Underfloor ventilation systems are the most effective available ventilation systems on the market.
They are characterized by a very individual system which can be tailored to specific customer needs. Underfloor systems always consist of a semi-circular duct and an underfloor cover. It has to be noticed that the concrete ground should in general be higher than the grate so that the loader shovel can be safely slide on the ground.
The underfloor covers are available in a large number of variants.
