24V DC Cooling Fan manufacturing information

Time:2014-11-12 Click:573Times

1) Fan Size: mainly refers to "24V DC Cooling Fan" in size, generally a fan outside dimensions of length and thickness of the product, in units of mm. Fan Specifications Model name often size number, for example: DC8025, where 8025 represents the product size specifications 80 * 80 * 25MM.
2) Rated voltage: the fan is rated operating voltage under common universal voltage DC fan is 5V, 12V, 24V, 48V, and other specifications
3) Fan Speed: "24V DC Cooling Fan" degree rotational speed, in units of rpm (revolutions per minute), which is a more important parameter fans, high speed show can bring strong winds, manufacturers often standardized products, into ultra-high (U), high (H), the (M), low (L) and other speed products for users according to their own circumstances choose to use.
4) air flow: a quantitative indicators to measure the ability of a fan, in units of cubic feet (CFM), but some places identify units per minute cubic meters per minute (CMM), 1CMM = 35.31CFM.
5) Pressure: Peugeot Chi wind flow ability to overcome wind resistance, the index directly affect ventilation or cooling effect, in units of mm-H2O, some local identification unit inH2O, 1mmH2O = 0.03939inH2O.
6) Noise level: It is an important parameter, although nothing to do with ventilation cooling effect, but the use of different environments on the demanding, the unit is dBA (decibels). 7) bearing system: This configuration is the "24V DC Cooling Fan" soul parts, mechanical life is directly related to use of the product. Often divided into ball bearings and oil bearing.
