56" 18-degree blade pitch 188x18mm 177.5RPM High blades are narrow but only slightly wider than modern fan company blades of say the cirrus hugger fan but this fan has steeper pitch and larger motor and its 56in not 52in so performance is surprisingly good considering the rpm and narrow blades however the blade pitch makes up for it i will make a pulchain version and a dc motor one soon and make more sizes
