Every home has problem areas that need the right solution. Laundry, kitchen and bathrooms areas are especially prone to problems with humidity. This is mainly due to the presence of steam that emanates from frequent water use. Once this humidity reaches a certain level, it can wreck havoc on walls. Mold and mildew can destroy the entire structure of your home. To prevent this, it is important to use an exhaust fan. Find out more about how these fans work and what they do.

The Mechanics of Exhaust Fans

All fans work in the same fashion. Fans suck out hot air from an area and allow fresh air to enter. Once the warm air is pulled through the fan, it is pushed out the duct system. This prevents the air from recirculating in the room where it can cause more issues. There are even some fans that initiate on their own whenever its sensors detect steam. Direct drive exhaust fans are not as complicated as they seem.

How Well Fans Work

The effectiveness of a fan depends on its placement and the size of the room. Most exhaust fans are designed to work in smaller sized rooms. In some cases, it may be necessary to have more than one direct drive exhaust fan. Installation professionals can help you decide what is the most effective set up for your situation. It is important to know the exact measurements of the room to determine how many air changes are needed. Fan technicians can assist with this process.

Sizing Considerations

Exhaust fans are rated by their Cubic Feet per Minute (CFM) capability. This number tells you how much air the fan will shift per a minute. Interestingly, some small fans can shift as much air as larger counterparts. This is because they circulate at a faster rate. However, with faster speeds also comes with more noise. Thus, you really have to balance out what you want when selecting a fan.

A Final Thought

Fortunately, there is an easy formula you can use to help you select a fan. Simply multiple the volume of the room by the expected number of air changes. Again, if this is too difficult to figure out, contact a reputable fan sales company.
