Recommendations for use

• When connecting to a system, ensure that the inlet and outlet duct diameters match (250 mm inlet, 250 mm outlet).
• Use rubber seals or duct tape to ensure airtight connections and avoid air noise and odours.
• Adjust the speed to the required performance and noise level — for a quieter environment, do not run continuously at maximum speed.
• Mount the box securely, using vibration dampers if necessary, to reduce losses and vibration.
• Check inlet openings periodically for blockage (dust, leaves) and clean them.
• In areas with high humidity or dust, provide filtration before the inlet to keep the fan clean and operating long term.

Benefits

The insulated fan box AirFan ISO-Box 3250 m³/h offers powerful airflow with significantly low noise thanks to its internal foam insulation. It combines capacity with practicality — 250 mm inlet and 250 mm outlet, a wide temperature range, IP44 protection and a durable metal-and-foam design. This makes the model suitable for rooms requiring quiet yet efficient ventilation.
