Side channel turbine or brush motors?
For industrial vacuum cleaners, the main difference is the choice between brush motors that are used in commercial or professional vacuum cleaners and those that run using side channel turbines. The most important factor to consider is the designated use of the machine. When continuous or very frequent use is required, it is preferable to use models with side channel turbines as brush motors don't last as long and must be replaced over time. Side channel turbines don't present these problems, even when there are required to operate non-stop.
What does ATEX mean? And when do I need it?
The ATEX directive certifies the presence of the necessary requisites for vacuum cleaners, turbines and other machinery that can safely operate in the presence of gas, mist and or dust that could cause a risk of explosion. Coynco, as a manufacturer, is required to supply a suitable vacuum cleaner based on a prior declaration from the client stating the zone where the machine will be used. The presence and quantity of potentially explosive gas, mist or dust must be considered in order to define the characteristics of the environment where the vacuum cleaner will be used.
| TYPE OF SUBSTANCE | ZONE | DESCRIPTION | ||
| Gas, vapours or mist | Zone 0 | Areas in which explosive atmospheres caused by mixtures of air and gases, vapours or mists are present continuously or for long periods of time. | ||
| Zone 1 | Areas in which explosive atmospheres caused by mixtures of air and gases, vapours or mists are likely to occur occasionally during normal operation. | |||
| Zone 2 | Areas in which explosive atmospheres caused by mixtures of air and gases, vapours or mists are not likely to occur or only occur infrequently or for short periods of time. | |||
| Dust | Zona 20 | Areas in which an explosive atmosphere in the form of a cloud of combustible dust in the air is presnt continuously or for long periods of time or frequently. | ||
| Zona21 | Areas in which an explosive atmosphere in the form of a cloud of combustible dust in the air is likely to occur occasionally during normal operation. | |||
| Zone 22 | Areas in which an explosive atmosphere in the form of a cloud of combustible dust in the air is not likely to occur occasionally during normal operation but, if it does occur, will persist for a short period only. | |||
Some examples of sectors that require an ATEX certified vacuum cleaner::
- Timber industry
- Paint industry
- Shipyards
- Food and agricultural industry
- Chemical sector
- Laser technology
- Electrical industry
- Petrol and fuel
- Pharmaceuticals
- Cosmetics
- Arms or rifle range industry
The probably causes of risk are:
- Hot surfaces (overheating)
- Sparks
- Flames or hot gases (exhaust fumes)
- Spontaneous combustion of dust
- Electric materials
- Electrostatic charges
- Optic radiation
- Electromagnetic waves
- Radiofrequencies
- Stray currents
What type of maintenance does my vacuum cleaner need?
It is necessary to follow the indications for use and maintenance detailed in the manual that comes with the machine. Careful maintenance carried out after each use is important in order to keep the machine in good condition. It's also essential to keep the filters clean by moving the appropriate lever to operate the ‘shake filter' and add HEPA filters for intake of fine dust particles that pass through the primary filter.
How do I choose the right vacuum cleaner?
To be fully satisfied with your industrial vacuum cleaner, you must specify the exact tasks that the machine has to carry out. Coynco offers a range of specific products to fulfil every need and can suggest appropriate models for any type of job requested by the client. Every model is designed for a particular task that could be the removal of very fine dust particles, swarf and oil emulsions, dust that is damaging to heath, suction over long distances, centralised suction, bagging of intake material, use in the pharmaceuticals or food sector etc.. To obtain maximum performance and perfect cleaning it is essential to use the right machine for the job and our specialised staff at Coynco can provide a suitable solution for any kind of task.
Why is it important to choose the correct power for the job?
Coynco offers a range of vacuum cleaners from those that use 2 or 3 brush motors to side channel turbines with 2.2 kW single-phase, 3.4 kW single-phase or 5.5 kW dual-stage three-phase motors. It is incredibly important to choose the right motor for the job if you want the get the best performance from your vacuum cleaner. For example, fine dust is very light and therefore doesn't require such powerful suction so it is recommended to use a single phase turbine but with a filter that has a greater surface area to reduce the problems of rapid clogging. The more powerful vacuum cleaners, like the 5.5 kW or 11 kW models, are necessary for the removal of heavy materials that need a greater airflow.
When I use my vacuum cleaner, dust passes through the filter… what can I do?
In some cases, like removing dust produced from floor sanding, plasma cutting, in chemical, cosmetics or pharmaceutical industries or, more generally, in the removal of fine or very fine dust particles, it is possible that these particles are not retained by the primary filter and return into the atmosphere.
What should I do?
- Check under the filter for the following are in position: the holding ring with the rubber part positioned against the filter, spring and lobe-knob.
- Check that the inlet valve is screwed in sufficiently so that the seal around the filter is positioned against/in contact with the cover of the vacuum cleaner.
- If the problem persists after checking that the filter is correctly in place, the dust is probably too fine (less than 3 micron) and it would be advisable to install a HEPA filter inside the primary filter.
