Ventilating Fan Vs Exhaust Fan

Bathroom exhaust fans typically come in one of three styles.

Ventilating fan vs exhaust fan.

The exhaust fan is used to get rid of smoke polluted air produced in indoor whereas the fresh air fan is used for indoor ventilation and cooling. The inline exhaust fan works the same way as the standard exhaust fan but the design is different. In other words putting fresh air into a room and removing bad air is ventilating a room. The exhaust fan is made up of iron based material whereas the fresh air fan is made up of plastic.

Direct drive exhaust fans have their motor mounted on the fan shaft so they are more compact and have fewer moving parts than belt driven fans. Exhaust ventilation fans on the contrary may cause the entry of radon and molds from crawlspaces or dust from attics fumes garages flue gases and so on. The window ventilation option is a minimum standard that can t be viewed as effective or reliable. If you draw air into your house and exhaust other air you could have cleaner air this way if the intake air is filtered but you will be losing a lot of your conditioned air thus raising your heating cooling costs.

Signs of bathroom ventilation problems. Another duct runs from the fan to a roof vent. It can be a serious problem when there aren t dedicated vents and the outdoor air moves into the house through holes and cracks. An exhaust fan is often referred to as a vent fan or ventilation fan so an intake ventilation fan is another specific fan.

The inline fan is mounted to a joist in the attic. One duct runs from the fan to a ceiling vent. When you are deciding between a ridge vent or an attic fan consider the needs of the attic. Depending on someone to open a window to vent excess moisture is a dubious proposition especially in cold weather.

Ceiling mounted wall mounted or inline remote. Intake fan and exhaust fan or an open door and window are all creating ventilation. They run more quietly and allow greater control over fans speeds than direct drive exhaust fans. Choosing a ridge vent or an attic fan.

If you have suitable intake venting a ridge vent might be a better choice while larger attics and those with poor ventilation might be better served by an attic fan. The result is a cooler attic space with plenty of air exchange. A vent fan will always exhaust moisture more effectively. The exhaust fan have small blades whereas the fresh air fan have large blades.

Attic fans perform this ventilation by pushing hot air out into the environment while also pulling fresh cool air into the attic. Ceiling mounted fans are installed in the ceiling and vent into the attic or out.
