How much energy can an air knife system save?

Compared to compressed air systems, blower-powered air knives typically reduce energy consumption by 50–75%, depending on application and operating conditions.

Are air knives suitable for food or packaging environments?

Yes. Oil-free blower-powered air knife systems are well suited for food, beverage, and packaging applications where cleanliness and consistency are critical.

Can air knives be customized for my production line?

Absolutely. Air knives can be sized and configured based on conveyor width, line speed, product geometry, and environmental conditions.

Do air knives require frequent maintenance?

No. When paired with high-quality centrifugal blowers, air knife systems require minimal maintenance and offer long service intervals.

Industrial Air Knives for Drying, Cleaning, and Cooling Applications

Industrial air knives deliver a high-velocity, uniform sheet of air designed to remove moisture, debris, and particulates from products moving along production lines. Powered by high-efficiency blowers, air knife systems provide a cost-effective alternative to compressed air, reducing energy consumption by up to 75% while maintaining consistent, reliable performance. Hoffman & Lamson air knife solutions are engineered for durability, efficiency, and seamless integration across a wide range of industrial environments.

What Is an Air Knife?

An air knife is a precision-engineered device that generates a laminar (streamlined) sheet of airflow used to blow off liquids, dust, or debris from products as they travel on conveyors or through processing systems. Unlike compressed air nozzles, blower-powered air knives deliver continuous, pulse-free airflow with significantly lower operating costs.

Why Choose Blower-Powered Air Knife Systems?

Energy Efficiency & Cost Savings

Blower-powered air knives consume 50–75% less energy than compressed air alternatives, resulting in substantial reductions in operating expenses and carbon footprint.

Uniform, High-Velocity Airflow

Designed for laminar airflow, air knives provide consistent drying and cleaning performance across the full width of the product, eliminating uneven results and rework.

Oil-Free, Low-Maintenance Operation

Paired with centrifugal blowers, air knives operate without oil contamination and require minimal maintenance, making them ideal for continuous-duty industrial environments.

Scalable & Customizable

Systems can be configured for specific line speeds, product sizes, and environmental conditions, supporting both new installations and retrofit projects.

Common Industrial Applications for Air Knives

Conveyor drying after washing or rinsing
Removal of dust, chips, or particulates
Cooling of parts after heat treatment or coating
Packaging line drying and preparation
Surface cleaning prior to labeling, coating, or inspection
