Product Specifications

Technical details and manufacturing context for Air Knife / Blower Nozzle

Definition

An air knife/blower nozzle is a critical component within separation mechanisms that generates a focused, high-velocity sheet or curtain of air. It functions to separate materials (like removing debris from products), dry surfaces, or clear particulates by utilizing compressed air or blower systems. In separation contexts, it often works alongside conveyors or processing lines to isolate components based on weight, size, or adhesion. The nozzle is typically manufactured from stainless steel, aluminum, or engineering plastics such as polyamide or acetal, allowing for a range of environmental compatibilities. Key parameters include operating pressure (1.0–1.6 MPa), air consumption (0.5–2.5 m³/min), nozzle width (100–3000 mm), air gap (0.05–0.5 mm), air velocity (50–120 m/s), operating temperature (-20–80 °C), material (AL6061 per ASTM B221), weight (1.5–15 kg), connection size (1/4–1 inch per ISO 7-1), and noise level (70–85 dB(A) at 1 m per ISO 3744). These values are reference ranges and must be verified for the specific model and application. The nozzle is selected based on required air force, width, and integration with existing systems. It interfaces with compressed air or blower systems via standard threaded connections. For procurement, verify model-specific values and standards with the legal manufacturer or supplier. Maintenance signals include reduced air velocity or uneven airflow, indicating clogging or wear. Failure boundaries include exceeding maximum pressure or temperature, which can cause seal failure or deformation. Always consult the manufacturer for application-specific guidance.

Working Principle

Compressed air or air from a blower is forced through a narrow, elongated orifice in the nozzle, creating a laminar or turbulent high-velocity air stream. This stream applies aerodynamic force to objects or surfaces, enabling separation by blowing off lightweight materials, liquids, or contaminants from heavier substrates. The air gap and pressure determine the velocity and force of the air curtain, which can be adjusted to suit the specific application. The nozzle operates within a defined pressure and temperature range, and its performance is influenced by the air supply and nozzle geometry.

Frequently Asked Questions

What is the typical operating pressure range for this air knife?

The reference operating pressure range is 1.0–1.6 MPa. However, the actual required pressure depends on the specific application and nozzle model. Always verify with the manufacturer.

Can the nozzle width be customized?

Yes, the reference nozzle width range is 100–3000 mm, and custom widths are available. Confirm the exact width needed for your application with the supplier.

What materials are available for the nozzle?

The nozzle can be made from stainless steel, aluminum, or engineering plastics such as polyamide or acetal. The material choice affects corrosion resistance and temperature limits. Verify material suitability for your environment.

How do I know if the nozzle needs maintenance?

Signs of reduced air velocity or uneven airflow may indicate clogging or wear. Regular inspection and cleaning are recommended. If performance degrades, check the air supply and nozzle gap. For detailed maintenance, consult the manufacturer.
