MP Filtri DEH Series, Operator'S Manual

Page: 5 / 30

PRODUCT OVERVIEW
Product Presentation
Filter elements are efficient only if their dirt holding capacity is fully exploited. This is achieved by using filter housings equipped
with DEH Series clogging indicators.
These devices trip when the filter elements become blocked which causes an increase in the pressure drop across the filter.
The indicator is set to alarm before the element becomes fully clogged. This indicator will reduce the frequency of replacing filter
elements as well as maximising the performance of each filter.

Area of Application
Hazardous Area Indicators can only be used in the appropriate zone classification.
Ex d indicators should only be used in zones 1 and 2 - zones in which potentially explosive atmospheres created by
gases, vapours or mists are unlikely to occur in normal operation. In the event of an occurence, the situation will persist
for only a short period.
Ex ia indicators can be used in zones 0, 1 and 2. These are suitable in an area where explosive atmospheres are
continually present. For more information please see section 6 - Certification.
