The main causes of an ineffective air curtain are that the air curtain is not adapted to the special conditions required for each installation, but it is also a problem when the installation is not carried out according to the specifications of the air curtain in question.

Depending on the model, the curtain can be recessed, hanging or fixed to the wall or floor, vertical. The curtain must have enough space around the motors so that the air can flow ...

HEPA filters are a system for retaining volatile particles present in the air, generally made of fibreglass.

They were developed in 1950 by the Cambridge Filter Company and were exclusively intended for the military industry to combat pollutants from atomic bomb manufacture. Today, HEPA filters are adapted to all fields: food industry, electronics, pharmaceuticals, ...

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 panorama, the awareness of the importance of quality indoor air and avoiding the spread of diseases in crowded places, has led us at Airtècnics to turn the screw and launch two state-of-the-art purifier boxes, to which other models ...

Air is an essential element in human survival, and the fact that this air is pure is an exponential benefit to that survival. For the best quality of life, the air that we breath must be the purest as possible because air nourishes with oxygen the lungs, the blood and, consequently, the rest of the organs. Surprisingly, indoor air is five to ten times worse than outdoor air, according to several WHO studies, even in urban areas. Among the pollutants found inside homes, offices, restaurants and leisure facilities we can number: carbon monoxide, volatile organic compounds, sulphur ...
