Welcome to Go Cool Yourself

Some call these products “Big Fans,” others name them “HVLS Fans,” which stands for high volume, low speed.  At Schwank, we call them “MonsterFans.” Our fans move massive air volumes at a slow non-disruptive speed (typically from 0-120 RPM).

Monster Principle

Monster Comfort in the summer

That is what our little Monsters do. Our Monsters provide a cool breeze in hot summers by moving high volumes of air at a very low non-disruptive speed (HVLS fans). As the breeze passes over the skin, the fan can create an evaporative cooling effect of 5–7°F (3–4°C) throughout the space.


Cost savings in the winter

Monster comfort is our motto. You lose heat to the ceiling as warm air rises naturally. MonsterFans push the warm air down from the ceiling to the floor level where people work. If, for instance, the heating temperature is set to 65°F (18°C), your heating will work until it reaches 65°F (18°C) on the floor level. Eliminate destratification and distribute the warm air evenly throughout the building with our little monsters. Enabling your heating system to work less, and you, therefore, save substantial operating costs.
