Reverse Jet Silo Venting Filter

SV-M2 reverse jet silo venting filter is the industry-proven silo cleaning solution. This dust collector is well-suited for handling powders or bulk materials in pneumatic conveying system for industries of construction, machinery, chemicals, food and pharmacy, etc. Our dust reduction system stands out from vibrant cleaning system in terms of efficiency and low maintenance.

Being fitted with modular intelligent control system, this reverse jet silo venting filter is allowed for automatic self-cleaning on the basis of regular interval or differential pressure. Round machine body is manufactured with mild steel or stainless steel. Flanged connection is also available. Moreover, the protection cover adopts light-weighted high polymer material for easy maintenance and ensured safety.

Furthermore, a total of 12 filer cartridges are employed for up to 99.9% filer efficiency. Normally, the filter surface is 20m2 and air volume is 1500m3/h. However, we are pleased to offer tailor-made service to fit your specific needs.

Simulation of working condition
The picture below implies the changes happened in the process that normal bulk materials pumping system fills the feeding chamber. The changes cover the aspects of air volume, left space of feeding chamber, real filter surface of vibrant filter and reverse jet silo venting filter.

First period
At the beginning of feeding, the air volume is about 800m3/h and the left space of feeding chamber is fairly large. The real filter surface of these two air filtration systems is sufficient for application needs.

Second period
The air volume of pumping system is up to 1000m3/h, thus the left space of feeding chamber is accordingly decreased. The real filter surface of reverse jet silo venting filter basically is of no change. However, vibrant cleaner is left with half of the valid filter surface.

Third period
This is the last feeding period, and the air volume reaches 1500m3/h, resulting in the minimal left space in feeding chamber. Vibrating-type cleaner now only has 10m2 filter surface which is insufficient for the large air volume. This increases the possibility of damage of filter cartridges and explosives.

On the other hand, however, our reverse pulse jet filter still remains the filter surface as beginning, thus being absolutely capable of delivering remarkable cleaning efficiency.
