Classification & Storage / EMJET silo filters
Minimizing the emissions with EMJET filters
Kopar silo filters are designed to complement especially the pneumatic conveying solutions. Proper filtration is essential when filling and unloading storage silos.
Filtration is often associated with conveying or handling dusty, powdery material when dust emissions must be very low. Pneumatic conveying is a good example of that.
Designed to last, our heavy-duty silo filters can handle the varying air pressures when transporting the material into the silo.
We host a family of bag filters under its brand name EMJET. EMJET silo filters are a result of years of engineering and R&D work. They perform best when integrated with our other solutions. However EMJET Silo Filters come in standard sizes and can therefore be used with solutions from other manufacturers as well.
Full advantages of the EMJET filters realise in using them together with Kopar mechnical and pneumatic conveying as well as storage solutions.
Easy servicing and maintenance is one of our key drivers and this has been considered in EMJET silo filters as well.

Designed to last in the harshest conditions
Adaptable characteristics
Proper filtration is essential when filling and unloading storage silos.
Our EMJET silo filter solution uses a bag hose filter with a pulsed air cleaning system, which is automated and operates typically based on a pressure difference over the filter bags. Filters are designed so that the bags are easily replaceable.
There are several material alternatives for the filter bags, depending on the filterable material, its size distribution and other characteristics. Process conditions like dew point pay a role in selecting the most suitable filter bag material.
The silo filters can also be trace-heated and insulated if required.
Flexible usage
The conveying media, primarily air, must be exhausted from the system, namely from and through the receiving bin, with minimal dust emission. The conveying gas is directed out through bag filters, resulting in the required dust emission rate, typically < 5 mg/Nm3.
Filtering can be applied with targeted suction positions, where several suction points can be directed into one filter.
Filters can also be equipped with a fan whenever that is needed.
Large filtering surface range
EMJET filters are always accompanied by a number representing the filtering surface area in square meters m2. Our filtering family comes in various sizes ranging from EMJET9 to EMJET127 as standard sizes. Furthermore, sizes of up to 1200 m2 are available as tailor-made. Material selection is practically unlimited, though carbon steel, stainless steel, and acid-proof steel are the most common ones.
