Abstract
The specific beech wood dust resistance coefficient values were experimentally determined in the condition of pulse-jet filtration using a pilot-scale baghouse. The experiments were carried out for two variants of the filter medium. One of them had a PTFE (Polytetrafluoroethylene) membrane on the working surface. Three values of filtration velocity and seven levels of dust concentration at the filter inlet were used to determine the variability of the specific resistance coefficient of beech wood dust accumulated on the filter medium. The values of the specific beech wood dust resistance coefficient depend on filter medium finishing and filtration parameters: filtration velocity and dust concentration at the filter inlet. The high concentration of dust at the filter inlet and low filtration velocity should be used, especially in filters with surface finished media, for the reduction in pressure drop, which would affect in a significant reduction of energy consumption.

Extraction systems equipped with filtration dust collectors are the basic technical measures to reduce dust in woodworking plants
This resistance is influenced by many factors depending on the course of the air filtration process, such as filtration parameters, type of filter medium, dust properties and cleaning parameters of the filter bags
The values of the specific dust resistance coefficient K2 are higher for the non-woven filter fabric with the PTFE membrane
Summary
Extraction systems equipped with filtration dust collectors are the basic technical measures to reduce dust in woodworking plants. The pressure drop through the dust cake accumulated on the filtration surface depends on the filtration velocity wf (m·s−1), filter area dust load s (kg·m−2) and the specific dust cake resistance coefficient K2 (s−1) as in Equation (3):. It results from the fact that the smaller particles would form a denser cake on the surface of the filter medium, which causes a greater resistance to the air flow [11] For this reason, a number of research works have been done [2,8,12], which resulted in determining the dust resistance coefficient for various types of dusts commonly separated in industry. It will be possible to determine the conditions when the pressure drop was reduced, which can result in a significant reduction in energy consumption in the woodworking industry
