Portable airborne contamination control system including a main and remote unit

This invention describes a portable system for capturing airborne contaminants like overspray and fumes. It features a main unit with a motor and filter that creates suction, drawing polluted air through a flexible hose. This hose can connect directly to the main unit or to a small, highly portable remote unit, which allows the system to reach difficult areas. The main unit filters the air and exhausts it, and the claims specify that the remote unit's inlet can accommodate either one or two articulated suction ducts.

Why it matters: Filed before significant advancements in filter media and motor efficiency, this system could now be built with improved contaminant capture and reduced power consumption. Lighter, more durable materials also enhance the portability and ruggedness of the remote unit, making it more practical for diverse applications.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateMotor, fan, filter, custom cabinet, articulated ducts
