Tornado Tempest PTFE Flat-Pleated Filter K69074610

This is the main filter for the Tornado Tempest. Tacony sells it as a PTFE filter for the Tempest wide-area carpet sweeper, and the parts book describes it as a flat-pleated filter. It is the part that decides what the machine puts back into the room, and it is the single most important consumable on the sweeper.

What the PTFE Flat-Pleated Filter Does

PTFE-coated media matters here because the Tempest cleans its filter mechanically rather than by replacing it constantly. The coating gives the dust cake a surface it will release from, so when the shaker bar knocks the filter, the load actually falls off into the hopper instead of staying embedded in the pleats. An uncoated substitute will blind off far faster and no amount of shaking will recover it.

Where It Sits on the Machine

It sits inside the filter housing on the Tempest filter and blower diagram, sealed top and bottom by its own gaskets and swept by the filter cleaning bar.

When to Replace It

Replace the filter when airflow no longer recovers after running the shaker, when the pleats are visibly damaged or holed, or when the media has gone hard and grey through the full depth of the pleat. Any hole at all is a replacement — a filter with a tear is putting everything it catches straight back into the room, and it will also load the vacuum motor with dust.

Fitting Notes

Check both gaskets while the filter is out and replace either one that has hardened or taken a set, because a filter that is not sealed at its edges is simply bypassed. Seat the new filter squarely in the housing and confirm the cleaning bar sweeps its full face before closing up.

Frequently Asked Questions

How often does the filter need replacing?

There is no fixed interval — it depends on hours and on how dirty the carpet is. The practical test is recovery: run the shaker and see whether airflow comes back. Once it does not, or once the media has gone hard through the full pleat depth, the filter is finished. Any hole or tear is an immediate replacement regardless of age.

What is the difference between this and the pre-filter?

The pre-filter, part number K57452800, takes the coarse load first and protects this one. K69074610 is the main PTFE flat-pleated filter that does the fine filtration. Both are fitted, they are different parts, and running without the pre-filter will shorten the life of this one considerably.
