You can meet many classifications dust collector on the market, but according to the most common classifications dust collector available. We can best dust collector four main categories: vertical dust collector, automatic dust collector, mini dust collector, vacuum box format and dust collector.

Vertical dust collector

This type of large-capacity dust collector, suitable for large floor area, floor mats especially since it also has rotating brushes.Characteristics of this type of dust collector motor are placed above the nozzle. Type large-capacity vacuum and high prices are consistent with the large utility area or office, at home choose to buy a dust collector stands also for this reason.

Vacuum box format

Compared to the dust collector, the dust collector stands compact box much, so it can clean all the nooks areas as television slots, corner tables, chairs, stairs.Features of the nozzle it is connected to the camera body using a long flexible tube.

This is kind of the most popular vacuum cleaners on the market today because it matches the conditions of use in the family.This type of dust collector compact, battery-operated or plug.

Since capacity is quite small so it’s only used to clean small areas such as the area on the table, sofa, computer, altar … The mini dust collector is now also quite popular because of the habit of using the dust collector was popular in many countries.

Automatic dust collector

This is a modern type of dust collector and its cost is high.Besides, it can only operate within the plane is not too wide. Vacuuming its effectiveness may suffer because of small capacity, features and capabilities are limited dust. Features of the dust collector Vacuum cleaners with bags and bags.

One of the important features of the dust collector is no bag or pocket. Dust collector with a dust collector bag is the type equipped with paper dust bags, fabric or fabrics often capable of deodorant, antibacterial.Cloth bags to help us save money because they can use multiple times, each finished with the clean laundry.

In contrast, paper bags can cost you an additional recurrent cost for paper bags to be thrown away after each use full.Some types of vacuum cleaners also use paper bags one according to the manufacturer’s standards. It without the kind of dust collector bags using plastic containers to contain dust. When the dust filled the box, you just need to remove the box and cleaned. The plastic box also makes it easy to identify when dust filled to bring the toilet.
Some of the comparison between the two types of dust collector bags and no bags to keep in mind are:dust collector are often cheaper than their pockets are not pocket, dust collector with bags often more durable, low maintenance, repair more

Vacuum cleaner bags do not usually have a larger capacity and better vacuum. Some kind of vacuum cleaner bags with self-closing function when removing bags, help you avoid smoking to dirt.
No bag dust collector can not have this function, dust collector bags are not usually noisier than the kind of bag
Lights dust

Dust warning light is also an important function and you should choose a machine with this function.When the amount of dust in the machine has plenty of dust warning light alerts and can help them clean it, avoiding the breakdown, due to excessive dirt trapped inside.

When choosing a power vacuum, you should be calculated based on the floor area which will operate dust collector. There are two types of vacuum power can make you confuse the power of the machine and the power vacuum.
The capacity of the machine is only the power consumption, and capacity vacuuming dust collector shown its capabilities.

For example, engine power recorder ~ 300W and 1200W power is 600W ~ 100W vacuum, ie machines operated in electric power consumption is 300W, the power draw of 100W it would be.Another important point is noted is not when the power consumption is also proportional to the power vacuum if the comparison between the different dust collector. Because vacuuming capacity depends on the detailed design of the machine.

Use a dust collector high electric power consumption low suction power that can make you pay for electricity costs that can not collect more effectively.Therefore you should consider choosing the type of vacuum cleaner with high suction power with the same power consumption.

Volume and loudness

Dust collector from 1 to 12Kg weight, but the vast majority of families in our country are choosing the type of vacuum cleaner 4 6KG volume.This volume, the elderly or young person can also be used. Noise is also an important criterion dust collector that loud noise can make you uncomfortable when operating.


Ability to filter dust is also an important criterion when choosing a dust collector.

The Principle of Operation and the Filtration Mechanism of Ro System !

RO is the abbreviation of Reverse Osmosis. The membrane is basically the main filtration mechanism made from polyamides. RO technology was invented and studied by a scientist Origin from the 50s of the last century with the purpose of serving mainly for the maritime sector and aerospace research in the United States. Then, RO system was fully developed in the 70s and is widely used for the production of drinking water, pure water supplying for food production, pharmaceuticals or laboratories. That is the origin of the reverse osmosis systems (RO).

The water purification technology currently with the membrane is used quite commonly from home water filtration system to the chain of water filtration system with large capacity in industrial zones. This system can eliminate 95 to 99 percent of all minerals and chemicals (dissolved solids in water). But depending on the water quality, before crossing the membrane, the water must be treated to minimize the possibility of congestion of RO membranes and protect the life of them. The information below will clarify the principle of operation and the filtration mechanism of RO system. Because understanding the operating principles of a product will bring great benefits to the users.

1. The principle of operation

RO systems operate under a mechanism that is opposed to the usual ones, thanks to the Earth’s gravity to create the penetration of water molecules through the capillaries of the filter core (such as Ceramic). The water pressure pressing water into a membrane called semi-permeable membrane is how the core process works. Based on the motion of the water molecules and the pressure of high-pressure pumps, RO membrane creates a strong flow (This might be called the dissociation of water in the normal environment thanks to pressure). Then, this system pushes the chemical components, the metals and impurities in the water to the low-pressure areas or drift downstream along the waste line (like the principle of operation of the renal system in the human body). The membrane is like a thick cellophane tape that is designed to let in only the water pass through and none of the contaminants because if these pollutants, most metal chemicals, and bacteria are larger than 0.0001 microns, they will be blocked.

2. The filtration mechanism

The filtration process is classified based on the pressure that pushes the impurities through the membrane, the features of a membrane and the size of the membrane’s capillary. Most RO systems look similar, yet the stages are different in each product. There are generally 5 stages incorporated into a process for optimal water quality.
The first stage (mechanical filtration): The membrane PP removes the dirt, dust, sand, soil, rust and other impurities suspended in water, which are larger than 5μm in size.
The second stage (activated carbon filtration -1): The small activated carbon filter removes some organic chemicals, pesticides, detergents, suspended impurities, unpleasant taste, color as well as the heavy metal impurities.
The third stage (activated carbon filtration -2): The filter with a block of activated carbon strengthens in removing the organic compounds, pesticides, detergents, suspended impurities, and unpleasant taste, color as well as the heavy metal impurities.

The fourth stage (bactericidal filtration): The ultrafiltration of reverse osmosis system completely eliminate the dissolved salts, heavy metals, bacteria and other compounds that are larger 0.0001μm in size as well as eliminate more than 96 percent of the salt in the water.

The fifth floor (activated carbon filtration -3): This is the last stage with the aim to remove the unpleasant taste completely. Besides, it also creates the sweetness and truly pure water.
Filtering water with a reverse osmosis system will remove minerals, color, dissolved organic substances, and other molecules. Moreover, it greatly improves the aesthetics of drinking water. The filtration process of reverse osmosis system is the perfect choice to produce pure water, pharmaceutical production and so on in order to optimally serve the needs of people, especially the scarcity of clean water currently.
