Tips Side Channel Blowers

Various components are used in safety features for systems with vacuum pumps and compressors. In order to realise high operating reliability in your pump or blower, we will first show the safety mechanism for the side channel ventilator, implemented as a vacuum pump and as a compressor. This side channel ventilator must be protected against polluted air as well as overloading at excessive pressure. We will give you a few tips to support the safety features in your system.

  1. Always use a motor overload switch and never set it higher than the nominal current shown on the rating plate.
  2. A suction filter or an in-line cartridge filter prevents polluted air being extracted. The filter will need to be cleaned on a regular basis. This helps to prevent excessive pressure loss and potential overload.
  3. A safety valve, also referred to as a vacuum valve or over-pressure valve, protects your system against high pressure. A safety valve helps to prevent your system from overloading without interrupting the process. The set-up of the safety valve must be checked by measuring the inlet and outlet pressure using a manometer and by checking the motor current. Thus 100% of the ventilator's flow must pass through the safety valve. The vacuum valve can also be fitted with an extra filter so that environment air, which may contain incidental pollutants, does not damage the ventilator.
  4. A great amount of heat may be generated during the build-up of pressure or vacuum. Please ensure that the environment temperature does not exceed 40°C.
  5. When air is blown into or sucked from the open, noise dampers help to reduce noise pressure.
  6. Vibration dampers can help to reduce resonations in floors, walls and cabinets.
  7. By installing a manometer you can check the way in which your system operates and potentially detect polluted filters.
  8. If a permanent piping system is used, then one must implement expansion-compensators. Because the pipes warm up and cool down, they can introduce tension on the ventilator which may result in leakage or serious damage.
  9. Refer to the user manual for the service interval and include this in the installation's maintenance procedure.
  10. During the design phase, consider whether there is a risk of explosion (ATEX 153 zone) and whether the medium must be kept from the environment (gas-tight design).
  11. During frequency control, it is recommended to secure the motor using PTC’s. The high- frequency switching behaviour of the frequency regulator will always result in extra heat generation in the blowers' drive.
