Helios Fans SVS 125 B

The Helios SVS 125 B is a slim centrifugal fan box with integrated sound insulation, engineered for the efficient ventilation of bathrooms, toilets, and similar spaces in residential, commercial, and light industrial environments.

Built from extended galvanised sheet steel, the housing is internally lined with over 50 mm of abrasion-resistant mineral fibreboard for superior acoustic performance. It features spigots on both the intake and exhaust sides, complete with twin-seal rubber gaskets for secure, airtight duct connections. A service-friendly swing-out design allows easy access to the motor and impeller for routine maintenance or cleaning.

The fan is equipped with a high-efficiency centrifugal impeller made from durable polymer, with backward curved blades and dynamic balancing for smooth, low-noise operation.

Powered by a fully enclosed motor with ball bearings, impregnated windings, and built-in thermal contacts, the SVS 125 B offers two-speed operation (395÷270 m³/​h), giving users the flexibility to adapt airflow to specific ventilation needs. This model delivers quiet, reliable performance in space-saving installations.
