Kitchen Exhaust Fans

This site contain information and suppliers of kitchen exhaust fans

  Welcome to our site. Here you will be able to find suppliers of various types of kitchen exhaust fans.  These fans are essential for exhausting potentially toxic, stale, or odorous air from the household. Kitchen air can easily become harmful during cooking. Cooking generates smoke, moisture, and air born grease that needs to be exhausted to maintain air quality for a healthy environment. But wait, getting the wrong exhaust fan can be dangerous as well. Dangerous, you ask? Yes, dangerous.

  Kitchen exhaust fans are rated in units called CFM’s which stands for Cubic Feet per Minute. This means that a fan with a rating of 600 CFM, will exhaust 600 cubic feet of air per minute so long as there is enough air to move. And that’s the problem. Houses today are sealed so tightly that a house can become depressurized while an exhaust fan is running. In fact, the more powerful the kitchen fan, the more potential danger. This is why it’s important to get a unit rated for your specific needs. When a house becomes depressurized, air is sucked into the house from outside through chimneys, hot water tank vents, and fireplaces, possibly drawing dangerous air into the house instead of exhausting the toxic air out like they were designed to do. The problem is, this air should be drafted and exhausted outside instead of being sucked into the living space!

  So you see, the more powerful the kitchen exhaust fan, the potentially more air could be drawn in through those danger zones. In order for a kitchen fan to work properly, a house needs the same amount of air coming into the house as the exhaust fan blows out. It’s called make-up air. Older, draftier houses may not pose as much danger because, well, they’re draftier and air can sneak into the house through small air leaks throughout the framework, but could also cause problems by drawing air in from attics and crawl spaces possibly spreading insulation and mold spores throughout the house. Houses need make up air to equalize the pressure difference that a powerful kitchen exhaust can create. A pressure imbalance could cause the fan to work too hard, shortening its life and possibly overheating.

  It’s very important to use the properly rated fan for your house to help avoid this depressurization and harmful scenario. Most manufacturers have a guide to help you determine the size or power of fan for your size kitchen. Do not purchase a fan outside those recommendations and always buys from a reputable dealer. Remember to clean and maintain your exhaust fan also. This will ensure that it works at its optimum efficiency and also will help keep the fan from overheating due to grease and dust build up over time. Always remember to turn off the circuit before performing any maintenance.
