Why is my Tennant S20 dusting excessively?
- M
  Melissa GomezAug 26, 2025
  Excessive dusting from your Tennant Blower can occur due to several reasons. The hopper door might be partially or completely closed, so make sure to open it. The vacuum fan could be off; if so, move the vacuum and filter shaker lever to the 'Vacuum fan on' position. Also, the hopper dust filter might be clogged; try shaking, cleaning, or replacing the dust filter. Check if the brush skirts and dust seals are worn, damaged, or out of adjustment, and replace or adjust them as needed. The cyclones might be dirty or clogged; clear any blockages. A damaged vacuum hose should be replaced. Additionally, ensure the Thermo Sentry wires are connected, and if the Thermo Sentry has tripped, allow it to cool.

  chernandezSep 9, 2025
  If your Tennant Blower is experiencing excessive dusting, start by checking if the hopper door is fully open. If it is, ensure the vacuum fan is on by moving the vacuum and filter shaker lever to the 'Vacuum fan on' position. A clogged hopper dust filter can also cause this issue, so try shaking, cleaning, or replacing it. Also check the Thermo Sentry wires are connected. If equipped, make sure the water tank is full, and if your model has a wet side brush, ensure the dust control switch is turned on and that the filter and nozzle are clean.
