Dust filters and sawdust silos

Nawara dust filters and sawdust silos for the woodworking industry: modular RUBIN, stationary TOPAZ, and biomass silos for storing collected material.

Here you will find dust filters and sawdust silos — these are components of the extraction system that separate dust and chips from the extracted air and store the collected material. For information on the entire system — local exhaust, ducting, engineering — see the extraction systems page.

Nawara dust filters. Elister is the official Nawara representative in Estonia. Two solutions are available, the difference being their expandability:

  • Nawara RUBIN – modular dust filter. Consists of sections that can be added as production grows. Ensures uninterrupted operation even when one section is being serviced. Suitable for the woodworking, metalworking and construction industries.
  • Nawara TOPAZ – stationary dust filter. A compact solution with fixed capacity for woodworking shops and smaller production facilities.

Sawdust and biomass silos. The filter separates dust and chips from the air, but this material has to go somewhere. The silo stores wood dust and chips and dispenses it evenly — either back into production or to the boiler house for heating. This way material does not accumulate in the work area and handling does not require constant manual labour.

The choice of filter depends on how much air the system moves and what type of dust is being separated — fine dust from sanding behaves differently from coarser chips from sawing. We will help determine the dimensions of the filter and silo together with the rest of the system.

Common questions about this product.

Frequently asked questions

What is the difference between a modular and a stationary dust filter?
The modular version (Nawara RUBIN) consists of sections — as production grows, additional sections can be added, and while one section is being serviced, the rest continues to operate. The stationary version (Nawara TOPAZ) is a compact solution with fixed capacity, suitable when the volume is known and space is limited.
What is a sawdust silo used for?
The filter separates dust and chips from the air, but this material has to be collected somewhere. The silo stores it and discharges it evenly — either back into production or to the boiler house for heating. Without a silo, material accumulates in the work area and must be handled manually on a constant basis.
How to choose the right filter size?
Determines the air volume the system moves (m³/h) and the type of dust. Fine dust from grinding requires a denser filter than coarser chips from sawing. The filter dimensions are established together with the fan and ductwork — a filter selected on its own may not suit the system.
Can filtered air be recirculated back into production?
Often yes — it keeps heated air inside the building and reduces heating costs. Whether it is permitted depends on the type of dust and the filtration efficiency; we review this separately for each solution.
