NETZSCH SmartRemoval

The economical and innovative system for easy filter hose change


This new type of filter hose changing system combines the advantages of conventional Top- und Side Removal Systems in one product.

In the past the choice made by companies purchasing dust filter systems was in general limited by the type of plant they already had: Basically, if the height of the building made filter change possible a Top Removal System was chosen, as such systems always have a lower residual dust content compared to Side Removal Systems. However, if the building was too low, then a Side Removal System was always chosen, although these always meant longer stoppages for changing filter hoses and cleaning. This was seen as the lesser evil compared to the high costs required for modification work to the production facilities.

This dilemma inspired the design engineers at NETZSCH Trockenmahltechnik GmbH to look at the problem of filter hose changing from the customer´s point of view. The resulting worldwide innovationis a new type of filter hose changing system that combines the advantages of conventional Top- und Side Removal Systems in one product.

No tools, quick and easy

The main conceptual emphasis during the development of the SmartRemoval was first and foremost on enabling an intuitive filter hose change without tools, which could be carried out easily and rapidly. In practice stoppages necessary for changing the filter hoses constitute a major cost factor, which can even be decisive for the profitability of individual campaigns with frequent product change.

A further focus was on reducing the residual dust content down to that of a Top Removal System. In the end, the designers of the SmartRemoval were able to solve both tasks. The well thought out installation technology is constructed in such a way to exclude mounting errors and the mounting of the SmartRemoval is up to 80% quicker than that of previous Side Removal systems. In addition to this its residual dust content is so low that it is comparable to that of conventional Top Removal systems.

  • Mounting time up to 80 % shorter compared to side removal systems.
  • Easy mounting from the raw gas side without additional tools.
  • Proven Snap Ring technology guarantees the dust-tightness of the clean gas chamber.
  • The same residual dust contents as with top removal snap ring systems.
  • Mounting errors cannot occur.
  • No additional space in the building needed for dismounting the support cages as required for top removal systems.
  • Existing systems can be modified and retrofitted
