How does a leaf blower work?

Question

I mean, how does the leaf blower take air from the outside and shoot it out so much faster? How does the electric pug-in or gasoline come into play? And on average, how fast can air come out of the leaf blower?

Answer 1

Well, for the most part. Leaf blowers use a centrifugal-type fan. Basically the blades spin the air around really fast, which creates a lot of pressure. It works off of the same principal as holding a gallon of milk at arm's length and spinning it around. The gallon gets a whole lot heavier feeling! Anyway, take that same pressure, funnel it down a small opening and you get a leaf blower. Some of the better blowers can put out winds speeds of over 250mph! But remember, wind speed isn't everything. The AMOUNT of air your are pushing at that speed is very important as well. Usually, gas blowers are going to be better at this. If you have a small yard and/or don't like the idea of maintaining a gas engine, then go with an electric. They have come a long way in the last few years and you can even get cordless rechargeable versions now, just don't expect the same performance as their bigger gas cousins.

Answer 2

It uses a squirrel cage fan to suck in air and blow it out at high velocity. They can reach air speeds of over 100 MPH.

Answer 3

A leaf blower works much like a hairdryer, but on steriods. A motor spins a fan that blows out the tube at high velocity.
