The Rhino Ultra Silenced Fan is a powerful and exceptionally quiet EC extractor fan for grow rooms and other controlled ventilation systems. The series combines high airflow with effective sound insulation and is available in five sizes from 150 to 355 mm with a maximum airflow of 530 to 4,357 m³/h.

The cylindrical housing is made of reinforced steel and lined with noise-reducing acoustic foam. According to the manufacturer, this reduces operating noise by more than 50% – even at maximum power. This makes the Ultra Silenced Fan particularly interesting for installations where powerful extraction needs to operate as quietly as possible.

Modern EC technology allows for stepless control of fan performance from 0 to 100%, without annoying humming or buzzing. Additionally, the fan features a soft-start function: after switching on, the motor slowly and controllably accelerates to the set performance level. This protects the motor and electronics and reduces sudden load peaks.

Integrated hanging eyelets facilitate installation. The fans can also be combined with suitable controllers. For an optimally coordinated exhaust system, Rhino recommends combining it with a suitably sized Rhino Pro activated carbon filter.

With power levels from 40 to 550 watts, the Ultra Silenced series covers both smaller exhaust systems and very powerful installations.
