Air nozzle – an example of savings in air blowing
Many companies barely address the economics of air blowing. Replacing older blow-off devices, often homemade, with modern, energy-saving alternatives is a step forward.
The economics of air blowing is barely addressed by many companies. Replacing older blow-off devices, often homemade, with modern, energy-saving alternatives is a step forward. Correct design requires a clear understanding of what needs to be blown off and at what intensity. Continuous laminar flow suits some applications, while pulse blowing is increasingly used in more complex cases.
Our range now includes the DJPS air nozzle, which uses laminar flow along its effective length. Its operating economy depends mainly on the slot width, which can range from 0.05 to 0.20 mm.
Example comparing effective areas:
- DJPS nozzle (length: 25 mm, slot width: 0.05 mm) – S = l × t = 25 × 0.05 = 1.25 mm²
- Round nozzle (diameter: 1.5 mm) – S = π × r² = 3.14 × 0.75² = 1.76 mm²
At the same pressure, a greater volume of air is therefore likely to flow through the round nozzle’s effective area.
