CYCLONE SEPARATORS from Gary MacIntyre Associates are offered with two inlet sizes, 4" and 6". The cyclone separators are designed to go between a woodworking piece of machinery, like a jointer or planer, and a dust collector. The cyclone doesn't have a fan motor since dust collectors are equipped with their own. Most dust collectors in the 650-cfm range have one inlet of 4". Larger units of 1,200-cfm have two inlets of 4", or by taking off the Y adapter, one inlet of 6". Since many machines have an outlet size of 4" it makes it easy to run a hose directly from the dust collector to the cyclone. The 4" and 6" cyclone separators are priced at $169 each.
