In the south tower, the Trade Center's veteran rig operator, Roko Camaj, and an apprentice, Fabian Soto, were cut off near the roof and killed when the building collapsed. Their surviving colleagues are convinced that in the last moments before the tower fell Camaj was trying to use the cleaning scaffold to reach safety.
These fans move the air parallel to the fan's axis of rotation. The screw-like action of the propellers moves the air in a straight-through parallel path, causing a helical flow pattern. [citation needed] The three main kinds of axial fans are: Propeller fans - These fans are used to move large quantities of air against very low static pressures.
The axial fan is often contained within a short section of cylindrical ductwork, to which inlet and outlet ducting can be connected. Axial fan types have fan wheels with diameters that usually range from less than a foot (0.3 meters) to over 30 feet (9.1 m), although axial cooling tower fan wheels may exceed 82 feet (25 m) in diameter.

Air can be exhausted through pressurized hoods or the use of fans and pressurizing a specific area. [35] A local exhaust system is composed of five basic parts: A hood that captures the contaminant at its source; Ducts for transporting the air; An air-cleaning device that removes/minimizes the contaminant; A fan that moves the air through the ...
Blowers provide clean air to prevent contamination of electrical and optical surfaces from dirt, corrosive gases and overheating. Mains electricity is responsible for powering the blower’s motor. Different power ratings ensure that the required air flow is provided under different application conditions, duct pressures and hose lengths.
