Kitchen exhausts fans are very important to keep the kitchen well ventilated. As we all know, smoke comes out whenever we cook. Also, the kitchen is the place where the sink is located. The sink is a perfect place for molds and mildews to thrives because of the wetness and moist. These molds and mildews may grow in the tile crevices and may pose health hazards to the whole family. Therefore, selected and installing a good kitchen exhaust fans should be seriously considered by the household.
The first thing to consider in selecting a kitchen exhaust fan is the fan’s cubic feet per minute (CFM). This can be done by calculating the volume of the kitchen and dividing the product by 15, which is the number of Air Changes per Hour (ACH) recommended by the Home Ventilating Institute (HVI).
It is extremely important to determine the varying BTU of ranges, whether it is gas or electric. In general, the rule is that for 10,000 BTU, 1000 CFM is the recommended kitchen exhaust fan standard.
Many ranges come with different kinds of hoods that help ventilate the kitchen and suck away smoke. These hoods have varying kinds of fans like a the model barrel shaped centrifugal fan or the traditional rotary bladed fan. There are also varying noise levels measures in SONES. Some have features for automatic shutoff, heat sensors and lighting effects.
Many professional homebuilders recommend that kitchen exhaust fans be installed with metal ductwork with all joints secured by high quality duct tapes. This is to ensure that fire accidents in the kitchen will be greatly avoided.
