Innovative Engineering

The SILENT MV has been designed with state of the art technology to achieve results to satisfy the most demanding specifier. The low profile and compact design of the helicocentrifugal fans enable them to be installed where space is restricted, such as false ceilings.

Unique Design

The unique perforated design of the casing directs sound waves into the high density sound absorbent material to prevent air leakage and minimise noise.

Rotating Connection Box

The connection box can be rotated 360° to enable the power cable to be easily connected.

Rubber Seals

Bi-material inlet and outlet incorporating a rubber seal to facilitate installation and absorb vibrations.

How does it work?

Sound waves produced inside the SILENT MV are directed through the perforated inner cover and absorbed by the layer of sound absorbent material.

Ease of Maintenance

The central body of the SILENT MV can be easily dismantled from the connections to enable rapid maintenance, without the need to interfere with the ducting.

Support Bracket

Suitable for wall or ceiling mounting, fixing brackets to the motor body are included.
