Eko RV FlowLock - AC Backflow Preventor

Your cold air is escaping and you likely don’t even know it.
If your RV has multiple AC systems, you're probably losing cold air every time only one unit runs. That’s because standard ducted RV vent systems allow air to backflow into inactive AC units, sending your cooled air where you don't want it.

The Eko Flow Lock solves this problem with an innovative, passive design that automatically directs airflow where it belongs and only when it’s needed.

This magnetic backflow preventer snaps over your AC unit's blower port to stop air from escaping through the inactive unit while still allowing full flow when in use.

• Eliminates AC Backflow
  Prevents cold air from escaping through inactive units in multi-AC setups. Whether you're cooling the bedroom or the main cabin, your airflow flows only when and where it should.

• Tool-Free Installation
  Magnetic design installs cleanly behind your existing vent grille. No additional screws, cutting, or adhesives! Just an engineered fit that works.

• Modular System Foundation
  Designed as the core building block in the Eko Flow ekosystem, Flow Lock ensures compatibility with all future modular vent components and adapters, so your airflow setup can evolve without a full rework. (We aim to design every product this way due to constant innovation and evolving.)

• Engineered for Heat. Made to Last.
  Constructed with polymers that are heat-resistant and naturally insulating. This ensures the Eko Flow Lock is able to withstand high cabin temps while keeping conditioned air where it belongs.

If you’ve ever sat in your RV on a 100° day, you know: every little bit counts.
Without backflow prevention, your AC works harder while cooled air gets sucked into the external environment through your unused duct.
The Eko Flow Lock puts an end to that waste.
