Proof exhaust fan / Explosion fan / explosion rake / shovel proof Party

Security card sales professional manufacturer of explosion-proof tools exhaust fan exhaust fan is rotationally driven by a motor driven fan airflow, so a kind of air of indoor and outdoor air exchange regulation appliances. Also known as the ventilation fan. The purpose of ventilation is to remove polluted indoor air, adjust the temperature, humidity and sensory effects. Explosion-proof exhaust fan for explosive gas areas of tools, made of aluminum bronze, beryllium copper alloys. Widely used in petroleum, chemical, and other potential fire and explosion hazards in the environment, but also good mechanical machinery essential for the maintenance tools. Both qualities can play a proof function, and where beryllium alloy products can also play a shielded function. Currently in the domestic production, sales, distribution of explosion-proof tools to distinguish the material can be divided into two categories: 1. aluminum-copper alloy (commonly known as aluminum bronze) proof tools, specific material is a high purity copper matrix by adding an appropriate amount of aluminum, nickel, manganese, iron and other metals, copper-based alloy composition. 2. beryllium copper alloy (commonly known as beryllium bronze) proof tools, specific material is a high purity copper matrix by adding an appropriate amount of beryllium, nickel and other metals, copper-based alloy composition. Thermal conductive properties of these two materials are very good.
