Delta Faucet 621TPA3350-BL Electronic Lavatory Faucet Matte Black

Product Description

The DELTA FAUCET 621TPA3350-BL is a battery-operated electronic lavatory faucet equipped with proximity sensing technology for hands-free operation. Finished in matte black, it is designed for commercial lavatory installations where touchless activation reduces cross-contamination and improves hygiene compliance. The proximity sensor detects hand placement and triggers water flow automatically, eliminating the need for manual handle operation. Battery power removes the requirement for a hardwired electrical connection at the faucet body, simplifying rough-in for new construction and retrofit projects alike. Licensed plumbers and commercial contractors are the primary installers of this fixture type.

This faucet is suited for commercial restroom applications including office buildings, hospitality facilities, healthcare environments, and multi-tenant properties. The matte black finish is appropriate for modern commercial restroom design packages. Battery-operated proximity faucets in this category are commonly specified in ADA-accessible lavatory installations and high-traffic restrooms where hands-free operation is a code or facility requirement.
