Specification BatteriesRequired : 1 Brand : Atlantic Water Gardens BulletPoint1 : Maintain maximum O2 levels in summer, gas diffusion in winter BulletPoint2 : Easy to clean air filter reduces particulates for motor longevity BulletPoint3 : Aluminum housing radiates and reduces heat to extend diaphragm life BulletPoint4 : Most cost efficient way to keep an area free of ice in winter BulletPoint5 : NEW FEATURE: DRY-RUN PROTECTION feature is integrated now in default. Pump works at rated voltage: When there exists no/ in-sufficient in-flow (or significant air bubble contained), it is DRY RUN scenario and protection will be triggered: Pump will access stop-run-stop-run---cycle, greatly reducing rotation. When flow comes sufficiently again, pump will re-access normal run. It greatly reduces physical friction between parts and heat generated, yet, not completely eliminate the impact.
