A gas duster, also known as tinned wind, compressed air, or canned air, is a product used for cleaning or dusting electronic equipment and other sensitive devices that cannot be cleaned using water. This type of product is most often packaged as a can that, when a trigger is pressed, blasts a stream of compressed gas through a nozzle at the top.
A PZL-106 Kruk crop duster applying a fine mist A Mil Mi-8 spreading fertilizer. Aerial application, or what is informally referred to as crop dusting, [1] involves spraying crops with crop protection products from an agricultural aircraft. Planting certain types of seed are also included in aerial application.
An agricultural aircraft is an aircraft that has been built or converted for agricultural use – usually aerial application of pesticides (crop dusting) or fertilizer (aerial topdressing); in these roles, they are referred to as "crop dusters" or "top dressers".
Air compressor station in a power plant. In industry, compressed air is so widely used that it is often regarded as the fourth utility, after electricity, natural gas and water. However, compressed air is more expensive than the other three utilities when evaluated on a per unit energy delivered basis. [10]
Canned air / dusters do not contain air, and are dangerous, even deadly, to inhale. [24] Aerosol cans have three main areas of health concern: Contents may be deliberately inhaled to achieve intoxication from the propellant (known as inhalant abuse or "huffing"). Calling them "canned air" or "cans of compressed air" could mislead the ignorant ...
A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system.
3) into the gas stream as a conditioning agent has found wide use in recent years. It is theorized that ammonia reacts with H 2 SO 4 contained in the flue gas to form an ammonium sulfate compound that increases the cohesivity of the dust. This additional cohesivity makes up for the loss of electrical attraction forces.
The two major criticisms are the run off of fertiliser into streams and waterways which encourages marine plant growth, leading to choking of the waterways and altering the fresh water ecosystem, disadvantaging many fish, (and frustrating anglers). To minimise impact, topdressing is now prohibited within certain distances of water.
