Cleaning the VMC is important and even essential. Although this task requires a lot of effort and time , the results are satisfactory because it keeps its network VMC constantly in good working condition and avoid a lot of damage .
The consequences of poor maintenance
To qualify for a long time the benefits of installing a VMC must regularly take care of it . Indeed, a VMC unmaintained engine can quickly deteriorate due to fouling. If it is not regularly fattened , the VMC produces a quite annoying noise.
Excessive dust or grease causes saturation of the air unhealthy for people who breathe volatile organic compounds ( VOCs). Misuse and especially the lack of maintenance of mechanical ventilation can cause fires due to excess fat in the ducts.
When they are full of dust filters and vents become less efficient , thus slowing the renewal of the air. For larger buildings , the air flow rate is set for the whole . If the ventilation fan vents are blocked, the other apartments are facing the air causing a spread of odors flow reversal .
Lack of lubrication can also cause seizure fan . The increase in consumption of the motor and lower flow losses are caused by loads . Its weak voltage can cause slippage or premature wear of the belt in the collective housing.
Cleaning a VMC
Daily subjected to dust, plant debris and deposit fat, VMC network must be thoroughly cleaned . At beginning and end of each heating season, you must remove the vents , dip in warm water containing a degreaser , rinse with clean water, then dry them up carefully .
This removal allows access to products that are cleaned with a clean cloth. To avoid contamination harmful to the operation of the fan, it will clean the filters with a degreaser added to soapy water. Each year, the impeller should be cleaned with a clean cloth moistened with water .
Some recommendations to better maintain a CMV
Some habits must be taken to avoid cases of depression of VMC. The noise from a VMC network is normally insignificant. But it can be very annoying when the system is not connected or when the fan blades are bent or even when components of the apparatus are dirty. To overcome these inconveniences , we must put in place a system maintenance and monitoring .
Per quarter, and humidity controlled self-adjusting should be cleaned while avoiding contact with the fixed parts of the air intake with water . Every 6 months , check the alignment in the collective extraction box ( containing the wheel ) and check the belt tension and clean the heat exchanger.
For VMC turbofan must renew filters while ensuring good provision, the brand and the model adapted to the installation. If possible, use every 2 years a technician to control the system. It will be the task of checking the air inlets , maintaining ducts and subwoofer block engine height, and control measures drawing and depression. The installation and maintenance of VMC must necessarily be entrusted to a specialist. It is not advisable to block the vents as condensation and water damage are caused by lack of ventilation .
