Integrated HEPA terminal filters with low pressure drop

The DUG-MAB LPD and DUG-DAB LPD low pressure drop terminal filters are certified as H14 efficiency according to EN1822. Due to their lower pressure drops compared to standard models, they consume less energy for the duration of their service life.
They are ideal for use in sterile environments with laminar vertical airflow and the strictest cleanliness requirements (ISO14644-1 classes 9 to 1); being extremely practical, they have revolutionised installations in cleanrooms in even the most demanding of industry settings: pharmaceutical, micro-electronics and electronics, food, aeronautical and chemical sectors.
