Mega Electronics in its 10 years of experience in the construction of ventilation systems has completed over 100 sites in the ventilation segment of our installations for residential and administrative buildings and restaurants. Concerning residential buildings and restaurants, the type of ventilation equipment depends entirely on the engineering solutions that the designer has set in the specific project, according to the needs and requirements of the building. Depending on this, the various objects are made with square air ducts made of galvanized sheet metal and straight round air ducts - Spiro channels - spiral coiled, which allow visible installation, and at the request of the investor can be painted in RAL color. 

This type of installation is especially popular in restaurants, nightclubs, and more. Square air ducts allow the implementation of larger dimensions, which makes them indispensable in the construction of large building ventilation systems. This type of duct is for concealed installation chambers, fans of all types, including explosion-proof, valves, reg. Elements, filters, and everything necessary for the construction of ventilation systems of any type with different capacities and parameters. We offer and install equipment from leading world manufacturers in the field of ventilation equipment, and the materials and equipment we offer are accompanied by quality certificates and declarations of conformity!

Construction of ventilation facilities for residential, office buildings, and restaurants are offered individually! For this reason, to receive an offer for the construction of this type of system, in the first place you must have a project available and a CS to it, based on which you can receive a valuation from us. In case of an unavailable project, we can deal with the design of your specific site, but the design is paid separately and its price varies, depending on the size of the project, complexity, etc. Regarding the design we perform, you will receive the value after giving us an exact design assignment! 

After receiving a project and evaluating its base from us, you do not undertake at any cost to choose us as a contractor to build the ventilation system that is designed!
