Ventilation systems built according to the silo capacity andthe characteristic of the grain to be stored are installed into the concreteduring the laying of the foundation concrete. The secanals are coated usingspecially twisted and perforated Magnelis sheets specially designed for theproduct.

OBIAL uses ALFAN branded radial and axial fans in varyingcapacities to ventilate the products stored in the silos of varying sizes andcapacities.

OBIAL ventilation chimneys allow for the easy discharge ofdust formation and pesticides inside the silos. These chimneys are sloped, withwire curtains on their front surfaces. The securtains prevent birds and otherforeign objects from penetrating into the silos. And thanks to its sloped structure,it prevents rain and snow to penetrate.

Where more air outlet is needed, OBIAL produces aventilation fan with a wing diameter of 560 mm. This fan’s air suctiondirection contains a wire curtain, with the air outlet direction having alouvered structure. Louvers open during fan operation, and are designed so thatthey are shut when the fan stops.

 OBIAL also producesportable tunnel ventilation canals strengthened by corrugating and joiningzinc-plated sheets to solve the ventilation problems in horizontal grainstorages.
