It is a well-known fact, that ventilation systems are installed in buildings in order to ventilate the rooms. The system is designed to supply or extract a certain amount of air to the rooms. Even with filters fitted to the system, it cannot be ensured that some contaminants will not come into the system. Contaminants are accumulated throughout the years, and can after several years build to a substantial amount.
The consequence is that the system may not work as designed. If the system, besides transportation of fresh air, also serves to heat/cool the rooms, it might become difficult to regulate. The accumulated dust creates a basis for bacteria and fungi. These might, within time, free themselves from the duct, and be transported into the ventilated rooms.
Blocked or heavily contaminated filters also create a basis for bacteria and fungi. The traces will over the time grow through and release on the other side of the filter. In this way they can reach the ventilated rooms. This might cause illnesses for the occupants working in the rooms.
The illnesses will show as mucous membrane inflammation, migraine, tiredness, depression etc. Poor indoor air quality does not only come from the ventilation system, but it definitely contributes to a large extent.
Ventilation systems do not only exist as comfort ventilation in offices, but are also used in the industry as suction for gases, smoke and dust. These plants are often very contaminated. Many of these plants have no direct influence on the indoor air quality due to the fact that they act as extracts. However the ducts can get blocked, and hereby cause poor suction from the rooms.
A dirty ventilation duct creates a fire danger. Dust burns very easily, and with suction in the duct system, the fire can spread out to other parts of the building rapidly.
Most people spend more than 70% of their time inside offices; buildings where only fresh air comes from air conditioning and ventilation system. We all depend on clean air to enjoy a health life. To ensure that the air is clean on your premises, particle and bacteria free, these systems must be cleaned regularly.
A standard dust content of 1 gram/sq meter has to be maintained.
In order to achieve that, we at EMCO have a high sophisticated machine to do that work.
With the new VT4000 Ventilator combined with our highly trained maintenance team, we ensure that your air-conditioning and ventilation systems are clean.
