ELECTRIC BLOWER -Red

Description

Focusing on product development for computer related equipment, thecompact axial fans from NIDEC SERVO are the result of technologicalinnovations that minimize noise to the greatest possible extent. NIDEC SERVO’s product designs incorporate several industry firsts,including specially molded 3-dimensional blades, and GentleTyphoon fanswith a unique blade shape. Market requirements are always researched andcatered to in advance; meaning customers always receive products thatperform well ahead of market rivals.

●●Versatile lineups of axial fans and centrifugal blowers Fans for high static pressure applications are also supplied as standard products.The aerodynamic characteristics required for fan motors differ dependingon the equipment in which they are installed, but may roughly be groupedinto airflow focus and pressure focus types respectively. The axial fans andcentrifugal blowers (also called “centrifugal fans” and “sirocco fans”), as fanmotors of NIDEC SERVO, fall into both the former and latter categories.Recently, NIDEC SERVO has also developed pressure focus type axialfans, suitable for use in high static pressure regions, in response to diversecustomer requirements.As its name implies, an axial fan generates airflow in the motor axialdirection. Airflow can be generated cylindrically by the propeller from theentire diameter of the fan, allowing considerable airflow generation. Theaxial fan sucks in air and pushes it out through the propeller blades, withoutlarge pressure (static pressure) output.The centrifugal blower, on the other hand, recovers the airflow released bythe impeller blades in a centrifugal direction from the motor shaft center viathe scroll casing (also called a “housing” or “frame”) and discharges itunidirectionally. This system effectively converts a centrifugal force intopressure, increasing the pressure (static pressure) to blow the air. However,only a limited airflow passes through the impeller, preventing a large airflowfrom being obtained. NIDEC SERVO refers to the former as fans and the latter as blowers,to easily distinguish the differences between the two types.In addition to these two types, NIDEC SERVO has recently released axialfans with features resembling those of the blower (high static pressureregion fans, e.g. the G1751M series). These fans are attracting the attentionof the IT industry and are highly rated as quiet products, capable of savingenergy with high-impedance equipment, with which conventional axial fanshave not been efficient.

●●Our ceaseless quest to reduce noiseNIDEC SERVO continues to introduce a never ending series of quietproducts to the market. People know to talk to NIDEC SERVO if low noise isa priority, and that reputation has grown over many years. Day and night,NIDEC SERVO is active in the research and development of low noisetechnology. NIDEC SERVO also swiftly introduced computational fluiddynamics (CFD) to deliver quiet fans and blowers that customers can usewithout worrying about designing noise reduction measures into theirapplication.

●●Versatile lineup of energy saving productsThe power consumption of fans may be problematic with some highairflow products and with large fans and blowers. When several units areused, a high capacity power source must be installed. NIDEC SERVOmarkets a large variety of high-efficiency fan motors that can reduce thepower capacity required for such machines.

●●Only highly reliable products are delivered to customersWith product liability in mind, it is the logical responsibility of manufacturersto supply highly reliable products that can be used by customers without anyproduct safety worries. Products with new designs are only supplied to themarket after their viability has been verified by subjecting them to variousreliability tests and proving that they are problem-free. Moreover, only high-reliability parts are used in the drive circuits of DC fans and blowers. NIDECSERVO develops and designs products by specifying the strictest deratinglevel in the industry.

●●Customized and semi-customized product specificationsProducts are supplied in optimum customized form for bulk purchases.NIDEC SERVO is capable of swiftly accomplishing optimum designs by fullyexploiting CFD technology. NIDEC SERVO will propose optimum semi-customized fans and blowers by combining its large variety of customizedparts. Let NIDEC SERVO devise a suitable solution to meet yourrequirements.

●●All NIDEC SERVO catalog products conform to the EU RoHS Directive All NIDEC SERVO products conform to the EU RoHS Directive byrestricting the contents of six specified hazardous substances (lead,mercury, cadmium, hexavalent chromium, PBD and PBDE) to belowtolerable values. (All products produced from the beginning of January 2006meet the RoHS Directive. Certain standard inventory products may includethose produced in and before December 2005. Please specify in yourpurchase orders that only RoHS-compliant products should be shipped.)NIDEC SERVO is also active in reducing another 18 hazardoussubstances.

●●AC and DC fansOne of the prominent advantages of AC fans is the fact that they can bedirectly connected to an AC power supply. The DC fan boasts high motorefficiency and is power-saving, as well as generating less heat, allowing theweight of the motor and venturi case to be reduced.AC fans and blowers use AC induction motors and are suitable forconstant speed operation. DC fans and blowers, meanwhile, use DCbrushless motors and can have highly variable airflow. By varying thevoltage supply, the speed is also easily adjustable. Standard DC fans andblowers regulated by variable-speed control are also available. See pages G-51 for further details.
