DUAL-Silencer for FM fans

DUAL-silencer for enclosure of FM fan motor and the top of the fan case

The DUAL-silencer encloses the fan motor and the top of the fan case. It may be fitted to any FM unit and take the place of a conventional in-line silencer, with the added benefit of reducing breakout noise from the fan.
The DUAL-silencer is available in three sizes, to fit FM600 series, FM800 series fan and the FM1000 fan.

Description
The DUAL-silencer is made of 2mm galvanized steel.
The grille may be fitted with a rain cover or replaced by a flanged outlet. These items are interchangeable and are clipped into place on the silencer.
