YSI Air Compressors for IQ SensorNet

PriceRequest Pricing



YSI Air Compressors provide pressurized air cleaning to sensors and are controlled by relay connections in IQ SensorNet systems. Available in one-, two-, and four-channel versions, the YSI Air Compressor can clean up to four sensors with a single compressor. These powerful compressors provide compressed air output at up to 85psi.

  • Overview

    Why use air cleaning?
    Sensors within wastewater and other challenging environments can foul quickly due to the accumulation of solids or biological growth. In some applications, manual cleaning may be required frequently to maintain accuracy. Automatic cleaning systems, such as air cleaning, can reduce cleaning requirements and extend the time between manual cleanings. YSI Air Compressors are a rugged and versatile solution for automated sensor maintenance.

    Cost Savings - Available in single, dual and four-channel variations to clean multiple probes simultaneously and lower installation costs. 

    Low Maintenance - The unit’s powerful compressor connected to the sensor’s cleaning head assembly keeps probes clean and lowers manual maintenance requirements.

    Compatible with IQ SensorNet's extensive suite of online controllers and sensors.
