Red Zephyr Inline Fan 4"

Why Choose a Red Zephyr?

EZ Adjust Radon Level, Variable Speed Advantages

The 12 volt dc Red Zephyr can be precisely and automatically (SMART) adjusted to deliver a precisely correct airflow rate. No over-ventilation or under-ventilation mold/moisture risk or wasted energy

Energy Efficiency Advantages

NASA grade ECM motor designed and manufactured for Red  Zephyr by experts deliver precise air delivery reliability. using about 1/3 the energy of 120 volt ac permanent split capacitor motors while delivering much greater performance accuracy.

Replace Costly Alternatives

Automatic SMART controls can allow a Red Zephyr to replace most expensive (but dumb) HRVs, ERVs, Dehumidifying Ventilators and Dehumidifiers while delivering a better result with greater energy efficiency. MORE
