Because of all of these factors, the customer must monitor and document the system airflow readings
for a period of time. The information collected will help determine the most appropriate time to change
filters. This process will ensure that the system runs at maximum efficiency while minimizing filter
replacement costs.
The easy access system of the Streamer helps with faster filter replacement and reduced
maintenance.
Where to Start
Start by making copies of the attached log sheet. This log sheet should be filled out for each
Streamer you have in your system. Make a physical check to ensure that the smoke / particulate are
being removed through the intake spark baffles. This can be done by a simple visual check during
normal operation. There should be a reduced level of visible smoke when the unit is in operation.
During maintenance, examine the intake spark baffle at the back of the welding booth(s). These filters
should be washed when they become visibly dirty / contaminated. The differential pressure sensor
does measure across intake spark baffles; however, visual inspection is required.
Replacement filter cartridges and spark baffles of all types are available from your Clean Air America
sales representative.
How to Determine the Filter Change Interval
At this point, take note and document the pressure differential readings displayed on the controller. It
may be easier to raise the plastic flip lid cover to access the display.
The controller will allow the pressure differential to build to 3.0 in. H 2 O (inches of water column). This means the unit will automatically pulse the next time unit is stopped. This value may be different if the
options on the controller have been changed.
The controller will allow the pressure differential to build to 7.0 in. H 2 O. At this point it will automatically pulse while the unit is running until the pressure drops below 7.0 in. H 2 O. This value may be different if the options on the controller have been changed.
When the unit begins pulsing, it does not mean that the filters are no longer unusable. This pulsing is
simply the cleaning cycle which extends the filter life and reduces operating costs.
