Define the ventilation purpose
Moisture removal, odour control, fresh air and process extraction are different requirements and may need different solutions.
Estimate airflow correctly
Room volume, occupancy, heat or contaminant generation, duct resistance and required air changes influence fan selection.
Plan the air path
Extracted air must be replaced. Consider intake openings, door transfer paths, duct routes, external discharge and noise.
Describe the room and duct
Send room dimensions, use, occupancy, duct length and bends, installation point and preferred operating schedule.
