The kit is supplied with one flexible hose, one attachment arm with funnel and one bench mount bracket ready for installation at the workplace. A powerful, maintenance-free turbine provides continuous fume extraction at a maximum air extraction rate of 230 m3/h. When setting the Constant Flow Control, the adjustable turbine speed avoids unnecessary waste of power and saves energy.

WellerFT offers the highest efficiency dust filters to remove large to very small particles

What are dust filter classes?

Filters are classified based on the size of the particle that they can keep from returning back into the environment. The smaller the particles are, the deeper they penetrate into the respiratory system. The smallest particles travel via alveoli into the bloodstream. The top graph shows filter classes and the size of the particles they can efficiently filter. Particles are measured in microns, which is one millionth of a meter.

Each filter class is assigned an efficiency rating based on the ability to filter MPPS (Most Penetrating Particle Size). HEPA filters have efficiencies of at least 99.95% at 0.3 microns. The most penetrating size is a function of the structure of the filter medium, the velocity of the airflow through the filter, and the physical and chemical nature of the particles.
