FIELD: process engineering.
SUBSTANCE: invention relates to air filter used in air ventilation and control systems. Room for equipment houses air filter with air duct. The latter makes toe channel between air filter inlet and outlet. Note here that air duct comprises inlet channel connected with outlet channel and coated with bristle extending from air duct wall across inlet channel at inlet channel section. Note here that bristle is oriented across the main direction of airflow through inlet channel. Note here that inlet channel is arranged to allow air suction in equipment room vertically upward through inlet channel from ambient medium to room inside. Note also that bristle can remove particles caught airflow in air duct and to let them fall from inlet channel by gravity. Invention relates to air filter used in air ventilation and control systems.
EFFECT: power savings, lower costs of repair.
