Credit industry must recognize that it is difficult to have assembly lines for all types of VMC-DF

This chapter is in part a lot of installation tips, tricks and photos on what I used in my house, that at least it's live and concrete.
It is very difficult to navigate when one starts like me to research the different VMC-DF present in the European market. I did not stay only in the hexagon as the best VMC-DF are not there, it is perhaps unfortunate but that's manfrotto tripod heads how.
I have investigated all over Europe (France Belgium Netherlands Germany Austria Denmark) is very easy with the internet and especially Google Google internet pages translator translator!
It is easier to list the VMC-DF without clone. By doing this blog I am still discovering clones when I peeled the subject on the VMC-DF in Europe. In most cases I am unable to say what the actual manufacturer (I speak licenses because I do not doubt that they are all connected in Asia ... almost).
Credit industry must recognize that it is difficult to have assembly lines for all types of VMC-DF (large, manfrotto tripod heads small, flat, tall, enthalpy, rotor). And then there are companies that specialize in the distribution of all kinds except for VMC-DF ... we must complete the catalog!
Illustrious clones (I give the French name) Akor-HR found that VMC in at least six different brands. The actual manufacturer manfrotto tripod heads should be Ithoo Daalderop (Holland) but I'm not sure! Cocoon2 (225m3 / and 300m3 / h) these two machines are found in at least five different brands. Two brands Brink (Holland) and Maico (Germany) certified DlBt these two VMC-DF but the French brand-Air France does not mention in its documentation! WRA 450 HR Ned Air-found manfrotto tripod heads under at least four different names (or brands?).
Maico & AEREX this is the same company at the same address. The two brands have their website and catalog. This is a merger manfrotto tripod heads of two companies (MAICO HaustechnikSysteme + Fresh Lüftungssysteme) and the choice to have a new name (AEREX HaustechnikSysteme). In this case competition manfrotto tripod heads is not working!
Zehnder & JE StorkAir it's the same holding (Zehnder Group), one in Switzerland and one in Holland. This shopping buddy is not new as there since 1937! The paradox is very different prices manfrotto tripod heads between the two brands and no luck in France we Zehnder with wholesale prices!
Zehnder & Zehnder Paul bought Paul but Paul trademark continues to exist. I had long in mind that it was Helios which bought manfrotto tripod heads Paul, I read it in a forum at the beginning of my research.
It seems closer inspection that the PHI or certifications DlBt especially interested in Germany, Austria and Switzerland, and perhaps Holland. This suggests manfrotto tripod heads that manufacturers or brands are not certified or PHI DlBt machines intended only for export. This is the case for example of the 300 Thermos Paul is not PHI (info ou intox?).
I was frankly disappointed by French brands except Autogyre. I had the main answers "You are professional" or "You are a customer of ours," and finally "Contact your local dealer." I conclude that the French market is infiltrated by brands (Atlantic, Air France, ...) with the craftsmen installers.
Individuals installers manfrotto tripod heads do not really care the French brands. One of them clearly told me "It's company policy of France-Air" ... enough said! Besides the websites buying French brands are available only to "licensed" professionals.
We do not find this phenomenon in France, I know ... but I am convinced that it is worse in France. Perhaps also that since France is not clear what is happening elsewhere!
The well-known "free" based travel manfrotto tripod heads the turnover of 1 to 3 years practice. Almost all French brands make it against their "professional" clients. It is often for this silly reason that a professional will guide you on a brand over another! The problem is that if the brand is top in some areas, it is not in VMC-DF!
All professional French are not bad in installing VMC-DF but we have to find the good ones! It is best to ask for references on the subject manfrotto tripod heads and to make at least two visits
