SILOTOP®zero is a cylindrically-shaped lter for the de-dusting (venting) of pneumatically loaded silos.
The stainless steel casing contains vertically mounted POLYPLEAT® lter elements. The automatic com-
pressed air cleaning system is fully integrated in the cover.
Dust is separated from the air stream through the POLYPLEAT® lter elements and recovered inside the silo
by the integrated automatic compressed air cleaning system.
SILOTOP® zero has been designed to be integrated to other systems, part of an installation, in order to realize
a well determined application.
Important
The terms “equipment”, “lter” used in this manual refer to the same machine.
As components meant for installation in a plant, the dust collector - not fully provided with safety means
- have to be considered “partly completed machinery”. Therefore, they do not bear an EC marking.
It is forbidden to start the equipment unless the equipment/plant in which it is to be installed has been
declared compliant with the Directive 2006/42/EC and further modications.

The dirty air enters the lter body (1), where dust is separated by the lter elements (8).
The compressed air pulse-jet cleaning system (3+4+5) removes the dust collected by the lter elements; then,
the dust drops back inside the silo.
3.4 Permitted use
3.5 Improper use not permitted
The SILOTOP® zero venting lters have the function of separating dust particles conveyed by an air ow or
gas, using ltering elements made of non-woven polyester.
The dusty air ow crosses the lter, which stops the dust particles, allowing the air to ow over it.
The dust collected on the lter elements surface is periodically removed by the cleaning system that can be of
the compressed air jet type.
Every other use must be considered improper, therefore not permitted.
The equipment must not be used as an element for discharging overpressure inside closed volumes. One or
more safety valves must always be provided in the plant to keep the pressure level within the lter pressure
resistance limits.
The air ow handled by the dust collector must never exceed the value dened in the order phase.
Using the dust collector when the components (lter elements, cleaning system, fan, if present, etc.) are not in
perfect conditions can cause harm to persons and to the environment.
Do not operate the lter unless the plant or the equipment in which it was incorporated is declared compliant
to the requirements of relevant national and local provisions in force.
It is forbidden to use the dust collector in potentially inammable or explosive atmospheres (ATEX).
It is forbidden to use the lter for inammable (magnesium powder, etc.) or explosive products.
It is forbidden to use the lter for products which can cause bacteriological contamination.

3.6 Noise level
The noise level of the SILOTOP® zero lter does not exceed the limit of the 2003/10/CE and 2006/42/CE Di-
rectives.
The measured equivalent continuous average sound pressure level LAeq is 70.0 dB(A).
All readings were make using a precision sound level meter placed at 1 metre distance from the equipment
and at 1.6 metres from ground, with compressed air shots at 6 bar each 28 seconds.
Noise measurements of installed equipment may vary due to site conditions.
Danger - Warning
Depending on the installation site, the installer must adopt suitable systems (barriers, etc.), if neces-
sary, to maintain the noise levels within the legally permitted limits.
The SILOTOP®zero lters operate under the following conditions:
1) Maximum permitted temperatures of the air ow:
POSITIVE:
80° C continuous duty
100° C peak*
* Maximum 60 seconds to return within the continuous operation limits.
NEGATIVE:
