What does modular design mean?
Which are the advantages of modular design for filter and extraction systems?

At TBH, filter and extraction units with a modular design have one unit for the engine, one for the lid and at least one for the filter. Several filter units can be installed into a system one by one, or be supplemented with other units such as spark extinguishers. Depending on pollutants and particle concentration in the air, the filters complement each other in order to be geared to fitting the required processes even better.
Another advantage is, when changing the filter, only the respective saturated filter has to be replaced without completely dismantling the system. Visually, the systems look similar, but their units are differently composed, which make them suitable for various processes. Each system is therefore versatile. The units are manufactured individually and can be easily assembled / integrated on demand into an ordered system as desired. This enables a flexible and fast manufacturing process and thus shorter production cycles.
