Energy conservation is crucial today, especially in ventilation and air conditioning. Longwell has developed a complete product range of dual-inlet, direct-drive centrifugal blowers with efficient Brushless EC technology for these applications.
Our integrated motor electronics enable convenient, infinitely variable speed control of the EC fans. Up to three air flow levels can be programmed in “Constant Flow” mode, ensuring a constant air flow even if resistance changes, such as when filters become clogged.
Switching from a traditional fan with an asynchronous motor to our modern, energy-saving technology is seamless and requires no design modifications.
