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.


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 ...

There are certain sectors where dust and other pollutants are detrimental to production, and ventilation systems with filter stages are the perfect ally to prevent particles and residues of volatile compounds in the air. In the electronics industry, which is growing at a very fast pace due to the technical progress in society, in companies with ...

With the Ecodesign Directive 2009/125/EC (ErP Directive) the European Union has defined the requirements to the environmentally configuration of energy using products. This directive is part of the 20-20-20 target, according to which energy use shall be reduced by 20% and the share of renewable energies shall be increased by 20% until 2020. It ...

We show an EC FanGrid retrofit project that was carried out by our partner Rosenberg France with the installers MCI SAS. The project involved the modernization of three air handling units moving more than 50,000 m3/h in a large house in the province of Champagne, France. In this AHU retrofit project, the transmission fan were ...

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, ...

Efficient ventilation management in buildings is essential to ensure a healthy and comfortable indoor environment and to optimize energy consumption. EC motors have become a recommended choice for air curtains because of their efficiency and controllability. When integrated into building management systems using 0-10 V signals, monitoring and ...

Today we present a project of our partners from Rosenberg Germany, who have succeeded in installing insect-proof air curtains at the industrial entrances of an internationally operating tyre factory. In this project, two air curtains have been installed to cover the entire access to the logistics area. The Fly KL air curtain is ...
