1984: the beginning of a success story
In the 80s, Helios focuses even more on domestic ventilation and impresses with technically sophisticated solutions. However, none of them is as groundbreaking for the company's further development as the ELS mono tube ventilation system, which is launched on the market in 1984 and has been inseparably linked with the Helios name ever since.

1993 - now it's getting colorful (and even quieter)
The new generation of ELS draws attention to itself with a campaign featuring a pop art look and bright product colors. But the product itself is also impressive: ELS now has a completely closed front, is significantly quieter and comes onto the market with a clever filter change indicator. In 1998, an improved version with a long-lasting permanent filter and further optimized noise levels once again raised the bar.

2008 - ELS becomes the industry benchmark (once again)
When Helios 2008 launched its new generation of appliances in 2008, the market for mono tube ventilation systems was shaken up. Because ELS seems to effortlessly crack practically every best value in all disciplines. This does not go unnoticed for long and Helios wins a string of product awards at home and abroad. In 2017, ELS EC comes with ultra-modern and extremely economical EC motors.
