The Helios ELS-GUBZR is a flush-mounted casing featuring a flat design and an integrated fire protection encasement with a K90 (18017) fire protection classification. It is intended for use with ELS fan units in installation shafts, plasterboard systems, walls, or ceilings requiring fire safety compliance.
The casing includes a metal discharge spigot and a maintenance-free airtight backdraught shutter made from stainless steel. The fire protection shutter is activated by the release of a fusible link, effectively preventing fire spread.
This model offers a spigot on the right side for connecting a second room ventilation system, allowing flexible installation options. The casing can be rotated 90° to the left or right to suit mounting preferences.
Electrical connection is simplified through a removable quick plug connector. A cardboard cover plate is included to protect the unit during installation. The casing measures 262 x 262 x 95 mm (W/H/D) and carries DIBt approval No. Z‑51.1 – 193.
