Moffitt Corporation is the Global Leader in Gravity Ventilation since 1961. Gravity ventilation also known as natural ventilation is using physics to allow heat to rise and escape from the building, others also call this process a stack effect. The problem with many facilities is that there is not an effective process of heat removal. Moffitt provides several products that allows for ventilation naturally.

Other ventilation companies often use motor-powered fans to relieve the building of heat and smoke. This is ineffective in more ways than one. Fans are only able to pull air out that is within one fan diameter. That means the heat or smoke won’t be moved until it utilizes gravity’s force to rise towards that fan. Secondly, fan motors add costs and maintenance that natural ventilators do not. An estimated $400 is spent per horsepower per year. That means a single five horsepower motor will end up costing $2,000 in operation alone using electricity. That is if the motor runs perfectly all year and no additional maintenance is required.

Natural Ventilators once installed require no maintenance. No hazards of maintenance men climbing up to the roof for repair. These ventilators keep buildings weather tight allowing no rain or snow in. The ventilators effectively remove heat and smoke providing worker comfort and cleaner air while having a longer life than a fan.

Moffitt provides a whole line of natural ventilators including our continuous relief ventilator, the Labyrinth and the GreenRoo^®. Moffitt also provides free ventilation design as well as full turn-key solutions from manufacturing of products to project installation. The benefits as well as savings are endless:
