Side Channel Blowers SEKO’s range of side channel blowers are an effective solution for air displacement in many applications. Side channel blowers are the first choice in many automation projects for applications that require large volumes of clean, dry air to be moved with low pressures and voids. SEKO‘s product offering features ease of installation like our other products, with low operating noise levels and low energy consumption.
Side channel compressors and vacuum pumps Side channel blowers work on the principle that lateral channels can operate both in suction and compression, and are designed to work in continuous service. The impeller is mounted directly on the motor shaft and this, together with a housing specially shaped to form the side channel, provides frictionless operation. SEKO’s side channel blowers are constructed of diecast aluminium, guaranteeing maximum robustness and easy handling. Lubrication is not necessary because there is no contact between static and rotating parts. The pumped medium is sucked in and compressed which makes it is possible to use a side channel blower to generate both a vacuum and blast air. The rated power of the engine determines the maximum differential pressure of blower. The silencers installed on the sides of the supply and exhaust system ensures quiet operation. Maximum operational reliability, even with high differential is ensured by having the bearings outside the compression chamber.

Motor advantages All SEKO blowers use 2-pole motors with the range including both singlephase and three-phase motors. Dual frequency (50/60Hz) makes the devices usable in many regions of the world, while the design choice of placing the bearing outside of the compression chamber allows them to tolerate high working temperatures and improves the reliability and service life of the blower. The machines are suitable for operation with inverters.
Performance advantages The precision machine tool cutting ensures the accuracy and quality of the blower and all products go through a strict mechanical and electrical performance test. By using PROE, UG, CAD and other computer-aided design software and motion simulations, designers can test and validate all features and performance of the devices prior to production commencing.
Product design advantages After moulding for die-casting of aluminium alloys, the machining of completed parts and the accurate cutting process guarantee an improvement in terms of precision compared to traditional technologies. The design of the impeller improves the overall performance of the machine, while its IP55 protection and class F electrical insulation make it suitable for hundreds of applications all over the world.

Operating principle The impellers are mounted directly on the motor shaft for non-contact, frictionless compression. Maximum operational reliability, even at high differential, is ensured by the arrangement of the bearings outside the compression chamber. The gas is taken in through the inlet. As it enters the side channel, the rotating impeller imparts velocity to the gas in the direction of rotation. Centrifugal force in the impeller blades accelerates the gas outward and pressure increases. Every rotation adds kinetic energy. This results in the further increase of pressure along the side channel. The side channel narrows at the rotor, sweeping the gas off the impeller blades and discharging it though the outlet silencer where it exits the side channel blower.
