Protect Your Attic With Master Flow Roof Ventilators and Exhaust Systems

Safeguard your insulation and shingles, while ensuring proper air flow, with Master Flow roof ventilators and other attic ventilation products. Roof or gable mounted Master Flow power ventilators save you more in cooling and heating costs than any other kind of ventilation. They remove the greatest volume of humid and/or hot air from your attic and feature a heavy duty screen, adjustable humidistat/thermostat, and an extra-long conduit for easy electrical hook-up.
