As for the negative pressure fan, the analysis and explanation we want to perform on this product is its price. Because it is an important reference for our selection work, and the appropriate price is selected and the good product quality is guaranteed, then the user has a good price-performance ratio.

    In terms of negative pressure fan prices, the relevant factors are mainly the use of materials, motors, and fan specifications. Therefore, if you want to consider whether the price is appropriate, these factors must be involved and considered. Any of them, so as not to make the selection of negative pressure fan wrong.

    For the selection of the type of negative pressure fan, because it is closely related to the price of negative pressure fan, this work must be paid attention to. So, let ’s take a closer look at its specific aspects.

    Aspect 1: Outer frame material

    The material of the outer frame of the wind pressure fan is generally three types: galvanized sheet, plastic steel and FRP fiberglass. FRP fiberglass is also called glass fiber reinforced plastic.

    Galvanized sheet: its popular name is tinplate. It is used more because it is cheaper. However, there is a major disadvantage in that it has a short service life.

    Plastic steel: Although this material can be used, it is still not common from the current market situation.

    FRP glass fiber: It is a reinforced plastic, which has some advantages of its own, the main one is to have good corrosion resistance and high temperature resistance, and light weight. Therefore, its service life is longer than the above two.

    Aspect 2: Fengye

    For it, it is generally based on the material used. As for the blades of negative pressure fans, the material types are stainless steel, aluminum alloy, aluminum-magnesium alloy, and nylon plus iron. Among them, stainless steel and aluminum alloy are the two more commonly used. The main advantages of aluminum-magnesium alloys are high temperature resistance and high strength. Nylon plus iron is mainly used in some acid and alkali occasions. The price and cost of these materials are different, so the difference in the price of negative pressure fans is caused.
