  • > Powerful: ultraSilence® ELS truly generates pressure. 260 Pa at 60 m3/h, in fact. This is not only record-breaking, it also allows the smallest pipe cross-sections for the main line and thereby increases the possible living space. Quiet: With so much power, it is quite astonishing that ultraSilence® ELS is so quiet. 35 dB(A) at V· = 60 m3/h* is on the threshold of audibility and a value that nobody will beat. *(LPA at AL = 10 m2)
  • > Attractive: Best design at any price: ultraSilence® ELS is unique and has received globally recognised awards.
  • > Compact: The special achievement of a product sometimes lies in offering less: for example, with regard to the dimensions. In this respect, ultraSilence® ELS also holds the record with an installation depth of just 89 mm.

  • > Unique: The impeller developed by Helios generates a lot of pressure almost inaudibly.
  • > Barrierfree and fully Automatic: the ELS types operate with motion sensors or automatic humidity controls
    All ELS types are equipped with a permanent filter, which can be easily cleaned in the dishwasher.
    ELS is optimally protected against humidity: Installation in wet room zone 1 according to DIN VDE 0100-701 is possible without difficulty.
    The ELS ultrasilence can be connected to multiple areas as well as the WC
  • > Made in Germany: There is no substitute for quality and innovative strength. The Helios brand stands for both like no other. Thus, our mono tube ventilation systems, from the motor and control technology through to the impeller, are completely developed and produced in Germany. You can count on this.

The flush-mounted casing ELS-GU is not only delightfully compact, but also almost infinitely flexible in application. Whether it is used for single room and two room ventila- tion or WC connection via the flush pipe – ELS-GU fits optimally in all situations. Installation is possible in walls, shafts, plas- terboards or ceilings, whereby the discharge spigots can be optionally positioned to the back or top. Furthermore, the casing can be rotated by 90° to the left or right. Simple and without tools. There is just one casing type for each type of installation and all ventilation require-ments, which is not only practical on the construction site, but also extremely economical for storage.

1 Single room ventilation Intake via front facade.

2 Two room ventilation Two room ventilation with discharge to top or back.

3 WC connection WC seat connection via flush pipe, discharge to top or back. The flush-mounted casings from ultraSilence ® ELS are just as smart. ELS-GAP and ELS-GAPB with the fire protection damper can be mounted by turning the discharge spigots by 360°, so that the air outlet can be positioned to the top left or right and bottom left or right.
