When solvents and other chemicals are either poured into or extracted from a 5-55 gallon drum, air is displaced. This causes dangerous contaminated air to either be expelled from the bung hole or drawn into the drum.

The Electrocorp Air Scrubbing Drum Vents is screwed into the standard thread of the bung hole, the displaced air is forced through a particulate filter and a thick bed of  our VOCARB blend activated carbon chemical media where many gases, VOCs and odors are safely adsorbed.

The Electrocorp Air Scrubbing Drum Vents are shipped partially assembled. The caps are installed onto the body assembly which has been filled with carbon media. You will be able to rely on your sense of smell to determinate breakthrough. When this happens you will notice a very strong odor meaning the carbon can no long adsorb. The carbon at this point must be changed with the spent carbon being discarded in compliance with your local regulations.
