First Light Technologies, Inc. is a worldwide leader in the manufacturing of low pressure germicidal lamps and medium pressure UV lamps. The dust that is being generated by sawing glass with the diamond saw blades was too much for the competitors envelope bag type collector with an automatic shaker. Cleaning was ineffective and the customer had to manually “blow-off” bags every two days. The loaded filters resulted in reduced airflow and fugitive emissions from the saws. This compromised the shop cleanliness and the excessive maintenance required to keep the competitors collector running was labor intensive and costly.
