Intake Air Filter Replacement for Aeration Cabinets The Atlantic Water Gardens TPD compressor filter replaces the intake air filter on TPD-series pond aeration cabinet compressors. The intake filter prevents dust, insect debris, pollen, and fine airborne particles from entering the compressor diaphragm chamber, where they would accelerate wear on the diaphragm and valve surfaces. Replacing this filter every 6–12 months is the single most important maintenance task for extending compressor life. Small Part, Big Impact on Compressor Life The compressor intake filter is often overlooked during maintenance, yet it is the primary barrier between the diaphragm and the outdoor air quality around your pond. In Canadian outdoor conditions — pollen seasons, dusty summers, and damp autumn conditions — an unfiltered or clogged intake forces the compressor to work harder and draws contaminants directly into the diaphragm chamber. A plugged filter also reduces compressor output noticeably, leading pond owners to incorrectly suspect a diaphragm failure when the fix is simply a filter swap. Compatible Systems Atlantic TPD-series aeration cabinet compressors Function Intake air filter — removes dust and debris from incoming air Replacement Interval Every 6–12 months (more often in dusty or high-pollen environments) Installation Tool-free twist-off replacement How to Replace Disconnect power to the aeration cabinet. Locate the intake filter at the compressor air inlet. Twist or unclip the old filter and discard it. Install the new filter, ensuring the seal is tight. Restore power and confirm normal airflow output through all diffuser lines. Mark the filter with the installation date for tracking the replacement interval. Ideal for all Atlantic TPD-series cabinet aeration systems maintained year-round in Canadian outdoor conditions.
