Econometer/Economizer for Ultra-Filter DF 0035 - 11000 pages

for Ultra-Filter™ DF 0035-1100
Econometer: Basic differential pressure monitor indicating the need to change the filter element.
Economizer: Microprocessor monitoring and control indicating the most economical time
to change the filter element.

Donaldson Ultra-FilterTM DF filters
are ideal for filtration of compressed air and other
gases in a wide range of applications. The “total filter”
design concept behind these filters incorporates the
following characteristics:
• High performance • Ease of use
• High efficiency • Flexibility
• Compact size • Safety
Additional energy cost savings can be achieve with
the Ultra-Filter through the use of our Economizer
microprocessor-controlled differential pressure gauge.
While continuously monitoring differential pressure,
the integrated microprocessor calculates the cost of
element change-out relative increasing energy costs
from rising pressure drop, and signals the most
economic point at which to replace the filter element.

Savings by using the Economizer
Operating signals can be remotely-monitored and,
alternatively, the differential pressure signal can be
transmitted via a standard analog interface (4-20 mA).
