,500 m³/h and a pressure of 3,000 Pa. 👍

Flexibility and customer value, proudly based in the Ore Mountains! ☺️
