There has been so much written on the use of air amplification technology especially when it comes to compressed air verses blowers. If you read anything from a blower manufacturer they look to be the best and if you read anything from an air amplifier producer, they seem to be the best. The truth is - it depends on the application. Same for cabinet coolers verses air conditioners. Static control devices and the seeming "miracle" air knives perform with them is not necessarily reality. One serious flaw is the use of simple (often over-priced by air amplifier suppliers) AC testers to determine if a static bar is working. All they really show is that you have electrical power going the static control devices. It does NOT indicate if they are producing the ions necessary for static elimination. Min Shang has articles already written in this web site to address blowers' verses compressed air, and static measurement. More will be added in the future to properly educate the customer in an unbiased manner and clarify many misconceptions with this technology. Visit our web site often for updated articles that can help you chose which technology, and which manufacturer is truly the best for your operation.
