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, ...

Until now, ventilation boxes were intended for purely professional use, more specifically in the health sector. Our main customers were laboratories, hospitals and clinics, and also some companies in the food sector. They installed these devices in operating theatres or places where the air quality must be as sterile as possible. But the current ...

Indoors, air quality is determined by various factors, both organic and inorganic: some building materials, the use of cleaning products, the combustion of energy-consuming gases, human life itself and polluted air coming in from outside are the causes of unhealthy indoor air. The best way to combat this poor indoor air quality is to have ...

Rosenberg has supplied an Airbox air handling unit with an airflow capacity of 21,000 m³/h for installation in the industrial kitchen area of a major catering service provider in Germany. This project exemplifies the integration of advanced ventilation technology in demanding environments such as large-scale professional kitchens. The unit ...

When air sterility is compulsory in certain activities, one of the solutions with which these requirements are obtained are the Dif-Vent and Dif-Pur diffusers, designed by the innovation department of Airtècnics. They are fans with diffusers provided with HEPA and ULPA absolute filtration stages. These products of the ventilation ...

Rosenberg Ventilatoren takes the efficient design of its PlugFan centrifugal fans one step further, increasing their performance by 7–8%. This improvement is due to the implementation of a surrounding housing that enhances efficiency and reduces noise levels by up to 4 dB.The optimization of the fan structure ensures a much more uniform ...
