Metal ventilation grill VELO

squareoutdoorcommercial

Overview
VELO is an external louvre designed for extreme conditions, delivering very high rain separation performance while maintaining low pressure drop and reduced sound levels. It prevents water ingress into ventilation systems and ensures durable operation in exposed and coastal installations. Optional integrated 230 V AC heating cable with dedicated control unit prevents ice build-up for winter operation. Enclosed junction box simplifies control unit installation.

Key features

• Rain separation efficiency >99% (EN 13030:2001, Class A).
• Low aerodynamic pressure drop to preserve airflow and reduce energy consumption.
• Reduced operational sound levels for quiet ventilation intake.
• Optional integrated 230 V AC heating cable with dedicated control unit for de-icing.
• Enclosed junction box for straightforward mounting of the control unit.
• Enhanced corrosion protection for coastal and salt-laden atmospheres.

Compliance & standards

• Rain separation tested to EN 13030:2001 — achieves Class A performance.
• Designed in accordance with VDI 6022 hygiene requirements to facilitate cleaning and maintain indoor air quality.

Benefits

• Prevents water ingress to protect downstream equipment and indoor environments.
• Maintains airflow efficiency while minimising energy use due to low pressure drop.
• Optional heating cable prevents icing and allows reliable winter operation.
• Corrosion-resistant design enables long-term use in coastal and exposed sites.

Applications

• External ventilation intakes for commercial and industrial buildings.
• Coastal installations and exposed façades requiring high corrosion resistance.
• Sites requiring high rain separation and winter de-icing capability.
