This compact, high-output aerator pump is known for reliability and durability. The sealed, waterproof motor and impact-resistant housing make it ideal for harsh marine environments. The internal cartridge is easily replaceable and budget-friendly—perfect for long-term use.

Note: To connect a hose to the discharge port, you’ll need an adapter (sold separately).
