The AirShield® soiling prevention system increases the long term accuracy of sensor readings and reduces cleaning frequency requirements by providing a constant air barrier to prevent dust and dirt from settling.
A high performance air blower drives double filtered compressed air to an injector head that creates an air barrier in front of the sensor. The system can be operated with AC power or solar power.
