HEPA filters are a system for retaining volatile particles present in the air, generally made of fibreglass. These randomly arranged fibres are extremely fine and form a mesh-like lattice that retains contaminating compounds. HEPA stands for "High Efficiency Particle Arrester" and is also known as absolute filters. They were developed in 1950 by ...

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, ...

Given the importance of environmental protection and the need to save energy, one of the many demands in ventilation projects is the replacement of the large belt-driven fans. The air handling unit is completed with new EC Fan Grid fans, which form a grid of smaller fans, but with the same flow rate.   The main advantage of having EC Fan ...

Researchers by the Polytechnic University of Madrid (UPM) have performed a study which reveals that the use of high efficiency air curtains results in significant improvements in efficiency and energy savings.The study, published in the journal Energy and Buildings, analyzes in depth the energy savings and hygrothermal conditions improvement ...
