Trapper is the easy to use digitally programmed drain and odor control dispenser. Trapper can dose and spray for every drain, deodorizer, or special dosing application you need. Trapper is housed in a splash-proof enclosure with a tongue and groove design that keeps electronics dry throughout use. Trapper is available in AC or DC models and connects to a separate battery pack or wall transformer. Easily switch between drain maintenance and odor suppression modes through simple programming changes.
