A dust separator including a top member having a top member having an inlet port arranged to supply dust-laden air and an outlet port arranged to remove clean air, the top member having a lower portion configured as a lip and having a radius which equals diameter of the inlet port, and a dust separator plate, housed within the lip, having a passage with at least one opening arranged to remove the dust from within the top member.

The cyclone separation device has a case (1), a space partition plate (7), and a cylindrical member (11). The case (1) is formed into a cylindrical shape and has a first intake port (4), an outflow port (6), and a second intake port (5).

The first intake port (4) has a circumferential opening (2) circumferentially formed in a side surface on a side of the one end of the case (1), and a fixed blade (3) arranged along the circumferential opening (2). The outflow port (6) is disposed on a surface on the side of the one end and discharges the swirling airflow fed through the first intake port (4). The second intake port (5) is disposed on a side surface on a side of the other end opposite to the one end.

A reservoir tank includes: a tank chamber for storing a cooling fluid; a gas-liquid separation chamber provided adjacently below the tank chamber in a vertical direction; a partition wall for partitioning the tank chamber and the gas-liquid separation chamber; an inflow pipe for sending the cooling fluid into the reservoir tank; and a discharge pipe for discharging the cooling fluid from the reservoir tank. The inflow pipe and the discharge pipe are connected to the gas-liquid separation chamber, the gas-liquid separation chamber has a cylindrical outer peripheral wall, the cooling fluid sent in from the inflow pipe to the gas-liquid separation chamber flows along the cylindrical outer peripheral wall in a curved manner so as to rotate around a vertical axis, and is guided to the discharge pipe, the partition wall is provided with a communication hole communicating the tank chamber with the gas-liquid separation chamber, and the communication hole is provided at a position closer to a central axis of the cylindrical outer peripheral wall than to the cylindrical outer peripheral wall when viewed in the vertical direction.

In an example, an air filtration apparatus includes a cyclonic particle separation chamber having a first inlet to draw air from a first region, second inlet to draw air from a second region, and an exhaust port. The air filtration apparatus may further include a pressure sensor to sense a pressure of the first region, and a cyclonic air flow controller. The cyclonic air flow controller may control an air inflow received via the second inlet in response to an output from the pressure sensor to maintain a total air flow rate via the exhaust port.
