Mechanical Ventilation Systems & Services in Kenya

Walk into a busy commercial kitchen at lunchtime, a factory floor in full production, or a basement parking area with no airflow – and you feel it immediately. Heat, smoke, fumes, and stale air build up fast. Without proper mechanical ventilation, working conditions become uncomfortable, then unhealthy, then unsafe.

Isothermal Mechanical Engineering Limited designs, installs, repairs, and maintains mechanical ventilation systems for industrial and commercial facilities across Kenya. From kitchen hood installation in Nairobi restaurants to complete factory ventilation systems, we keep air moving the way it should – fresh air in, contaminated air out.

What Is a Mechanical Ventilation System?

A mechanical ventilation system uses fans, blowers, and ductwork to move air in and out of a building or workspace. Unlike natural ventilation — which depends on windows, vents, and luck – mechanical ventilation gives you controlled, reliable airflow exactly where you need it.

A well-designed system does three jobs:

  1. Extracts heat, smoke, fumes, grease, dust, and stale air
  2. Supplies fresh, clean air to replace what is removed
  3. Balances airflow so every area gets proper circulation without drafts or dead zones

Commercial Kitchen Ventilation

Kitchen Hood and Chimney Installation

Every commercial kitchen needs extraction that actually keeps up with the cooking line. We design and install kitchen hoods and kitchen chimneys that capture heat, smoke, and grease-laden air right at the source – over fryers, grills, ovens, and cooklines – and discharge it safely outside.

A properly sized kitchen hood does more than keep chefs comfortable. It reduces grease buildup on walls and ceilings, lowers fire risk, and helps your establishment meet health and safety requirements.

Exhaust Air Extraction and Fresh Air Supply

Extraction alone creates a problem: pull air out of a sealed kitchen and you get negative pressure – doors slam, burners struggle, and smells spread into dining areas. We pair exhaust systems with fresh air supply so your kitchen breathes properly. Balanced airflow means comfortable staff, efficient equipment, and happy customers.

Industrial Ventilation Solutions

Factories, workshops, warehouses, and processing plants generate heat, dust, fumes, and airborne contaminants that natural ventilation cannot handle. Our industrial ventilation services cover:

  • Fume and smoke extraction for welding shops, paint areas, and processing lines
  • Heat extraction for boiler rooms, furnace areas, and hot process zones
  • Dust and particulate control, including cyclone systems for separating particles from airstreams
  • General fresh air ventilation for large occupied spaces like warehouses and production halls

We size fans and blowers to your actual air volume requirements – not guesswork- so the system performs from day one.

Ductwork Fabrication and Installation

Ducts are the arteries of any ventilation system. Poorly made or poorly installed ductwork leaks air, rattles, collects grease and dust, and wastes fan power. Our in-house ductwork fabrication gives you ducts built to fit your building exactly.

Our duct services include:

  • Custom duct fabrication to your system’s specifications
  • Professional duct installation with proper supports, sealing, and access points
  • Duct maintenance — cleaning, repairs, and sealing of leaking joints
  • Airflow balancing so every outlet delivers its designed air volume

Ventilation Equipment We Supply

Need equipment for your own project or replacement units for an existing system? We supply:

  • Industrial blowers
  • Exhaust fans
  • Ventilation fans
  • Ducting materials
  • Air distribution accessories — grilles, diffusers, dampers, and fittings

Signs Your Facility Needs Better Ventilation

  • Stuffy, hot working areas even with doors and windows open
  • Smoke, steam, or cooking smells lingering long after production stops
  • Condensation on walls, ceilings, or equipment
  • Grease film on kitchen surfaces
  • Workers complaining of headaches, fatigue, or irritation
  • Dust settling on products and machinery
  • Failed health or safety inspections

If any of these sound familiar, a ventilation assessment is the right next step.

Frequently Asked Questions

What is the difference between mechanical ventilation and air conditioning?

Mechanical ventilation moves air – extracting stale or contaminated air and supplying fresh air. Air conditioning controls temperature and humidity. Many commercial buildings need both: ventilation for air quality and air conditioning for comfort.

Do commercial kitchens in Kenya need a kitchen hood?

Yes. Any commercial kitchen producing smoke, grease, or significant heat needs extraction through a properly designed hood and chimney system. It protects staff, reduces fire risk from grease buildup, and is a standard requirement in health and fire safety inspections.

Can you repair or upgrade an existing ventilation system?

Absolutely. We repair blowers and fans, seal and clean existing ductwork, rebalance airflow, and upgrade undersized systems. Often a targeted upgrade — a better fan, a redesigned hood, or additional fresh air supply – transforms performance without a full replacement.

How is a ventilation system sized?

Sizing depends on room volume, heat and contaminant sources, occupancy, and required air changes per hour. Our engineers calculate the airflow your space needs, then select fans, blowers, and duct sizes to deliver it.

Do you supply ventilation fans and blowers only?

Yes. You can purchase industrial blowers, exhaust fans, ventilation fans, and ducting materials from us directly — with technical advice on the right unit for your application included.
