Product details
Part AC70KAHHZB00 is the replacement spring for the bleeder valve fitted to Panasonic's commercial upright line. This small component manages how much suction the machine delivers: the valve itself bleeds a controlled amount of air into the main airflow, letting an operator back off suction for delicate fabrics without switching tools, and the spring holds that valve shut against normal running pressure.
When the spring loses tension or snaps outright, the valve can no longer hold its seal, and suction becomes inconsistent from pass to pass rather than cutting out completely, which makes it easy to mistake for a clogged filter or worn belt if nobody checks the valve itself. Swapping the spring on its own puts airflow control back where it belongs, without touching anything else in the assembly, making it one of the quicker fixes on these machines.
- Part: bleeder valve spring, part AC70KAHHZB00
- System: suction regulation / bleeder valve assembly
- Function: holds the bleeder valve closed against airflow pressure
- Tip: swap the spring by itself, no need to pull the rest of the valve assembly apart
Because the valve sits inside the body near the motor housing, replacing the spring usually means opening the same access panel used for a belt job, so it is a natural add-on repair rather than a separate teardown of its own. Panasonic commercial uprights have used variations of this bleeder valve design across several model years, so verify against your machine's part diagram before ordering rather than assuming fitment from the model name alone.
