Once this information is available, the type of fan best suited for the system can be chosen. Minimum Transport Velocity (MTV) The minimum velocity that will transport particles in a duct with little settling; MTV varies with air density, particulate loading, and other factors. These replacements will result in improved air quality in the areas of operation and reduce exposure to diesel emissions for the operators and occupants of these buses.
For this reason, the hood should be located so that contaminants are not drawn through the worker’s breathing zone. When using a capture or receiving hood, the hood should be located as close to the contaminant source as possible. Historically, air-conditioning has been used in industry to improve or protect machinery, products, and processes. Establish a program of periodic inspection The types and frequencies of inspections depend on the operation of the system and other factors.
Automobiles – The Clean Vehicles program, emissions inspection, diesel idling and retrofits, and general automobile emissions information. Volume Flow Rate (Q) Quantity of air flow in cfm, scfm, or acfm. Mechanical air-handling systems can range from simple to complex.
