The Negative Pressure Ventilator (NPV), also known as a Smoke Extractor, is specifically designed to remove smoke, heat, toxic fumes, dust, and hazardous gases directly from enclosed spaces.
Unlike Positive Pressure Ventilation systems that force fresh air into a structure, NPV units create a vacuum effect by extracting contaminated air through flexible ducting
Note: This method is particularly effective in enclosed and hazardous areas where controlled smoke removal is essential.
