💡 What caused reduced vacuum pressure when connecting multiple dust ports together

Closed flow drops when too many intake lines stay open, so these caps help you shut down dead zones quickly. - Block empty hose runs to force maximum airflow toward active woodworking stations - Keep steady negative pressure inside central collectors and portable vacuums - Prevent dusty cloud drift across workbenches during aggressive material cuts - Extend filter life spans by lowering total particulate cycling through blower units ✝️
