3 Things to Look for in Air Knives

We recently expanded air knives and after exhaustive training and research I wanted to pass some knowledge to our community. For those of you who don’t know an air knife is a non contact method of drying used primarily for drying and debris removal. This is done by focusing compressed air through small outlet channel, to produce a sheet of high pressure air flow.

Some of the things to consider when choosing an Air Knife:

1. Size: One plant uses air knives to clean bottles coming down a manufacturing line, while another uses several of them in series to dry the paint on vehicles. So, it’s important to have an idea for the amount of surface air that needs to be covered.

2. Air pressure Velocity:  This may seem like common sense, but the further you position the air knife from the actual item the lower the blow off pressure. While blow off pressure is important, the distance the unit will be placed from the subject material can be even more important.

3. Noise: Not all air knives are rated for OSHA noise specifications, trust me you do not want a loud whistling sound piercing your ears every time you turn the system on.

It is also important to make sure you have an air compressor that can supply the 100 PSI the air knife needs to effectively function.
