Restore your system to a fully functional condition with the VHT replacement air pump. The VHT air pump assembly replacement is designed for models 3600, 4500, and 5200. It includes The updated Check valve. The improved external check valve fixes the old sticking rattail-style valve. The new valve is less restrictive resulting in quieter performance and faster vacuum recovery.
If your system is older and the motor or bearing is in need of replacement, consider the air pump complete.
