In addition, the system can operate from 5PSI to 60PSI, so is equally compatible with both high pressure/low volume blowers or low pressure/high volume compressors. The vibrator housings have greater open areas, giving increased airflow and higher levels of vibration to prevent the product from adhering to the container wall.
