Optima Flushometers are ADA compliant and feature the EL-1500-L self-adaptive infrared sensors, which meet every type of commercial and institutional restroom installation requirement for high traffic/abuse to low traffic/abuse traffic patterns. The dual-filtered by-pass handles harsh chemicals and debris. The flushometers use infrared sensing for "touch-free" operation in addition to lessening the risk of bacterial transfer onto plumbing fixtures.
