A clear tube canister, filled with Prilled Soda Lime pellets, that will absorb acid fumes from either a drum or tote container.
 
The product functions in both directions. Absorbing the acid fumes, as well as creating suction ventilation as pumps draw down the chemistry. 
 
Easy to Use: Screw the unit onto the 3/4 inch female pipe thread of the tote or drum cap and installation is complete.
 
As the prills consume fumes, they turn purple. Prills last 1-2 years.
