Clean Gas Deduster VJD
VJD series dedusters are high-performance individual extraction systems operating with negative pressure at an operating volume flow of 5,000 to 10,000 m³/h and compressed air filter cleaning. The fan is downstream from the filter and therefore located on the clean gas side. Thus fans with a high efficiency factor can be used in the dedusters, for extremely economical operation. The arrangement of the fan on the clean gas side significantly contributes to the reduction of fire and explosion hazards, since impurities cannot come into contact with the impeller or fan housing. Damage, not to mention flying sparks, are therefore excluded.
All dedusters come with a dry extinguishing line as standard equipment. Optionally they can also be equipped with an automatic extinguishing system consisting of a temperature sensor and hydraulic valve. VJF series dedusters are suitable for outdoor and indoor installation (the respective national regulations have to be observed for indoor installation).
Fields of application
The following materials can be extracted reliably with our dedusters:
- Wood dust and chips
- Paper (dust)
- Cardboard packaging (dust)
How the dust collectors work
The raw gas with the dust and if applicable material fractions is suctioned into the filter section of the deduster through a duct with negative pressure. Heavy particles fall directly into the drums in a pre-separation chamber. Lighter particles and dust are suctioned into the bag filters, where they accumulate on the filter surfaces.
The bag filters are cleaned at intervals using compressed air. Dust and particles are collected in the bags in the dust bins. Clean gas is discharged to the outside by the high-performance fan. After switching the deduster off, the drums can be rolled out of the deduster and the dust collection bags can be disposed of or emptied at the disposal location.
