What Are Vacuum Cleaners?
A vacuum cleaner is a cleaning tool that sucks dirt and dust through an air inlet.
The performance of a vacuum cleaner depends on its suction power and the size of the dust that the filter can filter (diameter of the holes).
It can be said that the better the suction ability to suck in dust and the smaller the size of dust that the filter can filter, the better the performance.
There are two types of vacuum cleaners available: commercial vacuum cleaners with 12~30 liter capacities and industrial vacuum cleaners with 30~170 liter capacities.
Applications of Vacuum Cleaners
Vacuum cleaners are mainly used in the food, pharmaceutical, medical, chemical, precision instrument, electronic, construction, hotel, office, and metal, automotive, concrete, and industrial waste industries to clean up hazardous dust in the work environment.
Examples of applications include:
- Metalworking, steel mill dust
- Industrial production cleanup
- Food factories
- Pharmaceutical plants, clean rooms in pharmaceutical facilities
- Clean rooms in laboratories
- Dust in workshops and for DIY, ready-mixed concrete plants
- Cleaning of warehouses, shells, bicycle parking lots, demolition and renovation sites
- Cleaning of control components, electrical components, PC components and peripherals
- Cleaning of buildings, offices and stores
- Cleaning of gardens and artificial turf
Principle of Vacuum Cleaners
The vacuum cleaner consists of three parts:
- An inlet part (air inlet) where air containing dirt and dust comes in.
- The filter part (dust catcher made of filter material), which removes dirt and dust and allows only clean air to pass through
- The vacuum cleaner, which creates a weak level of vacuum by the rotation of the motor.
Filters used include synthetic fiber filters, cartridge filters, sponge filters, and sludge filters.
The blower, connected to a motor that rotates more than 10,000 times per minute, blows air out of the vacuum cleaner like a ventilation fan.
As a result, the interior of the vacuum cleaner becomes lower than the outside air pressure, creating a vacuum. Since gas has the property of moving from high pressure to low pressure,
outside air with high pressure is sucked into the vacuum cleaner at low pressure along with dust.
Contaminated air sucked along the hose collects in a dust bag (filter) with micro holes. Only the clean air that can pass through the fine holes passes through the filter and
goes out again through the exhaust port, leaving only dust in the filter.
