Delta P Plus Control 

Description

The Delta P Plus Controller monitors the differential 

pressure between the clean and dirty air plenums, 

providing a visual display of the filter condition. When 

combined with a pulse timer, it controls the pressure 

drop by turning the cleaning mechanism on and Off at 

the chosen limits. There are three (3) set points: High 

Pressure On, Low pressure Off, and Alarm. The first two, 

High Pressure On and Low Pressure Off, control the 

filter cleaning system. The third, Alarm, provides a relay 

output to activate an external alarm supplied by others.
The user can program the Delta P Plus Controller to 

pulse while the collector is running, to maintain a 

relatively constant pressure drop across the filters, pulse 

only after the collector is shut down (after-shift cleaning), 

or a combination of both, cleaning while running as well 

as end of the shift.

Operation

Normal

The Delta P Plus Controller monitors the pressure on 

both sides of the tubesheet while the unit is running. 

As air flows through the filters, the resistance of the 

media and collected dust creates a pressure difference 

or "drop" between the dirty and clean air plenums. The 

Delta P Plus Controller measures the pressure drop and 

provides a visual display in inches water gauge or metric 
(SI) units of daPa.
Filter Cleaning
The Delta P Plus Controller offers three filter cleaning 
options.
1.  Differential Pressure Cleaning (DFF) - When the 

pressure drop across the filters reaches the 

Controller's High Pressure On setpoint, the Controller 

closes an output relay allowing a sequential timer 

to trigger the cleaning valves. When the Controller 

senses that the pressure drop has decreased to 

the Low Pressure Off setpoint, the relay opens and 

the cleaning cycle stops. This sequence continues 

as long as the collector is in use, maintaining the 

pressure drop within a narrow range. 

2.  Downtime Cleaning (DTC) - The Delta P Plus 

Controller monitors the collection system.  When 

the pressure drop exceeds the Low Pressure Off set 

point and then approaches zero again, the Delta P 

Plus Controller runs a delay timer to allow the blower 

to come to a stop and then engages the cleaning 

mechanism for a preselected time.

3.  Combined Differential and Downtime Cleaning 

(ALL) - The Delta P Plus Controller combines the two 

functions described above; maintaining the pressure 

drop in a narrow band and downtime cleaning 

the filters when the collector is shut down. The 

downtime cleaning function can be toggled On or Off 

from the keyboard. 

Alarm

The Alarm setpoint is set to a higher setting than  the 

High Pressure On used to start the filter cleaning cycle. 

It indicates situations when the cleaning system cannot 

reduce the pressure drop due to cleaning system failure, 

lack of compressed air, or the end of the filter's useful 

life. There is a time delay prior to setting the Alarm to 

prevent nuisance trips. The Delta P Plus Controller also 

provides an input connection for a remote Alarm reset. 
For complete information, see the most current version of 

the Delta P Plus Installation, Operation, and Maintenance 
manual.
