DH — High-efficiency HEPA filter
The DH filter is designed for the filtration of ultrafine particles. Used in medical, pharmaceutical and electronics applications and in research centres, it meets the most demanding standards in force, such as EN 1822.
It is usually fitted in the air handling unit, upstream of the M or JET terminal filters in our range. The pleating of the media is optimised — filtration area relative to face area — to obtain the best possible airflow to pressure drop ratio, which extends filter life.
