Harmann IZOBOX R
Four-way radial channel fan with reduced sound insulation
A fan in a rectangular housing for mounting in a system of round ventilation ducts. The IZOBOX R enclosure is made of galvanized sheet steel, has connection stubs and a connected connection box.
The dynamically balanced B-type impeller is an integral part of the engine (so-called motor with a rotating casing).
The drive in the IZOBOX R model is implemented by a four-speed, single-phase, asynchronous 230V, 50Hz electric motor with integrated thermal protection. The motor with the rotor attached to the rotating stator was mounted on a hinged service cover – easy access for maintenance. The inlet to the fan was secured with a net.
Controlling the speed change can be done by means of gear switches (sold separately) or through a dedicated power connector for the exhaust fan installed in the FFHC supply air handling unit.
The IZOBOX R fans can be connected directly to the FFHC supply air handling units as exhaust fans.
Degree of protection: IPX4
Insulation class: B, model 200 – class F
