Frequently Asked Questions
What does CHANGESO manufacture?
CHANGESO is a leading Chinese manufacturer specializing in high-performance industrial drying solutions. Our core products include SC-AL (Aluminum) and SC-SS (Stainless Steel) industrial air knife systems, SC Series regenerative blowers, and the HAM series of 100% electric hot air generators designed for zero-emission thermal recycling.
How to calculate the required airflow for an air knife?
The required airflow (m³/h) for an industrial air knife is calculated using the formula: Effective Length (m) × Air Gap (m) × Target Air Velocity (m/s) × 3600. You can also use the free Airflow Matcher tool on the CHANGESO website for precise high-pressure blower sizing.
What are the maximum lengths for CHANGESO air knives?
Our SC-AL series aluminum air knives can be customized up to a maximum effective length of 2500mm. The SC-SS series stainless steel air knives can be customized up to 3000mm. Both series support standard adjustable gaps and maximum air velocities up to 200 m/s for high-speed drying lines.
