The respirator is one of the most demanded personal respiratory protection equipment. The device is quite simple, but it is quite capable of preventing the penetration of particles of polluted air into the organs of the human bronchopulmonary system. In Russia, the models of the 3M company are in great demand - they will be discussed in our review.

general description

Long ago, our grandparents noted that people working in dusty places sooner or later acquire serious pathologies of the respiratory system. Even our ancient ancestors created primitive dust protection products . Previously, their role was played by cloth bandages, which were moistened with water from time to time. In this way, the air entering the lungs was filtered. Anyone can quickly and easily make such a mask, if necessary, saving human life in an emergency.

However, a wet bandage is a necessary measure. Models of respirators are widespread these days, moreover, they have become mandatory for workers in some industries.

The 3M company has become one of the leaders in the segment of satellites production . The company's respirators are a practical design designed to maintain the safe performance of jobs involving high levels of contamination and emission of harmful gases.

Users appreciate 3M devices for their simplicity of design. There are disposable and reusable models on the market. The first ones are characterized by simplicity of design - their base is a half mask made of polymers, which also serves as a filter.

Products with replaceable filters have a complicated design; they represent a full-face mask made of rubber or plastic. They have exhalation valves, and there are 2 filters on the sides.

Advantages and disadvantages

All satellites manufactured by 3M are manufactured at modern production facilities equipped with the most high-tech equipment. Special attention is paid by the company's engineers to close control of the quality of manufactured products - that is why respirators of this brand meet the most stringent international standards.

The main goal of 3M is to establish production of products that are guaranteed to fulfill the main goal - to protect a person and his health from adverse external influences . In addition, the manufacturer made sure that the protective equipment was as comfortable to wear as possible - this is a significant plus, given that the activities of many users are associated with the constant wearing of these devices.

Modern versions of 3M respirators are made of multi-layered high-tech fabric, which provides the most effective filtration of inhaled air. Such devices provide an increased degree of reliability, since each layer forms its own separate degree of protection against dust ., organic impurities, liquid aerosols, gases and other pollutants. An important bonus is that all 3M respirator models are compact and lightweight, so they can be worn without discomfort. For maximum hold, they are complemented with high-quality rubber bands.

3M respirators do not lose their technical and operational characteristics at a wide variety of temperature levels - they can be used both in cold weather and in heat. All manufactured respirators comply with international quality standards ISO 9000, as well as Russian GOST.

However, a 3M respirator is not a panacea. In a particularly toxic environment, wearing it is ineffective. In the event of a dangerous situation, only a gas mask is able to fully protect the mucous membrane, the organs of vision and respiration.

Applications

Protective masks of the ZM brand, depending on the scope, can be conditionally divided into 3 categories.

Respirator for neutralization of aerosols and dust particles

It is known that dust and aerosol particles range in size from a few microns to a millimeter and even more, which is why they can be removed using conventional filtration. Dust masks contain filters made from man-made materials composed of many fine fibers - it can be polyester fiber, perchlorovinyl or polyurethane foam.

In most cases, dust filters carry a certain amount of electrostatic charge ., an attracting pollutant that improves the overall efficiency of air purification. We pay special attention to the fact that an anti-dust respirator is able to provide high-quality protection against dust, as well as smoke and spray nozzles. At the same time, it will not save a person from vapors and gases, and will not retain unpleasant odors.

In addition, such models are absolutely ineffective in places of biological, chemical, and radiation damage.

Gas respirators

Gas masks protect the user from possible gases as well as harmful vapors, including mercury, acetone, gasoline and chlorine. Such devices are in demand when carrying out painting and painting works . Vapors and gases are not particles, but full-fledged molecules, therefore it is simply impossible to keep them in any way through fibrous filters. The effectiveness of their action is based on the use of sorbents and catalysts.

It should be noted that gas filters are by no means universal … The fact is that different gases have different physical and chemical properties; therefore, the same catalyst or carbon sorbent cannot provide the same efficiency. That is why stores have an impressive selection of gas filters used to protect against certain gases and certain categories of chemicals.

