Filter Monitor
Audit Compressed Air Filters for Energy Savings up to 50%
ΔP Savings Potential!
Compressed air audits are recommended practices today due to the tremendous energy
savings generated by reducing system pressure drop in manufacturing facilities.
The Filter Monitor will allow you to control the exact amount of pressure drop you
incur from centralized and point-of-use compressed air filtration. Unlike traditional
mechanical gauges which give color indications when pressure drop has already reached
10-12 psig (0.7 to 0.8 bar), the Filter Monitor will prompt you to change out your
element when your ΔP is still in the 5 psig (0.3 bar) range by providing a
60 DAY NOTICE that pressure drop is beginning its upward spiral into the 10-12 psig
(0.7 to 0.8 bar) range. Timely warning and maintenance represents a ΔP savings
of over 50%. The 60 DAY NOTICE gives Maintenance ample time to order and install
a replacement filter element.
Microprocessor Monitoring of ΔP Performance
A state-of-the-art microprocessor, designed and developed by Hankison International,
is the core technology of the Filter Monitor. The microprocessor technology allows
the Filter Monitor to operate in 3 Monitoring Modes.
Time monitoring mode
Oil-free air for critical food processing applications often requires timed service
intervals to guarantee safe air quality. Just input the number of months until filter
change-out. The range is 1-15 months. The factory default setting is 12 months.
ΔP monitoring mode
Most point-of-use applications specify a minimum required operating pressure. This
mode allows you to input a maximum allowable ΔP across the filter. Just input
within the range of 0.1-15 psig (0.01-1.00 bar). The Filter Monitor is programmed
to ignore momentary ΔP spikes, avoiding nuisance alarms. The factory default
setting is 10 psig (0.7 bar).
Filter performance monitoring mode
Upon start-up or element replacement, a learning period of 146 hours familiarizes
the Filter Monitor with the installation. The first 24 hours are not measured as
the filter element is "wetted" and stabilizes. During the following 7 day period,
the Filter Monitor will measure instantaneous P over 1,800 times per hour to develop
a unique Application ΔP Profile. The Application ΔP Profile is then used to forecast
the optimal time for element replacement and trigger a warning 60 days before the
optimal element replacement moment. From then on, a countdown on remaining days
until element replacement will flash on the Filter Monitor LCD every six (6) seconds.
