Aspiration Equipment
Local Aspiration
When the equipment is running, dusty air is drawn into the filter's dusty air chamber. Coarse and fine dust particles are deposited on the filter elements, then the purified air enters the purified air chamber and is discharged into the atmosphere through an exhaust fan. The dust deposited on the filter elements is returned to the product through a regeneration system (self-cleaning).

Overpressured dusty air flows from the storage tank or hopper scales to the filter in the dusty air chamber, where the dust settles on the filter elements. Then the purified air flows into the purified air chamber and is discharged into the atmosphere. Finally, the dust accumulated on the filter elements is returned to the technological flow (self-cleaning) through a regeneration system.
The dusty air generated in the receiving hopper flows into the dusty air chamber, where the dust settles on the filter elements, and the purified air flows into the purified air chamber and is discharged into the atmosphere through an exhaust fan. The dust deposited on the filter elements is returned to the product through a regeneration system (self-cleaning).
The flap system ensures that the product can flow freely into the hopper, but prevents dust from being released. Dusty air is sucked out of the hopper through cabinet-type filters and/or a centralized aspiration network. This system reduces the amount of exhaust air required to keep dust in the hopper, significantly increasing the efficiency of aspiration systems.
Centralized Aspiration
The dusty air flows through the inlet tube to the preliminary cleaning stage of the cyclone filter, gaining a rotational spiral motion. Under centrifugal force, the dust particles are pressed against the walls, losing speed and rolling down into the collecting cone.
The tangential inlet directs the inlet flow along the forming surface of the cylindrical filter housing. Such an injection generates a rotational motion of the dust-air mixture and the particles are exposed to centrifugal and inertial forces. Coarse particles of the mixture lose their velocity and roll down into the collecting cone. The remaining fine dust is fed to the second cleaning stage, i.e. the filter elements.
The dusty air flows through the inlet tube to the dusty air chamber, passing through the filter elements. The dust is deposited on the filter elements, and the air flows into the purified air chamber and is discharged into the atmosphere through the exhaust fan. The dust deposited on the filter elements is fed into the dust extraction hopper through the regeneration system. The dust is discharged from the hopper to the waste hopper or the technological flow through an outlet unit.
This system is intended for discharging the collected dust from dust separators and operates in dust collecting devices where the pressure is higher than the atmospheric pressure. The air lock is intended for discharging the collected dust from dust separators (both centrifugal and filter), and operates in both discharge and injection systems. Its main purpose (work objective) is to remove the separated dust particles from the dust collecting equipment and prevent air suction.
