Electric Fan Manufacturer
Several of our experts mentioned this brand including Ron Harris owner of Del Mar Fans; Karina Lameraner, creative marketing director at digital decorating service Modsy; and Danielle Colding, designer at Right Meets Left Interior Design. They were impressed by the contractor plus model’s versatility and affordability.
This is when we start seeing Eck fans showing up that were made by Diehl Electric of Elizabethport, NJ. They peaked around 1915-16.
History
In the early 1890s the first electric fan manufacturer appeared in America. It was Eck of Chicago who marketed their 12″ and 16″ fans with cords and plugs that were a lot like what you see on a computer today. The April 10th issue of Electrical Age ran a woodcut of an Eck fan and noted that it came with either a standard plug or a special one, presumably the latter since the standard plug was too small for the larger motor.
In 1914 Diehl patented a fan motor that was much more compact than the prior models which were large and required a frame to hold them. He was also working on a gear driven oscillator which was more compact still. He was running out of space and Singer refused to let him expand in their building. So he bought his own building and moved in in 1918.
By the 1920s most fans had rounded blades and the motors were now all enclosed and smaller in size. Also by then the fans were starting to tilt so that they could become bracket fans for wall mounting.
In Hong Kong during the 1970s and 1980s Wing Tat (Yong Da Dian Qi Zhi Zao Chang) and Shell Electric Manufacturing were the largest manufacturers of electric fans. The former was a major exporter whose TAT brand of fans was sold worldwide while the latter produced its DEMC brands of fans in a six story, 93600 square feet Din Wai Industrial Building at 13 On Chuen Street in Fanling.
Technology
The electric fan is one of the earliest and most important electrical inventions. It’s a necessary building block for more advanced technologies like computers, lasers, large LED lights, petrol and electric automobiles and the space station.
The basic design of an electric fan is a motor with blades attached. When the motor is turned on it produces a stream of air that cools blow molding machine or ventilates a room. The motor is powered by a DC or AC current that passes through copper wire coils around a rotor (similar to the way that engines,cars and some water motors work).
When the coils turn, they rotate the rotor which spins the blades. The fan can be positioned in a cage or in a housing to prevent users from touching the spinning blades. Over time, fans have become smaller and lighter because the engineers figured out how to get more performance out of a motor with less copper and steel.
Some electric fans are also equipped with a variable-speed dial, mounted on the body of the fan or in a gang box at the wall. When the dial is set in a particular position, it varies the speed at which the blades rotate (similar to a dimmer switch for a light fixture). Many modern electric fans use a pull-chain along with this variable-speed control; the user can adjust both the fan and light with one chain.
Design
The earliest electric fans were big, bulky and had heavy iron/steel bodies. As the technology progressed these fans began to become lighter and smaller and far more graceful. The designers were also able to make significant improvements in the fan motor design and blade design that resulted in much better performance and efficiency.
Around the turn of the century a number of fan manufacturers were making significant advances in their designs. These included some of the larger well known names such as GE, Emerson Electric, Crompton Parkinson and Metropolitan. One of the most significant improvements was made by Ercole Marelli who not only started producing electric fans in Italy but significantly improved upon the original American designs.
In 1911 GE introduced their second gear driven oscillating fan which is referred to by collectors as the “kidney oscillator”. This model was a bit different from the earlier BMY fans in that it had a single front and rear bearing so the entire fan could be swiveled up and down or side to side.
GE would continue to refine this design over the next few years and it became quite popular. By about 1915 they had perfected the design and it would remain virtually unchanged until World War II. During the War, all electric fan production was put on hold as many of the manufacturers used their capacities to help the Nation with the war effort.
Applications
A fan is a machine that uses the force of air pressure to move air. Electric fans are powered by motors that turn a shaft on which there is an blow molding machine factory impeller. The rotation of the impeller creates air flow, and the airflow is induced by friction with the surfaces of the blades. There are two basic types of fan: axial and centrifugal. An axial fan moves the air in a direction perpendicular to the shaft, while a centrifugal fan blows the air in a sunburst pattern around the shaft. There are also mixed-flow fans, which combine axial and centrifugal flow.
Typical applications for electric fans include climate control and personal thermal comfort (e.g. an electric table or floor fan), vehicle engine cooling systems (e.g. in front of the radiator), machinery cooling systems (e.g. inside computers and audio power amplifiers), ventilation, fume extraction (e.g. in industrial heat exchangers), winnowing (e.g. separating chaff from cereal grains), and drying (usually in combination with a heat source).
The electric cooling fan has been recognized as a new generation product due to its small power consumption. As a result, it has been widely used in several industries. For example, the industrial blower fan sold by our company is suitable for several industries such as glass industry, paper industry, steel industry, cement industry, textile industry, metallurgical industry, and more.
