Why?
Airflow Requirements:
Wet shotcrete machines use compressed air to spray concrete efficiently. The required airflow depends on the machine's output and nozzle size.
A 40 m³/h shotcrete machine needs around 15-17 m³/min of compressed air to maintain a steady and efficient spray.
Pressure Considerations:
The air compressor should provide at least 7-8 bar (100-115 psi) to ensure smooth material flow.
Recommended Air Compressor Specifications:
Capacity: 15-17 m³/min
Pressure: 7-8 bar (100-115 psi)
Power Source: Diesel or electric, depending on site conditions
Tank Size: Large enough to maintain steady airflow
