How The Vacuum Cleaner Works?

Vacuum Cleaner Functionality

The air pressure makes it Operation Air is the alpha and omega of a sucker. With compressed air, dust and dirt are sucked in, there is the separation of the dirt particles and filtering ensures pure exhaust air.

In principle, the vacuum cleaner operation is easy to explain: suck in air, filter, and blow out air again. But of course there is a lot of sophisticated technology behind this mechanism, otherwise we would constantly be standing in a cloud of dust while vacuuming.

The engine of a vacuum cleaner works with a fan, which generates the suction air by vacuum, with which then can be sucked.

Different technologies determine the way of working

However, the operation of the best buy vacuum cleaners reviews motors may vary from device to device. This is also related to the development of the bag less vacuum cleaner, which is considered a small revolution under the suckers.

In the Compressor technology powerful fan blades work on the required pressure and the cleaning of the air, the cyclone technique produces a strong air vortex, with which dust and dirt from the air are hurled. The filter plays an important role in the exhaust air.

Bag suction and bag less suckers

With bag suckers the dirt particles get into the dust bag, which sits in the housing of the device and can be exchanged. The bag less vacuum cleaner transports everything into a container, which is then emptied. The bag less vacuum cleaners use single-cyclone motors or multi-cyclone motors.

The multi-cyclone technique differentiates between coarse and fine dirt, so that multiple filtering takes place. The applied HEPA filter systems with special coating are a blessing especially for allergy sufferers, because the released air is even cleaner.

The advancement of technology increasingly optimizes the vacuum cleaner operation. While a lot of dust in older devices still ended up in the cleaner’s housing, this is no longer the case with the new generation models. This is ensured by the double and triple filters, which leave next to nothing.

How To Know Exactly Features Of Best Orange Juicer?

Features Of The Best Juicer

Often, we will be asked: “Which is the best juicer.” Choosing a juicer is like choosing a dress. If you go swimming, you will wear a swimsuit. If you are going to a formal occasion, you will wear a tuxedo.

Choosing a juicer is almost the same. You must match the purpose of using the juicer with the juicer itself. There are several “types” of juicers available on the market today.

Some are better suited to certain requirements and others are better suited to others. There is no “perfect” juice extractor that can complete all the juice needs and squeeze the same quality fruit and vegetable juices.

Please carefully consider your needs before buying the orange juicer. This article is based on our experience and is as accurate as possible. If you have questions, please refer to the FAQ.

Before buying a juicer, you should ask yourself which of the most important needs are you, and which period will you make such a decision. Some of the factors you should consider are.

Easy to clean Noise Speed of juicing Warranty time Types of fruits and vegetables you will squeeze.

One of the reasons why there is no “perfect” juicer is that fruits and vegetables have very different characteristics.

Some effective juice extraction methods for one type of fruit and vegetable may not be suitable for another. Fruits, which have a soft cell wall, require relatively gentle extraction methods.

Apples, pears, watermelons, melons, and pineapples are some juices that can be peeled together with the fruit. Citrus fruits, such as oranges, grapefruits, and oranges, have a bitter rind.

Juices that are squeezed out of “whole” oranges are not drinkable because of bitterness, and they also contain removable chemicals. One solution is to remove the skin (which is the only part of the skin – often leaving the white “essential” part, because the nutrients are present in the white part).

The more common method is to use the “drill” type juicer or the citrus-type squeezer juicer to squeeze all the oranges.

I often recommend that you buy organic foods as much as possible, especially fruits that are juiced on belts.

On the other hand, vegetables contain fibers, and the “stronger” cell walls require stronger mechanical extraction than fruit.

Because of the weak acidity of the vegetables, it is recommended that the vegetable juice is consumed within 15 minutes after it has been prepared because the data show that the vegetable enzyme only half the activity of the fresh vegetable juice at 30 minutes after the extraction.

When Apple or carrot juice turns dark, it shows that it is oxidized

The canned and bottled fruit and vegetable juices sold at the stores are not freshly squeezed and therefore never oxidized.

At that time, because these juices have been heat-treated, biochemical enzymes have been killed. These biochemical enzymes are the main reason for using juicers to make fresh juice and benefit from it.

I will try my best to introduce some kinds of juicers currently sold on the market in terms of working methods, advantages and disadvantages.

Centrifugal Juicer

The centrifugal juicer design is the oldest juicer design. The juicer uses a frictional cutter head or a cutting dish, and a filter basket to the side wall to collect the marc in the machine. Friction at the bottom of the basket, and is rotated at high speed (3600 rpm/min).

When the fruits and vegetables are placed on the machine, they are pushed through the feeding port and the rotating cutter head. The fruits and vegetables are shredded and the juice flows out.

The filter basket also rotates at the same high speed, just like the dehydration process of a washing machine. The powerful force pushes the juice out of the vertical side wall of the basket and collects it in front of the machine while the dregs stay inside the machine.

In general, this type of juicer is in the production of 1 – 2 quarts must be cut down after the fruits and vegetables, and slag must be removed before continuing juice. This is not a machine that can juice continuously.

The two centrifugal juicers we sell are Omega 1000 and Omega 9000. Both machines use stainless steel baskets and ball bearing induction motors. Omega 1000 has a 10-year warranty and Omega 9000 has a 15-year warranty. This juicer is suitable for most fruits and vegetables.

