Smoke Control & Mechanical Ventilation System

A Smoke Control & Mechanical Ventilation System is a life-safety and air management solution designed to control smoke movement during a fire and maintain safe, breathable conditions inside buildings. It helps protect occupants, support evacuation, and improve visibility for emergency responders.

1) Smoke Control System

Smoke control systems are engineered to limit the spread of smoke and heat in the event of a fire. Since smoke inhalation is a primary cause of fire-related fatalities, effective smoke management is critical.

Core Functions:

• Extract smoke from fire-affected zones

• Pressurize staircases and escape routes

• Maintain tenable conditions for evacuation

• Improve visibility for firefighting operations

Common Applications:

• High-rise residential & commercial towers

• Shopping malls & atriums

• Basements & parking garages

• Hospitals & airports

Typical components include smoke exhaust fans, pressurization fans, fire-rated dampers, control panels, and automatic integration with fire alarm systems.

2) Mechanical Ventilation System

Mechanical ventilation systems provide controlled air circulation to maintain indoor air quality, temperature, and pressure balance. Unlike natural ventilation, these systems use powered fans and duct networks to supply and exhaust air efficiently.

Core Functions:

• Fresh air supply and stale air exhaust

• Removal of pollutants, heat, and odors

• Temperature and humidity regulation

• Compliance with building and health codes

Common Applications:

• Commercial buildings

• Industrial facilities

• Underground parking areas

• Kitchens and utility spaces

1. Air Supply Systems
• Fresh air intake systems
• Supply fans and ducting
• Air Handling Units (AHUs)
• Fan Coil Units (FCUs)
• Variable Air Volume (VAV) systems

2. Exhaust Systems
• General exhaust fans for toilets, kitchens, or industrial areas
• Smoke exhaust fans (for smoke control during fire)
• Kitchen / fume hood exhaust systems
• Industrial process exhaust systems

3. Pressurization Systems
• Staircase / refuge area pressurization
• Corridor and lobby pressurization
• Elevator shaft pressurization
• Fire-rated compartment pressurization

4. Ductwork and Air Distribution
• Supply, return, and exhaust ducts
• Air diffusers, grilles, and registers
• Fire/smoke dampers integration
• Louvers and vents

5. Filtration & Air Quality Control
• Filters (HEPA, activated carbon, standard MERV filters)
• Air purification systems
• Humidifiers / dehumidifiers

6. Smoke curtains and smoke barriers
• Fixed Smoke Curtains
• Retractable / Motorized Smoke Curtains
• Vertical Smoke Curtains
• Horizontal Smoke Curtains / Smoke Canopies
• Perimeter Smoke Curtains
