Features of industrial Flex vacuum cleaners

The industrial vacuum cleaner is designed for cleaning industrial, construction and agricultural sites. Its main difference from its household counterpart is the nature of the garbage to be absorbed. If a household appliance disposes of dust and small debris, then an industrial appliance handles all sorts of materials. These can be sawdust, oil, sand, cement, steel shavings, and more.

Industrial vacuum cleaners have a high working power, are equipped with a vacuum system to absorb dissimilar debris. They have a high-quality filtration system, as well as a container for collecting garbage of impressive size. Many companies are engaged in the production of such equipment. One of these is Flex.

The German brand Flex started in 1922 with the invention of grinding tools. It is renowned for manufacturing hand-held grinders as well as angle grinders. The widely used concept of flexing originates from the name of this particular company.

Until 1996, it was called Ackermann + Schmitt after its founders. And in 1996 it was renamed Flex, which means “flexible” in German.

One of the main indicators of an electrical appliance is the engine and its power. It is on him that the efficiency and quality of the technology depends. For industrial vacuum cleaners, this figure varies from 1 to 50 kW.

Flex industrial vacuum cleaners have a capacity of up to 1.4 kW. Their low weight (up to 18 kg) and compact size allow them to be used:

• on construction sites when working with wood, paint and varnish coatings, when repairing roofs, walls with insulation in the form of mineral wool;
• when cleaning offices and warehouses;
• for cleaning car interiors;
• when working with small electrical appliances.

The low power of the machine is not intended for large enterprises with a large amount of bulky waste, but it copes perfectly with cleaning in small rooms, moreover, it is easy to transport due to its compact size.

In turn, the power depends on 2 values: vacuum and air flow. The vacuum is generated by a vacuum turbine and characterizes the machine's ability to suck up heavy particles. The limiting indicator in this case is 60 kPa. For Flex brand vacuum cleaners it is up to 25 kPa. In addition, the turbine is placed in a capsule, which allows the device to operate almost silently.

The air flow ensures that the light elements are sucked in and passed through the suction hose. Flex machines are equipped with a sensor system that controls the volume of incoming air. When its indicators decrease below the minimum permissible value (20 m / s), a sound and light signal appears. In addition, the devices of some models have a switch for regulating the incoming air flow.

The motor of industrial vacuum cleaners of the presented brand is single-phase, operates on a 220 V network. It is equipped with a bypass air injection system. Thanks to it, the intake air flow and the air cooling the motor are blown through separate channels, which protects against contaminated intake air from entering it, increases the operating power and prolongs the service life of the device.

The engine starts with a slow start.This feature ensures that there are no voltage drops at the beginning of the process. At the end of the work, the delay system is activated after shutdown, in which the vacuum cleaner continues its activity inertially for another 15 seconds. This allows the remaining dust particles to be removed from the hose.

The body of industrial vacuum cleaners of this brand is presented by shockproof recyclable plastic. It is lightweight and durable at the same time, does not corrode, and is easy to clean. On the body there is a holder for a hose and a cord, which has a length of up to 8 m.

The vacuum cleaner has a socket for connecting electrical appliances with a power of 100 to 2400 W. When the appliance is plugged into an outlet, the vacuum cleaner turns on automatically. When you turn it off, the machine turns off automatically. This feature allows you to remove debris during work, preventing it from spreading in space. At the bottom of the body there are 2 main wheels for easy movement and additional rollers with a brake.

Industrial vacuum cleaners of the described brand are designed for dry and wet cleaning. This allows them to handle not only dry debris, but also water, oil and other liquids.

As for the dust collector, it is universal. That is, it can work with or without a bag. The container for collecting dust, depending on the model of the machine, has a volume of up to 40 liters. It is convenient for picking up large, wet debris and water. A trash bag is provided with the appliance. It is made of heavy-duty material that does not break when in contact with sharp objects.

In addition to the dust collector, Flex machines have an additional filter. Due to the flat and folded structure, it is tightly and motionlessly installed in the compartment, does not undergo deformation, displacement, and even during wet cleaning it remains dry.

Some models are equipped with a hera filter. It is capable of capturing microparticles of 1 micron in size. They are used in pharmaceuticals and other industries where fine-caliber dust is formed. These filters are reusable and must be thoroughly cleaned, since the performance of the machine and the load on the engine depend on the passability of this part.

Cleaning can be done in 2 ways: manual or automatic. It depends on the type of device. Automatic cleaning can be performed without interrupting its operation. These vacuum cleaners cope with 3 classes of pollution.

• Class L - dust with a low degree of hazard. This category includes construction waste with dust particles exceeding 1 mg / m³.

• Class M - waste with a medium degree of danger: concrete, plaster, masonry dust, wood waste.

• Class H - waste with a high degree of danger: carcinogens, fungi and other pathogens, atomic dust.
