The Helios ELS-GAP is a surface-mounted casing designed for easy installation of ELS fan units in any wall or ceiling position. This flat design housing allows flexible mounting, including in room corners, with a compact size of 250 x 250 x 130 mm (W/H/D).
Equipped with a discharge spigot (DN 80 mm) featuring a maintenance-free, airtight back draught shutter, the spigot is also rotatable by 90° to accommodate various mounting orientations. The casing is made from a flame-retardant polymer (class B2) in white, ensuring safe operation. Electrical connection is simplified with a removable quick plug connector for user convenience.
When used together with the fire damper ELS‑D installed in the main duct line, the ELS-GAP meets all relevant fire protection regulations. The casing is approved under DIBt certificate No. Z‑51.1 – 193, making it a reliable choice for safe and versatile ventilation system installation.
