The so-called laboratory is a room used for experiments. Everyone knows that some harmful gases will be produced when doing experiments. If the exhaust effect of the laboratory is not good, these gases will remain in the laboratory and endanger the health of the experimenters.

Enhancing Laboratory Safety: Importance of Anticorrosion in Chemical Fume HoodsIntroduction:Chemical fume hoods are critical safety equipment in laboratories, providing protection for researchers and minimizing the risks associated with hazardous substances. One important aspect that significantly c

Industrial exhaust ducts are ductwork that connect range hoods to industrial chimneys through other components of the exhaust system such as fans, collectors, etc. Ducts are low pressure pneumatic conveyors used to convey dust, particles, shavings, fumes or chemically hazardous components in the air

Process piping transports large volumes of hot, dusty air from processing equipment to mills, baghouses and other process equipment. Process piping can be round or rectangular. Although circular ductwork is more expensive to manufacture than rectangular ductwork, it requires fewer stiffeners and is

In aeronautics, a ducted fan is a thrust-generating mechanical fan or propeller mounted within a cylindrical duct or shroud. Other terms include ducted propeller or shrouded propeller. [1] When used in vertical take-off and landing (VTOL) applications, it is also known as a shrouded rotor. [2]Ducted

In aircraft applications, the operating speed of an unshrouded propeller is limited because the tip speed approaches the sound barrier at a lower speed than an equivalent ducted fan. The most common ducted fan arrangement in full-size aircraft is the turbofan engine, where the power to turn the fan