Parts And Functions Of Drill Machines

There are many types of drill machines, here we take a closer look at the handheld power drill.

It is a practical and versatile tool when it comes to drilling a hole in different materials. Be it wood, plastic or stone – the drill allows you to drill holes with different diameters and depths.


The externally visible part of the drill is the housing. It is usually made of plastic and is manufactured in half-shell construction.

On the housing are manufacturer information and usually a nameplate indicating the electrical power consumption, the number of revolutions, the operating voltage, and the protection class?

Many drills still have an extra handle that attaches to the housing. Such a drill is easy to hold with two hands.


The electric motor is the heart of every drill. It generates the necessary rotational movement of the drill. Most motors are operated with 220V AC voltage.


The high speed of the electric motor is not suitable for drilling, so by means of a gearbox, the high speed of the motor is translated into a lower speed of the drill.

In this case, a gear transmission is used, which is designed as a manual transmission. This makes it possible for at least 2 different gear ratios (“gears”) and sometimes even a “reverse gear”. This setting is made with the “gearshift”.


This part of the drill is an attachment that picks up the drill and allows you to work with different drills by swapping them quickly. By the chuck key, the jaws can be moved inside the chuck and the drill can be fixed or loosened again.

Drill Bits

The drill (more precisely, the drilling tool) is the insert that is picked up by the drill chuck. Through the cutting edge at the top, he penetrates into the material. There are drills for various materials – for metal, stone, wood, and plastic. The drill with a conical head.

A special type of hand drill is the impact drill. Here, the (switchable) impact mechanism in addition to the rotational movement of the drill lifting movements at high frequency. These feel like a vibration during drilling and support the drilling of materials such as concrete or stone.

What Is The Difference Between Oil-Free And Oil-Lubricated Compressor

Oil-free compressor vs. oil lubricated compressor

You are unsure whether an oil-free compressor or an oil-lubricated compressor is right for you? Depending on the requirements you place on your compressor, different models are possible.

When choosing the right device, it helps to ask yourself the following questions: Do you need a highly compressed air power, about 10 bar or 15 bar, or is a lower pressure sufficient?

Should the compressor be oil-free or is an oil-lubricated model better suited for your purposes?

Which type of compressor is more economical? Do you need the compressor as an endurance runner, that is, will it be in constant operation or is the compressor used at intervals?

In addition, the question arises as to whether the compressor is quiet must be (so-called quiet running compressors) or the sound insulation plays a minor role (e.g, when operating in a separate room).

Below you will find an overview of the advantages and disadvantages of oil-free compressors compared to oil-lubricated compressors, their applications, and quiet running compressors.

Oil-free compressors

In some purchasing decisions, the question of a comparison with the oil-lubricated air compressor is not. In certain applications, an oil-free compressor is essential or mandatory:

  • the oil-free compressor in the laboratory
  • Dental medicine
  • Spraying
  • Environmental Measurement
  • Food u. beverage industry
  • pharmaceutical industry
  • chemical industry
  • Electrical engineering

In addition, best quiet air compressor is more and more oil-free compressors are also used in areas where an oil-lubricated compressor could also be used. The main reasons for this are the low environmental impact and the minimal maintenance effort. The Airwin oil-free compressors we offer also have the advantage of being particularly quiet.

 Advantages and Disadvantages At A Glance

Oil-Free Compressor Advantages

  • minimal maintenance
  • clean, oil-free compressed air
  • no oil change / oil separation required
  • no oil filter replacement necessary
  • especially environmentally friendly
  • Treatment and disposal costs are eliminated

Oil Free Compressor Disadvantages

  • limited operating pressure up to 8 bar
  • high investment costs for equipment with a relatively high intake volume.

Oil Lubricated Compressors Advantages

  • higher operating pressure possible
  • simultaneous lubrication (eg important for compressed air tools)
  • long lifetime

Oil Lubricated Compressors Disadvantages

  • higher maintenance costs
  • Oil change & disposal of used oil required
  • Oil leaks can occur
  • Air / environmental pollution


An oil-free air compressor offers many advantages. The lower maintenance costs are not only reflected in the lack of purchase cost of compressor oil and air filter, but also include the amount of time an employee or a maintenance service has to do.

Oil level controls are eliminated, there is no hazardous waste (waste oil), and you can also save oil filter and oil separator.

For certain areas (see above), a compressed air compressor that operates without oil is also essential.

The compressed air containing trace amounts of oil can not be used in sensitive areas, e.g, in the production of food, medical and hygiene articles, in the laboratory and in research, or in the processing of paints and varnishes.

Oil-free compressors are  well-suited for

  • Paint processing,
  • Blowing with clean compressed air,
  • For airbrushing,
  • In the production and processing of food and beverages,
  • In laboratories,
  • In dentistry or dental technicians / dental laboratories,
  • In the dust removal,
  • In the field of production of electronic parts
  • In the pharmaceutical or chemical industry,
  • To prevent contamination with oil.

Another advantage is the lower volume of oil-free Air Win compressors over ordinary reciprocating compressors.

The oil lubricated compressor then the better choice if the required compressed air, or the speed could only be achieved with very expensive oil-free compressors and the oil for the lubrication of e.g, pneumatic tools is advantageous.

In addition, when investing in your compressed air system, remember that an oil lubricated compressor has a longer service life than a device without oil.
