DE20 Plus System Overview

EC Fan Technology

The Electronically Commutated (EC) fans used InovaAir Air Purifiers consist of a brushless DC motor with on-board electronics used to drive and control a fan rotor; compared to traditional AC induction motor technology. EC fans are powered by 240 Volt AC electricity supply, which is converted to DC power by the motor’s electronics. EC motors can be up to 30% more efficient than Induction motors, largely because the secondary magnetic field comes from permanent magnets rather than copper windings.

InovaSmartTM Digital Controller

DE20 Precise digital controllerDesigned for intuitive operation, the digital interface on the AirClean DE20 system gives you precise control of the fan speed. The digital controller also keeps track of filter life by continuously monitoring system usage based on hours of use and speed of the fan during operation.
