High humidity is a big problem for the ventilation of a professional kitchen.
When preparing dishes by stewing or boiling, when boiling sauces and gravies, excess steam occurs. It is possible to endlessly list cooking processes with the formation of steam that is not needed indoors.
All of this vapor is drawn into the vent, condenses there, and causes droplets to fall.
And to prevent this from happening, you need to install drip catchers.
Or if a hydrofilter without a drip catcher is installed in the premises of a professional kitchen, then an optional drip catcher must be installed so that water does not flow from the ventilation.
Our hydrofilters are equipped with built-in drip catchers. But not all manufacturers do this, so you can buy drippers made of stainless steel from us.
By the way, drip catchers will be needed not only for restaurant ventilation systems. There are many industrial or commercial processes that cause increased evaporation.
