High Efficiency Airknives

What Are High Efficiency Airknives?

High Efficiency Airknives (Air Knives) are typically used in blow-off and drying applications that require high velocity air to remove dirt, debris and surface moisture from bottles, cans, and various fabricated parts.

The "XJ" and "XJS" High Efficiency Airknives can be powered by a blower and these air knives are capable of delivering exit air velocities of up to 38,000-fpm or 400-mph.
