The Systemair DVN 450D4 IE3 Centrifugal Roof Fan delivers high-performance ventilation with reliable operation for both industrial and coastal applications. Designed with a seawater-resistant aluminum casing and backward-curved impeller, this fan ensures durability even in harsh environments. Featuring a standard motor located outside the air stream, effective vibration dampers, and optional 50 mm mineral wool insulation (DVNI version) for lower sound levels, it operates continuously at temperatures up to 120°C. The motor is speed-controllable via transformer for single-phase models and D/Y connection for three-phase models, with integral thermal contacts for motor protection. Its vertical discharge design, combined with powder-coated galvanised steel base frame and integrated guard, makes this fan ideal for safe, efficient, and quiet roof ventilation.
