Harmann IZOBOX
The fan in the housing with reduced sound insulation
Radial duct fan in a rectangular housing with sound insulation. The casing is made of galvanized sheet steel with a hinged service cover (fixed with quick clamping clamps), connecting sockets and a junction box. IZOBOX is a model with a layer of sound insulation reduced by approx. 10% while maintaining the properties of full insulation. The sound absorbing material is a 35 mm layer of mineral wool meeting fire protection requirements for class A1 – non-flammable.
The dynamically balanced impeller type F is an integral part of the engine (so-called motor with a rotating casing).
The drive in the IZOBOX model is realized by a single-phase asynchronous 230V, 50Hz electric motor with integrated thermal protection. The motors are adapted to voltage speed control in the range from 80 to 230V.
Due to the acoustic insulation of reduced thickness, IZOBOX is especially recommended for installation in limited space installations (eg suspended ceilings) in libraries, conference rooms, schools, hospitals, etc.
