DraftStoppa® TopHat™ AT100D (120V Export Model)

Top performance!
Top efficiency!

The DraftStoppa® TopHat™ is an innovative, energy efficient, ducted ceiling exhaust fan incorporating the Award Winning DraftStoppa® concept.

I fitted one of your DraftStoppa units to our ensuite fan about 3 weeks ago. This bathroom used to get so hot I could hardly breathe in there, after fitting your DraftStoppa the same bathroom is much cooler. I am now saving for another unit for our main bathroom. The DraftStoppa certainly works.
