Recently, I worked with a customer that was looking for a way to make a difficult job easier, reducing stress and strain on the body and preventing injury.  The customer was in the Environmental Services & Hazardous Waste Management area and regularly was called out to service acid neutralization tanks. These are commonly found in hospitals, laboratories, and schools, to neutralize lab wastewater before it is discharged to the sanitary sewer.  The systems typically utilize limestone chips to aid the in process.

Periodic maintenance includes the removal and disposal of the spent limestone chips, tank cleaning and replenishment with new limestone chips.  Some of the tanks are tall and narrow, making access to the limestone chips difficult, especially near the tank bottom. Current procedures involved small shovels and unnatural body positions to try to reach the bottom-most material.  A better way had to be found.

The customer came across the EXAIR website and found the Line Vac product line. After watching the demonstration video, he knew he had found his solution!  The Line Vac is a compressed air operated device that turns any hose or tube into a powerful in-line conveyor. Based on the height of the tanks and the size and weight of the limestone, we agreed the 2″ Heavy Duty Line Vac would provide the power and durability to empty the tanks in a timely manner, and safely and efficiently.  The customer would use a tow behind compressor so that a reliable source of compressed air would always be available.

The Heavy Duty Line Vacs are available in sizes from 3/4″ up to 3″ in both smooth end and threaded connections for use with hose or pipe for conveyance.

To discuss your application and how an EXAIR Line Vac can make your transfer process easier and safer, feel free to contact EXAIR and myself or one of our other Application Engineers can help you determine the best solution.
