Air Knife
High‑Velocity Laminar Airflow for Drying, Cleaning & Coating Control
The Menzel Air Knife delivers a powerful, uniform sheet of high‑velocity air designed to remove moisture, debris, and surface contaminants from textiles, nonwovens, films, foils, and industrial materials. Engineered for continuous roll‑to‑roll production, the air knife provides non‑contact drying, cooling, and surface preparation—ensuring clean, consistent material quality before downstream processing.
Using precision‑machined slots and controlled airflow dynamics, the Menzel Air Knife produces a stable, laminar “curtain” of air ideal for high‑speed manufacturing environments.
Engineered for Uniform, High‑Intensity Airflow
Menzel air knives are designed to deliver consistent performance across the full web width.
Key advantages include:
- High‑velocity laminar airflow for efficient drying and blow‑off
- Non‑contact operation to protect delicate or sensitive materials
- Uniform air distribution for consistent results across wide webs
- Energy‑efficient design using entrained ambient air
- Precise control of air volume, velocity, and direction
These systems support improved product quality, reduced energy consumption, and faster processing speeds.
Key Features
- Precision‑engineered slot design for stable, laminar airflow
- Air velocities exceeding 40,000 ft/min (application‑dependent)
- Coandă‑effect amplification for high output with lower energy use
- Stainless steel or aluminum construction for industrial durability
- Adjustable angle and standoff distance for process flexibility
- Quiet operation designed to meet industrial noise standards
- Compatible with blower‑based or compressed‑air systems
