• Length of basic module: 2460mm;
• Inverted central ridge, increasing exhausting capacity by 20%;
• Products protected by copyight laws (INPI – Brazil).


Optionals at your disposal:

• Antibug and antibird screen;
• Translucent central ridge (policarbonate plates) to increase inner lighting;
• Mechanical or automatic dumper´s closing system for perfect control of air renovation/hour;
• Smoke Vent system;
• Inner noise reducer;
• Control of dust emissions to outside;
• Aluminum or steel colored finishings.


How it works:  
1. Outside air comes naturally in through side opening due to different temperature and pressure.

2. At the ceiling, inner pressure is bigger than outside.

3. Internal air, saturated and heated, comes naturally out through Robert´s ventilator.
