Triple Bank Stormproof Ventilation Louvres - PL3 and PL3/DT

Mega Union’s triple bank stormproof louvre system is not only able to satisfy relatively higher ventilation requirements but also relatively higher rainproof performance requirements.

How does the triple bank louvre work?

1. Air and rain water enters through the spaces between the blades.

2. Rain water flows into the second, the third layer of the louvre and gets  intercepted by drainage channels.

3. Rain water flows along the vanes into the hollow upright mullions and gets discharged onto the base plate.

Product Specifications

The blade spacing of Mega Union’s triple bank stormproof louvre is 60mm. Its overall structure is made of anti-corrosion aluminium 6063T5. The louvre blades should not be installed by drilling or fastening with screws but wedged into the structural supporting mullion so as to allow expansion or contraction along the horizontal direction without being deformed or distorted. In addition, this will ensure a uniform appearance of the louvres. The maximum distance from the centre of the mullion should not exceed 1250mm. Support points along the vertical direction served to satisfy the actual air flow pressure requirement should be computed & specified by a structural engineer.

Installation Horizontal, vertical, horizontally inverted
Standard Materials Aluminium, stainless steel
Surface Treatment Powder coating, fluorocarbon coating
Supplementary Materials Mitred edge, silencer board (single-layered / insulated), acoustic components, anti insect net, anti bird net

Performance Summary

A multi-purpose ventilation louvre system that is able to achieve the lowest airflow resistance performance. The blades possess a streamline design without any sharp edges or protrusions in order to ensure the highest effectiveness of the air flow performance.
