Blowing ventilation

Why a blowing system?
Similar to a suction system, a blowing system is suitable to store large batches. The use of forced ventilation makes that the system has a good drying performance. Moreover, the system is pretty easy to use, because the airbags are inflated easily.

How does it work?
Blowing and suction systems work similarly, only the airflow is reversed. A blowing wall has an opening between each 2 rows of boxes. The space between the boxes, and in front of the opening, is called the ventilation duct. It is covered by an airbag. In the ventilation wall the fans force the air down, creating an overpressure in the wall and in the ducts. This overpressure forces the air through your boxes and product. Any air treatment, such as heating or humidifying, occurs in the pressure wall. The inlet hatches are always positioned in the pressure wall, above the fans. The position of the outlet hatches is flexible.

Suction or blowing system?
Are you wondering what system fits your needs? Most systems are easily distinguished, and are suitable for different applications. But the blowing and suction systems have similar performances and applications, and a similar investment. A frequently mentioned advantage of a blowing system is its ease of use. Nevertheless, Omnivent usually advises to use a suction system. Why? Research has shown that the air distribution in a suction system is really better. And the better the air distribution, the less running hours you need to get all boxes in your store dry, and on the right temperature. That results in less dehydration and weight loss, and less energy use! So, blowing ventilation has a proper performance, but make sure you have considered a suction system too.
