About This Item
The Pentair Air Bleed Assembly (24800-0120) is the OEM replacement air relief component for Pentair System:2 and System 3 Modular D.E. filters, including the PLD and PLDE series filter systems.
⚠️ IMPORTANT: VERSION / DATE QUALIFIER
Compatibility with PLD Filter Systems (models 155331P, 155333P, PLD50) is confirmed for 2009 and beyond. If your filter was manufactured before 2009, verify the part number against your equipment's service manual before ordering.
The air bleed assembly releases trapped air from the filter tank during startup and after backwashing, allowing the system to prime correctly and maintain consistent operating pressure. A failed or missing air bleed assembly can result in air locks, erratic pressure gauge readings, and reduced filtration performance. This assembly is also included with the Key No. 9A Replacement Module for the System 3 Modular D.E. filter — if you are replacing that module, confirm whether this part is already included before ordering separately.

Pro Tip
If your filter is a System 3 Modular D.E. and you are also replacing the Key No. 9A module, check whether the air bleed assembly is already included in that module kit before adding this part to your order. When ordering for PLD series filters, confirm your filter's manufacture date — compatibility for models 155331P, 155333P, and PLD50 is documented for 2009 and later production. Match the part number on your existing assembly to 24800-0120 before ordering.
