n: Slang. Refers to the electric fan installed near drill rig, used to dispel mosquito in the workspace.

n: A kind of center blower whose entry diameter is smaller than its exit diameter so that the velocity energy can be changed into force energy .

n: Unlike common three-cone bit,one of the three eyeholes of the blower fixed on the bit is enlarged and enforced. So the most affect is toward one orientation during cycling the drill fluid.

n: air blown into a furnace or other equipment by a fan or blower.

n: a blower that dispel the poisonous gas and flies or mosquitoes that it stands on the drilling floor or well mouth.

n: a special compressor used on two-stroke engines to supercharge the engines intake air and scavenge (remove) exhaust gases from the engine cylinders. The blower has tWo corkscrew-shaped (helical) rotors with blades (lobes) that rotate inside a housing. The engine drives the rotors with gears at about twice the engines speed. The rotors rotate in opposite directions at the same speed. As they rotate, the lobes compress air drawn through an air cleaner on top of the housing. The compressed air exits the blower from the bottom or the side of the housing and goes into the engines air intake manifold.

n: a centrifugal blower driven by exhaust gas turbines and used to supercharge an engine.
