Kirby BPI Unit - G3/AV2
$12.99
Product details
This genuine OEM Kirby BPI unit (Part #640303) is the internal component that directs airflow for dust collection on the G3 and AV2 platforms. It fits a wide range of Kirby uprights, from the GEN 3 and ULTIMATE G through the SENTRIA, Sentria II, and AVALIR series.
Because the BPI unit routes air toward the bag, a cracked or worn unit leaks and disrupts the airflow path, which weakens suction and filtration. Fitting the correct replacement restores proper air management so the machine collects dust efficiently again.
- Fits: Kirby GEN 3, G4, G5, GSIX, ULTIMATE G, DIAMOND EDITION, SENTRIA, Sentria II, AVALIR, AVALIR 2, AVALIR PLATINUM
- Part: genuine OEM internal airflow unit
- Benefit: restores strong suction and efficient dust collection
- Tip: inspect the surrounding seals while the unit is accessible
Manufactured to factory specification, the unit installs as a direct replacement. Confirm your Kirby model before ordering so the BPI unit fits your machine's airflow path.
