Simba Series Venting (SSV)

The Simba Series Venting (SSV) (Plug-On) unit is specifically engineered to handle the high dust loads associated with pneumatic conveying of a wide range of materials and products.

The unit is mounted on top of receiving silos or bins via rectangular upstand housing. This design ensures that the filter bags remain isolated from direct contact with the conveyed product, enhancing durability and performance.

Dust accumulation on the filter bags is automatically removed by an integrated reverse pulse cleaning system, with the collected dust efficiently returned to the process—ensuring continuous operation and minimal product loss.

 

 

FILTER UNIT SIZES

SSV units are available in a range of sizes from 7 m² to 60 m², providing flexible solutions to suit various application requirements.

FAN OPTIONS (SIMBA “E” SERIES)

Where integral fans are required, SSV units can be fitted with Simba’s “E” Series fans, available in sizes from 0.75 kW to 7.5 kW.

These fans are equipped with high-efficiency backward-curved impellers, designed to:

·       Maximize airflow efficiency

·       Reduce energy consumption

·       Ensure reliable, long-term performance

CONFIGURATION OPTIONS

The SSV range is available in multiple configurations to suit specific operational requirements:

Type B
Basic filter unit for positive pressure systems, typically installed indoors where there is no exposure to external elements.

Type H
Fitted with an exit header, allowing connection to a stand-alone fan or discharge ducting system.

Type W
Designed for overpressure venting systems, fitted with a weather cowl for outdoor use. No fan is included.

Type F
Supplied with an integral fan (Simba “E” Series), suitable for applications operating below atmospheric pressure.

Type F-AD
Includes all features of the Type F unit, with the addition of an acoustic diffuser (silencer) to minimize fan and motor noise.


PRINCIPLE OF OPERATION

Pneumatically Fed Silos and Bin Venting

Dust-laden air is pneumatically conveyed into the silo or bin, where a reduction in air velocity promotes natural particle separation through gravitational settling.

Fine particulate matter is captured on the outer surface of the high-performance filter media, forming a dust layer, while clean, filtered air passes through the media and is safely discharged to atmosphere.

To ensure consistent filtration efficiency and uninterrupted operation, the system incorporates an advanced reverse pulse jet cleaning mechanism. Controlled bursts of high-pressure compressed air are injected into the interior of each filter bag, momentarily reversing the airflow direction.

This rapid pulse causes the filter bags to expand and flex, effectively dislodging the accumulated dust layer (“dust cake”). The dislodged dust is then returned directly to the silo or bin, ensuring minimal product loss and continuous system performance.
