Utilizing its patented delivery system, this TCell Dispenser consistently delivers a precise dose of high-quality fragrance blended with Microtrans, a true odor neutralizer, for 60 or 90 days without the use of batteries. Natural airflow distributes the odor neutralizer throughout the room so the dispenser is ideal for high-traffic areas with good airflow. Because even the cleanest washrooms are susceptible to unavoidable odors, a discreet, effective, air freshening system is essential. This cost-effective, passive air-care solution offers compact, silent operation & instantly enhances the image of any environment. It is easy to use with no programming required. Tamper-resistant design contains a unique, 90-degree spill protection. One dispenser covers a washroom with approximately three to four stalls / fixtures (6,000 cubic feet).
