13.0 SOUNDPROOF CABIN
In line with current noise regulations, it has become an essential element in most work environments.
PG has carried out noise surveys to significantly improve this product.
It is constructed using panels of galvanised metal sheets, which can be dismantled. Each soundproofing
panel contains a layer of polyester noise-absorbing material, which is self-extinguishing, and a waterproof
film.
The various panels fit together with self-aligning pivots and they are fixed in position using the instant-opening
metal clips.
The cabins for large units (DN-200/DN-250/DN-300) are supplied with a side door. One panel of the cabin
is supplied ready for the optional installation of the pressure gauge, vacuum gauge and/or thermometer. It also
incorporates a plate to enable access to the electric cabling of the motor inside the cabin.
All of the cabins incorporate a compact electrical fan to renew the air inside.
The cabin and the unit are designed as one compact unit, which can be transported as such, thereby easing
transportation and later assembly.
