Inlet Size

[Pete Petersen]

I've been researching different cyclone systems recently. I will be purchasing one in the next couple of months after we move into a new home. It seems that the concensus is that you need at least a 6" main on any good system.

I'm puzzled by the different sizes of inlets that manufacturer's (and You) have to offer. They range from 4.5" (Yours), 6", 7", 8", etc.

If the main needs to be at least 6" with a decent motor, why wouldn't you have at least a 6" inlet.

P.S. Thanks for getting this site and your products up and running! Hopefully they will both be a huge success.

Pete,
Our inlet size is really 6" round to a retangular chute measuring 4.5 x 9". That gives more cross sectional area than a 6" (28.324 sq. in.) round. There is a relationship between the intake chute size, the diameter of the cyclone, the size of the discharge pipe and the size of the bottom of the cone and the length of the cone. All of these proportions have been tested and found to be optimal for minium pressure drop and maximum separation efficiency. The inclined retangular chute with a relation of 1/2 diam high x 1/4 diam wide has been proven to be the most effective at reducing turbulance when the air hits the cyclone wall. Less turbulance equals beter separation and less pressure drop.

Thanks for the explanation, Ed. Sounds good to me. I look forward to purchasing from you as soon as I layout my new shop. Cheers!!!
