Grain aerator / Grain fan, Sumy region.

Air pipes are immersed ingrain in a checkerboard pattern with a distance equal to the height of the layer mounds of grain. A fan with a suction or discharge nozzle is installed on the pipe, depending on the operating mode.
For example, in winter, the aerator in the suction mode removes warm, moist air from the depths at the same time, forcing cold air through the upper layers, destroying the foci of self-heating as well as the tick. In the spring, warm air is fed from the outside into the depth of the layer in the injection mode to warm up the seed material.

The maximum depth of insertion of the aeration pipe into the grain mass is 2500 mm.

The height of the ventilated grain layer is up to 3 m.

The diameter of the aeration pipe is 130 mm.

Fan productivity in the working area - 2850 cubic meters per hour(//tractor-service.com)

The total pressure in the working area is 1360 Pa

Engine power - 2.2 kW

Overall length with fan - 2800 mm.

Weight with fan - 32 kg.