Respirators for all types of air pollution

These are called gas and dust protection (combined) means of protection. Their filter includes both fibrous materials and sorbents in its structure. As a result, they are able to provide maximum protection from aerosols, dust and volatile gases at the same time. The scope of application of such models is as wide as possible - they are used in all spheres of industry, including nuclear power.

Model overview

3M offers a wide selection of a wide variety of respirators, which may differ in design features, contamination categories and some other parameters. Depending on the features of the model, there are:

• models with built-in filter;
• models with removable filters.

Devices of the first type are extremely easy to use, which is why they have a budget price, but have a limited period of operation. For the most part, they are classified as disposable. The second group of respirators has a slightly more complex design, therefore, its cost is an order of magnitude higher.

At the same time, the respirator is characterized by durability, and the filters in them are simply changed if necessary.

3M respirators are available in three versions

Quarter mask - a petal model covering the mouth and nose, but the chin remains open. This model is practically not used, since it does not provide reliable protection, and is inconvenient in operation.

Half mask - the most common version of respirators, covers only half of the face from the nose to the chin. This model provides reliable protection against adverse environmental factors and comfort of use.

Full face mask - this model completely covers the face, creating additional protection for the organs of vision. Such devices are classified as expensive, but they also provide the highest protection.

3M respirators are classified according to the nature of their protection:

• filtering;
• with forced air supply.

In devices of the first type, polluted air is cleaned in a filter, but it enters directly into them due to breathing, that is, "by gravity". Such models are used in everyday life. In devices of the second category, already purified air is supplied from a cylinder. Such respirators are relevant in the conditions of industrial workshops, they are also in demand among rescuers.

The most popular 3M respirator models include

Media models (8101, 8102) . Used to protect respiratory organs from aerosol particles. They are made in the form of a bowl. Complemented with elastic bands for maximum hold around the head, as well as foam nose clips. The surface has anti-corrosion and abrasion resistance. Such respirators have found their use in agriculture, as well as construction, metalworking and woodworking.

Model 9300 . These respirators are designed as anti-aerosols and are used at the enterprises of the nuclear industry. They are advanced products that are designed to communicate seamlessly.

Respirator ZM 111R is another popular dust mask that can help you breathe easier. It is distinguished by its compact size and ergonomic design.

In addition to an efficient filtration system, many models are equipped with a blow-out valve.

Selection rules

When choosing the optimal 3M model, several key parameters need to be taken into account:

• the expected intensity and regularity of respirator use;
• category of polluting elements;
• Terms of Use;
• concentration level of hazardous substances.

So, if you need the device a couple of times during repair or painting, then you can use the simplest one-time version with a built-in filter. But for painters, plasterers or welders, you should choose reusable respirators with replaceable double filters. To maintain their full performance, you only need to periodically purchase new replacement filters.

It is important to take into account what types of pollutants the respirator will have to protect you from, based on this, they acquire a specific type of respirator. Any mistake is dangerous to health.

The operating conditions should be taken into account. So, if your activity does not involve any loads and active movements, then you can use the dimensional model with forced air supply . If in the course of performing your work duties you have to move a lot, then preference should be given to lightweight models that will not interfere and cause discomfort.

It is imperative to get the right size . Remember - the device should fit quite tightly to the face to prevent the ingress of unfiltered air. But it is also impossible to allow excessive compression of soft tissues.

There are a few steps to follow before buying

• Take measurements of your face - you will need a length from the chin to the indentation on the bridge of the nose. 3M respirators are available in three sizes:

  • for face height less than 109 mm;
  • 110 120 mm;
  • 121 mm or more.
• Before purchasing, remove the product from its individual packaging and inspect for damage and defects.
• Try on a mask, it should reliably cover your mouth and nose.
• Check the tightness of the accessory. To do this, cover the ventilation holes with your palm and take a shallow breath. If at the same time you feel the flow of air, it is better to choose another model.

In conclusion, we note that the most reliable respirator is a high quality respirator from the manufacturer. Unfortunately, the household goods market these days is overflowing with counterfeits, while their low cost fully corresponds to the quality.

Each expert will recommend purchasing personal protective equipment from certified manufacturers. Remember! You shouldn't save on your health.
