Cylindrical type filtration mesh or filtration screen provide biggest filtration area in a given space. In general, there are 2 types of applications:

  • Rocket Filter
  • Candle Filter or cartridge filter

Rocket filter is not uncommon in blown film lines due to its big filtration area and in longer processing period, back pressure built up is relatively slow. Further, this feature also enabled a stable process of high fillers materials. Beside this, rocket filter is also common in some extrusion laminator equipment. Normally, this kind of cylindrical filtration mesh is smaller than candle filter.
Meanwhile, candle filter or cartridge filter is designed for high capacity and low change over rate. One product change in 2 to 3 weeks is not uncommon. With a combination of 4, 8, 9 or more cylindrical filtration elements in a single housing makes candle filter a perfect component to ensure stable, smooth and long processing period. Normally, this kind of filtration mesh is bigger than rocket filter.

The advantages of cylindrical filtration mesh or screen over wrapping method are:

  • Avoid technical error
  • A perfect welding avoid leakage
