OPTIMA ONLY
OPTIMA pumps have a refillable air filter that should be periodically replaced. Simply remove air filter cover and replace the soiled filter with new material. |
BACK PRESSURE
Back pressure is the build up of pressure on the diaphragm due to resistance to air flow caused by restriction of air. This occurs when excess air is produced by the air pump, or when the air channels are inadvertently blocked. Back pressure resulting from clogged air stones or other air system blockages and restrictions will, over time, cause the diaphragm to expand and rupture.
An expanded diaphragm leads to a loss of air volume while the rupture results in total loss of air.
