Principles of pulse-jet filters used in the woodworking industry. The pulse-jet filters used to separate
wood dust and factors influencing their operation were described in this paper. The analysis of the possibility of
the use of pulse-jet filters for wood dust separation presented in this work was based on two basic quantitative
criteria. These are the separation efficiency and the pressure drop in the filtration process performed in a dust
collector. The influence of wood dust type, filtration velocity and air relative humidity the separation efficiency
and the pressure were described.
