Helios Fans ELS-GU

The Helios ELS-GU is a flush-mounted casing designed for easy installation of ELS fan units within installation shafts, plasterboard systems, walls, or ceilings. This universal casing, made of flame-retardant polymer (class B2) in white, ensures safe and flexible mounting with embedded turn-locked slots for brackets and includes a cardboard cover plate.

Discharge spigot (DN 80 mm) is positioned to the top by default but can be repositioned to the left, right, or back to fit various installation needs. The built-in airtight backdraught shutter is maintenance-free, providing reliable airflow control.

Electrical connection is convenient via a removable quick plug connector. The casing also offers connectivity for second room ventilation or toilet pan rinsing via lateral rinsing tubes (DN 50÷40÷30 mm) on the left, right, or below.

When combined with the ELS‑D fire damper installed in the main duct, the system meets relevant fire protection regulations. Compact dimensions of 230 x 230 x 89 mm (W/H/D) and DIBt approval no. Z‑51.1 – 193 confirm its suitability for high-standard ventilation installations.
