Ventilation & Extraction

Ventilation is the replacement of indoor air with fresh air from outside to maintain a good standard of air quality. Every enclosed workplace has a mandatory requirement to be ventilated with a sufficient amount of fresh or purified air. Whatever your specific requirements, our knowledgeable specialists will design and install the ideal ventilation system solution to best suit you.

There are various methods and technologies that can provide the level of ventilation required depending on the circumstances of your premises. There are natural ventilation systems and mechanical ventilation systems or combinations of both called mix-mode or hybrid systems. You can be sure that our dedicated team of experts will complete your project to the highest standards.

Natural ventilation refers to the action of removing and replacing air in an indoor area through natural processes. This is where there is no use of mechanical systems, for example, a fan. Outdoor air flow is utilised to provide ventilation through differences in pressure. Mechanical ventilation is where mechanical devices such as fans transfer fresh air into an indoor space and remove the stale air from inside.

This also refers to exhaust ventilation, positive pressure ventilation and balanced systems that use supply and exhaust ventilation. Mixed-mode or hybrid ventilation refers to ventilation systems that use a combination of natural ventilation. For instance, functional windows and mechanical systems that include exhaust, supply, distribution and refrigeration equipment.


Importance & Benefits

Why Ventilation is Important

Ventilation is required to not only provide oxygen to breathe, but it also dilutes metabolic pollutants such as the carbon dioxide that we breathe out. These pollutants result in poor air quality with increased humidity which can have a negative effect on people and property.

Inadequate ventilation increases the risk of transmitting airborne infectious diseases, such as tuberculosis. A buildup of indoor contaminants may cause headaches and dizziness as well as aggravating allergies and asthma, affecting the productivity of employees.

If a premises has negative pressure it can cause air from outside to be drawn in, this is called backdrafting. This could prove dangerous if there are fumes and harmful gases that need to be extracted. A ventilation system allows you to control the inside air pressure.

Benefits of Ventilation

Controlling air flow is a key benefit that a ventilation system provides you. Inadequate air flow will make the working environment unhealthy. On the other hand, too much air flow could make your heating inefficient and cause unnecessary spending on energy bills.

Reducing contaminants in the air improves the quality of the air indoors. Without ventilation, you will have a buildup of pollutants, such as carbon dioxide, bacteria and moisture. A good ventilation system will disperse pollutants and odours, replenishing the space with fresh air.

Reducing the temperature of the working environment is an obvious advantage but this becomes more important when you have a large number of people in the same area. By reducing the moisture levels with fresh air you can reduce the temperature and humidity.

Avoid condensation that can lead to mould and rot, which can eventually become an expensive issue to remedy. Damp conditions not only affect the property but can cause health issues like allergic reactions and problems with the respiratory system.

Ventilation & Extraction Options

At CICS we offer a wide choice of ventilation and extraction systems to suit any premises no matter the size or purpose. We have industrial fans for heavy duty use. These fans generate a vast amount of air movement in a reliable and efficient way.

The latest advancement in fans and blowers are industrial centrifugal fans. These fans take up less space as they are usually smaller. They offer outstanding performance, are extremely energy efficient and have customisable components to enhance effectiveness.

Also available are High Volume Low Speed industrial fans which are perfect for commercial and industrial use as they are specifically designed for spaces over 10,000sq.ft. They are exceptionally economical to run and perfect for replacing multiple standard ceiling fans.

Should your premises not be on such a large scale then we have a variety of commercial unit ventilators to perfectly match all of your air handling requirements. We also undertake all aspects of the installation, including ductwork, for a complete end to end service.


You can expect nothing but the highest quality when you choose CICS for your project. We take great pride in the excellent service that we provide our customers. Our skilful team pay great attention to every detail to ensure your project is completed to perfection.
