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 work best when integrated with our other solutions. You can design a whole facility’s conveying system from the beginning to the hopper, bin, and silo. 

EMJET Silo Filters come in standard sizes and you can therefore use them with solutions from other manufacturers. However, by using filters with Kopar’s mechanical or pneumatic conveying and storage solutions, you can unleash their full potential.

Suitable usage cases for EMJET silo filters

  • Receiving bin or silo at the end of a pneumatic conveying line when transporting material
  • Filling of silos from tanker vehicles
  • Loading and dry material unloading

Typical conveying solutions of materials in which Kopar filtering is applied

  • Activated carbon, ammonium nitrate, ash, asphaltene, Ba(OH)2, bentonite, bottom ash
  • CaO, Ca(OH)2, CaCO3, cement, coke, concentrates, FeSO4, fly ash, fructose
  • Glass, Glauber salt, gunpowder, synthetic resin. kaoline
  • LD dust, lead oxide, lead slag, lignin, lime, MgO, MgCO3, milk powder, Na2(SO4), oil shale
  • Pigments, plastic granules, polyethene, polypropylene
  • Quartz, sand, slag, soap, soy, starch, stone dust, sugar, talc, WHB dust, zinc dust

Designed to last in the toughest 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 bags, depending on the filterable material, size distribution, other material characteristics, and application with process conditions like dew point. The silo filters can also be trace heated and insulated if your needs require that.

Flexible usage

The conveying media, primarily air, must be exhausted from the system, namely the receiving bin, with minimal dust emission. The conveying gas is directed out through bag or fabric 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 EMJET10 to EMJET127 as standard equipment. Furthermore, sizes of up to 1200 m2 have been engineered and manufactured. Material selection is practically unlimited, though carbon steel, stainless steel, and acid-proof steel are the most common ones.
