Orion's all metal fans are ideal for military, chemical, process control and industrial applications. Since plastic fan blades can be susceptible to severe conditions such as high temperatures or chemical gases, metal fan blades are preferred in harsh environment applications for their durability. For harsh environment involving dust, moisture and other contaminants which may come in direct contact with fans, the IP55-rated sealing ensures safe, reliable operation and an extended operating life of the device.
