4. Element Cleaning - Inlet Filtration
Solberg elements should be cleaned or replaced, once the pressure drop
reaches 15 to 20-inches water column (380 - 500mm WC) above the initial
pressure drop of the installation.
The decision to clean the element rather than replace it is left to the discretion of
the operator. Any damage which results from by-pass or additional pressure drop
created by element cleaning is the sole responsibility of the operator.
*WARNING*
The overall performance of a filter element
is altered once cleaned.
The initial pressure drop after cleaning will
be greater than the original, clean pressure
drop of the element.
After each subsequent cleaning, the initial
pressure drop will continue to increase.
Under all circumstances, the initial
pressure drop of the element needs to be
maintained at less than 20-inches water
column (500mm WC).
Cleaned elements that exceed 20-inches
water column (500mm WC) at start-up
should be replaced with new elements.
With many types of equipment, the maximum pressure drop allowed will be
dictated by the ability of the equipment to perform to its rated capacity. Under all
circumstances, the operator
should avoid exceeding the manufacturer’s
recommended maximum pressure drop for their specific equipment.
A. Polyester Element: The polyester element may be washed in warm
soapy water, vacuumed, gently blown out or replaced. The element
should be dry before reinstallation. The element should be replaced after a
maximum of three cleanings.
B. Paper Element: The paper element may be lightly blown with low
pressure air. It is disposable and in most cases should be replaced with a
new element.
