When you know the site conditions but not the duty, pick a scenario: fill in room dimensions, air changes or extraction points and the system converts them into required airflow and pressure before matching models.
Process inputs to duty：Workshop ventilation, dust collection, drying and pneumatic conveying each ask only for the parameters they actually need
Conversion shown line by line：The calculation basis is printed line by line so the airflow can be checked by hand
Requirement verdict：You also get whether the duty is met and by how much, not just a model number
