Three Stage Side Channel Air Blower

Air or gas is pulled into a side channel through the air inlet and is accelerated by an impeller rotating inside the impeller chamber. The resulting pressurized air or gas is discharged through the exhaust outlet. This type of operation is also known as a “ring” or  “side channel”blower design.  Both suction and discharge air passages drive to a toroidal chamber, where the radial blade impeller is located, representing the core  of the equipment. The fluid is forced inside the toroidal channel by the centrifugal energy given by the impeller and released towards  the inner side of the impeller blades where a further acceleration provides the fluid with an helicoidally trajectory with a consequent  progressive increase of energy. The pitch of the helicoidally trajectory changes in proportion with pressure variation between suction and discharge. The pitch is able to  self-calibrate according to the load acting on the fluid. The gas is free of pollution and keeps a linear flow without pulsations. The  absence of vibration and a low noise level are further advantages and contribute to ease the installation.

Make sure that the machine is shut down and locked against inadvertent start-up. Clean the external part of the machine with compressed air.  Deposit of dust on external blower surface avoid an adequate thermal exchange and can cause an overheating of the interior. Clean the ventilation grid of the motor fan cover. Dirt on motor fan cover reduces the air flow and causes motor over- heating. Every 10/15 days during operation it is advisable to clean the filter cartridge. If the machine operate in a high dusty environment, it is  necessary to replace it frequently. A dirt cartridge increases the pressure differential, the absorbed power and the operating temperature. If the machine does not produce any differential pressure, or too low pressure, or gas flow decreases, it is necessary to clean the inside of the machine.  Sealing rings and bearings replacement  The sealing rings lose the sealing capacity when exceeding their lifetime(max 2 years), thus allowing fluid losses. At that extend, sealing rings  must be replaced. Malfunctioning occurs when the bearings exceed their lifetime(max 2 years) causing excessive noise. At that extend, bearings must be replaced. Early wearing of bearings may be due to: -Mechanical shocks during running or stop that can damage the ball rolling track. -Running conditions over the limit of the nameplate causing temperature increase lubrication grease damage.
