I stumbled upon this review of Suction Controller while doing a routine search.
Senior Editor Carl Duguay of Canadian Woodworking & Home Improvement Magazine tested a Suction Controller CT SWITCHER-D in his shop and found it to be a significant innovation and beneficial in his work.
At first glance, these direct-mount suction controllers look just like a compact version of a Y-splitter. But instead of simply dividing the airflow between the two outlets, the SWITCHER-D lets you control exactly how much suction each hose receives.
He wraps it up with this conclusion:
the biggest appeal is that the SWITCHER-D is simple, effective and solves a major limitation of the traditional Y-splitter – variable suction control for each hose. That little bit of control makes for better dust collection, less hose swapping and a cleaner, more efficient workflow.
