Air Curtains Specialist - Industrial Ventilation
Our laminar flow absolute filtration units Dif-Vent, intended to avoid the external pollution and increase the class of a certain area as it could be a clean room, have been redesigned and now incorporate fans with EC motors.
These types of motors are up to 70% more efficient and allow speed regulation by 0-10V signal.
With these improvements, Dif-Vent filtration units comply with the requirements of the Energy Efficiency European Directive, Erp 2015.


How does an EC motor work? The EC (electronically commutated) motor is a synchronous motor powered by an inverter with permanent magnets in an external rotor design. The stator is driven by electronic switches controlled by a microcontroller. The motor needs to be supplied with AC voltage and a DC voltage signal to operate.The mains voltage, ...

Maxwell air curtains, which until now have been served with AC fans, can now be manufactured with energy-saving EC fans. This makes it a highly efficient industrial air curtain with increased flow and power. EC motors are a synchronous motor powered by an inverter with permanent magnets in an external rotor design. The AC mains voltage is ...

The best way to extend the life of a building's HVAC system is to upgrade it. To do this, it is essential to replace the old, inefficient belt-driven fans with an ECFanGrids. These are more efficient and are designed to be fail-safe. The advantages of carrying out a retrofit project with ECFanGrids are numerous, which is why a technology company ...
