What is the difference between an air knife and an air gun?
An air knife spreads the air over a wide line and is suitable for drying or blowing clean products or surfaces across their full width. An air gun directs the air at one specific spot for a powerful, focused blast of air. Which solution suits depends on what you want to blow away and over which surface.
- What is an air knife and how does it work?
"
An air knife blows air through a narrow slot as a wide, focused air stream over a product or surface. In combination with a blower, it helps blow away moisture, dust or other loose residue.
"

- Why use a blower with an air knife instead of compressed air?
"
A (turbo) blower with an air knife is an energy-efficient alternative to compressed air for drying and blow-off applications. Whether this offers an advantage in your situation depends on the required air volume, the pressure and the operating hours.
"
- Can DOVAC assess whether my product will be dry with an air knife?
"
DOVAC can assess with you which air knife set-up suits your product and process. The outcome depends, among other things, on the product, the amount of moisture, the line speed and the placement of the air knife. A test or demonstration can help to assess the result in practice.
"
- How do I choose the right length and blower for an air knife?
"
The required length depends mainly on the width of the product or surface you want to treat. The desired blowing force, the distance to the product and the line speed also determine which blower and which air knife are suitable.
"
- Should I choose a stainless steel or aluminium air knife?
"
A stainless steel air knife is often the best choice in environments where aggressive agents or gases are used. Stainless steel generally resists corrosion better than aluminium. The right choice of material depends on the type of agent or gas and the conditions in your process.
"
- Can an air knife be installed in my existing production line?
"
An air knife can often be integrated into an existing production line. The available space, the product width, the mounting direction and the required air capacity determine what the set-up looks like. DOVAC can help you think through the air knife and blower combination.
"
- Does DOVAC also supply accessories for mounting an air knife?
"
Yes, DOVAC also supplies the accessories needed to mount the air knife in the right location and position. Which parts are needed depends on your application and the desired set-up.
