Air Knife AIRMASTERS+

The AIRMASTERS+ air knife is designed for applications where very high blowing power is required, while at the same time taking into account compressed air savings and silence. The AIRMASTERS+ air knife creates a uniform and powerful blowing pattern along the entire length of the air knife.

The AIRMASTERS+ air knife utilizes the Coanda effect, which draws in external air and uses very little compressed air compared to the achieved blowing power. AIRMASTERS+ is our newest air knife model. Its patented design achieves a 50:1 amplification factor for compressed air. This means that the blowing volume is up to 50 times greater than the amount of compressed air used. This flow amplification factor is not available in traditional air knife models.

Description

AIRMASTERS+ air knife forextra powerful cleaning and cooling. AIRMASTERS+ air knives are made of anodized aluminum for durability. All our air knives use stainless steel adjustment plates. Air knives can be easily connected together using an extension kit if you want uniform blowing power, for example for a wide production line.
