  If the red triangle flashes on the display and the fan sounds and vibrates on your Sundstrom Respiratory Product, it's likely due to clogged filters. Try changing the pre-filters and particle filters. Also, check the hose to ensure air flows freely and that it's in good condition. Finally, verify that the exhalation valves with membranes are fitted to your head top.

How to troubleshoot Sundstrom SR 500 fan unit that fails to start?

  If the fan unit of your Sundstrom Respiratory Product fails to start, first, recharge the battery. If that doesn't work, check for fan-battery contact problems by bending, adjusting, or cleaning the battery terminals and ensuring there are two terminals. Also, check the contact rivets on the fan. If the battery is faulty, replace it with a new one and measure the voltage, which should be 13 – 17 V. Inspect the charger for dirt on the contacts and consider replacing it. If none of these steps work, the fan motor/electronic fault may be the issue, and you should send the fan unit for repair.

Why Sundstrom SR 500 fan does not run smoothly?

  If the fan on your Sundstrom Respiratory Product isn't running smoothly, it might be due to a clogged filter, an incorrect filter combination, or the absence of filters. Check that there are filters in the fan unit and that they are of the same type, such as SR 532 OV/SD/CL/HC/HF + SR 510 P100/HE.
