Prices & Options
The Helios Fans RSD 225/900 is a high-quality silencer designed to minimize noise in ducted ventilation systems. Constructed with a durable galvanized sheet steel housing, it features an inner lining of premium mineral wool for exceptional sound absorption. A fleece lining on the airflow side further enhances durability by preventing abrasion and fiber release into the duct system.
The dimensions and mounting hole circle are precisely engineered to match standard fan diameters (R 20), with hole patterns compliant with DIN 24155 specifications. The RSD 225/900 offers very low flow resistance while effectively attenuating sound, making it an excellent choice for HVAC systems that demand quiet operation and reliable performance.
