Publication number: 20240183412Abstract: A brake air through flow and brake dust collector system for a brake installation includes an air duct connected with a brake air receiving element at a brake installation that receives brake air in the vicinity of the brake installation and transports the air to a distal environment. A brake air through flow device has a cyclone separator element, a collecting element and a filter element. The brake air through flow device separates and collects dust particles from the brake air flow and filters the brake air flow thereafter. A suction element generates a suction pressure to the brake air receivable from the brake air through flow device to generate a propulsive brake air flow through the brake air through flow device and extends the suction pressure to the brake air receiving element. The brake air through flow device and the suction element are arranged at the distal environment.Type: ApplicationFiled: November 30, 2023Publication date: June 6, 2024Inventor: Wieslaw Strzala
