YWS pressurized blower is a double-section blower, which consists of two YWW fans. When the impeller of the blower passes the inlet end, it captures -quantitative air between it and the shell, and with the rotation of the impeller, the air is shifted sideways, and the pressure is gradually increased and then sent to the outlet end, which completes the primary pressurization and enters into the condenser to cool down the temperature, and then enters into the two-section blower from the other end of the condenser, and completes the secondary pressurization from the inlet to the outlet of the two-section blower.
