Maintenance¶

The SPS30 is designed to be maintenance-free due to its "sheath air" technology, which protects the optical components from fouling.

Automatic Fan Cleaning:¶

• The sensor features an internal cleaning routine that spins the fan to maximum speed for 10 seconds to blow out accumulated dust.
• Default Interval: Every 168 hours (1 week) of continuous operation.
• Power Cycles: If the sensor is turned off and on frequently, the internal timer resets to zero. In this case, you should manually trigger a cleaning cycle at least once a week.

Manual Cleaning: Manual cleaning is generally not required and should not involve opening the casing unless it has failed, as this can damage the internal HEPA filter or optical alignment.¶
