Electric fans selection
China’s range of electric fans includes desk, stand, tower, wall, ceiling and box models. The first two types dominate exports.The common components are the forward and rear mesh enclosures, fixed screws, blades, motor axes, oscillation buttons, control knobs, timers, switches and pedestals. Products may have mechanical or electronic controls. Popular desk fans come with grilles in diameters of 6, 14 and 16in, while stand versions have 12, 14, 16 and 18in counterparts. The blade and housing materials are among the factors that dictate prices. These are often sourced domestically, although imported variants can also be utilized for improved performance and durability. Apart from these, operational capability and added functions are key price differentiators. Low-end units go for $5 to $10 and perform only horizontal oscillation. The blades are made of locally purchased PP, and are more prone to cracking and deformation compared with equivalents from overseas. The motors often adopt cold-rolled or silicone steel plates. Some less expensive models also use tin components with inferior magnetic permeability and a shorter life span. Midrange electric fans have ABS, PP or transparent AS blades. The first material, together with iron plate, is also utilized for grilles and housings. The motors come mainly in locally procured cold-rolled steel plates. These appliances boast multiple speed modes, low-noise operation, LED screens, and wide-angle horizontal and vertical oscillation. Remote controls, however, are optional. In addition, small parts such as switches and timers are often plated. Prices are between $11 and $16. High-end releases have blades made of imported ABS or AS, and casings and fan guards in ABS or C25 steel from Taiwan. Electric fans in this segment are capable of double oscillation and five speed modes. Digital and remote controls, and timer functionality are likewise standard. A number of units are also equipped with LCDs or VFDs, ionizers or ozone generators, and cool and warm air output. Prices start at $17 and can exceed $40. As regards tower fans, most models come in 32 or 40in heights, have three low-noise speed settings and are fitted with a recessed handle for increased portability. These designs feature an advanced wind curve profile that enables maximum air distribution. Select units can simulate a natural breeze in different strengths. Washable filters that trap airborne dust and pollen particles may likewise be included. A number of products also boast remote controls and built-in bulbs to facilitate operation in the dark. Models exceed $10. Mini electric fans are available as well. Prices range from $0.30 to $3. Such releases have silver-coated ABS or PP housings, and perform 90-degree oscillation. Popular versions are equipped with three wind speeds, 12hr timers and remote controls. More expensive models boast ion generators, temperature sensors and LCDs, FNDs or LED screens. Products intended for promotionaluse, meanwhile, are handheld, run on batteries or via USB, and measure 5in. Prices of China-made electric fans increased by about 8 percent last year due mainly to rising material and labor costs.
