  • Features a powerful 100 CFM permanently lubricated and sealed motor that's specifically designed for continuous use applications.
  • Housing mounts to joists directly or via adjustable mounting brackets for greater installation flexibility.
  • An integrated humidity sensor automatically triggers the fan's highest CFM setting until humidity levels drop to acceptable levels, ensuring adequate ventilation and preventing harmful mildew or mold buildup.
  • Compatible with a number of Broan multi-function and time control wall switches (sold separately).
  • UL listed and suitable for use over bathtubs and showers when connected to a GFCI-protected branch circuit.
Product Technologies:
  • Sensaire┬«: Broan's humidity-sensing technology has been integrated into the design of this bath fan, making it ideal for areas that see prolonged or regular exposure to moisture. The sensor will automatically engage the fan's highest CFM setting once the user adjusted humidity level has been reached to quickly ventilate the area until the reading drops to acceptable levels. However, even when those levels are reached, the user can set the fan to remain on for an additional 5-60 minutes after humidity has stabilized. This feature helps ward off harmful mold or mildew growth and keeps the room clean, fresh and dry.

Broan QTRE100S Reviews

Rated 5 out of 5 by from Must for small bathrooms Fan is quite, yet powerful. The humidity sensor is a must for any bathroom where steam is an issue. Most people turn exhaust fans off when they leave not allowing moisture to be fully exhausted. This fan stays on for about 20 minutes after a shower then turns itself off.

Rated 5 out of 5 by from I love the exhaust fan I am very happy with this fan. It comes on automatically as it is advertised to do and runs for about 20 minutes. If it still senses humidity, it will come on again and run about another 20 minutes. It is also wired to I can turn it on and off manually. It is also very quiet. Even tho it is more costly than other fans, I am really glad I chose this fan and happy with it's performance.

Rated 3 out of 5 by from More noise than I expected. Purchased expecting to be very quiet for the price. Much louder than expected after it was installed. Choose to install one fan mounted vertically. Manufacturer said the fan would not be covered by warranty if installed that way. Not that it would fail. Simply because it was never tested that way per the tech that I talked to. Cheaper fan that I had was not much louder. It does evacuate moisture and smell with in 3-4 minutes.

  • can this fan be mounted on wall in bath/shower inclosure?

    A. The Broan QTRE100S is approved for ceilings, and it can be put in a bathroom so long as it has a GFCI circuit breaker. Any installer should know about the GFCI and can get their hands on 1.
  • Can you also turn this on and off with a switch on the wall?

    A. The Broan QTRE100S can be hardwired.
