I was looking at Oneida’s Super Dust Deputy XL, the 6” version.on their website, they say “ ultra-high efficiency with integrated air ramp and 6" neutral-vane inlet”. I sent them an email just to confirm and this is what they replied:
Thank you for reaching out to us. Great question, The neutral vane technology is a feature included on most cyclone separators. The "vane" refers to an extension of the inlet pipe that protrudes into the cyclone body itself. Similar to an air ramp, neutral vanes reduce static pressure loss by better guiding the airstream and reducing turbulence inside the cone.
With our larger Cyclones such as the XL this area of the cyclone acts like a neutral vane. I have attached a picture of the area I am referring to for your reference. While we don't have a flat wall like on the 2" and 2-1/4" Dust Deputy, the functionality of the neutral vane is still present.
It does not have an air ramp but the neutral vane which is similar.
So they don’t have an air ramp and are trying to say they have a neutral vane.
how critical is an air ramp and neutral vane to the operation of a cyclone. I think I read somewhere that they can reduce the static pressure penalty of a cyclone?
I was hoping to get away from making my own cyclone …
Sorry for the different formatting. I can’t seem to modify it.
thanks,
