Respirator Guide

Under one Respirator , which is also referred to as a gas mask or breathing mask, is understood to mean a breathing connection which protects the wearer of the mask from poisons in the air. Today, respirators are mainly made of silicone or rubber. Previously, the copies were made of fabric and leather.

Development of respirators
Nikolai Dmitrievich Selinski first developed a 1915 one Respirator , which was equipped with a carbon filter and was mainly used in mining. Both the First and the Second World War played a decisive role in the further development of respirators. While the masks were still made of impregnated fabric at the beginning of the First World War and had only cotton filters, models of chemical-absorbent materials were developed in the ensuing period. Soldiers of all warring parties used them to protect against chemical warfare agents. Even for horses special protective masks were created. Even before the beginning of the Second World War, protective masks for the civilian population were finally developed, which were known as Volksgasmasken. Special masks for children were also developed at that time.

Self-contained and circulating air-dependent respirators
There are both self-contained breathing masks and air-circulating models. Ventilation-independent masks have a SCBA system, which consists of a breathing connection and a device for supplying clean breathing gas. Recirculation-dependent models have a breathing connection and a respiratory filter, which is either attached directly to the mask, or connected by a hose with her.

full face mask
Full masks surround the face on forehead, chin and cheeks and are composed of a mask body made of rubber or silicone, one or two lenses, which are located in a sealing frame, an exhalation valve, a shoulder strap, a harness and an inner mask or air ducts together. Breathing air enters the inner mask via control valves and prevents fogging of the visor. Owns the Respirator no inner mask, so air ducts are installed. Furthermore, full-throttle masks have a speech membrane and a connector to which a regulator or respiratory filter is attached.

half mask
Half masks, as well as quarter masks, cover only the mouth and nose, but not the eye region. In principle, they resemble in their construction the full masks, the half masks are equipped with neither lens nor inner mask. They are mainly used as protection against dust, silo as well as mining.

Respirator with regulator
As soon as the wearer of the mask begins to breathe, a negative pressure is created in the mask. The regulator then causes air to enter the mask body through the inhalation valve. The control valves, which are located on the inner mask, forward the air to those from where it enters the lungs of the wearer. When exhaling, the inhalation valve closes and the exhaled air passes through the exhalation valve to the outside.

Respiratory mask with respiratory protection filter
For respirators with a respirator, the wearer of the mask must overcome inhalation resistance when inhaling. For this reason, shallow breathing can cause the level of carbon dioxide in the mask to increase and eventually lead to the wearer losing consciousness.

Normal pressure mask
In normal pressure masks, a regulator ensures that the negative pressure in the mask resulting from inhalation is immediately compensated. The pressure conditions in the interior of the mask are thus identical to those of the environment, so that even with a leak of the mask no major loss of air threatens. However, there is danger to the wearer if the mask is not completely tight and in the short phase of negative pressure, toxins from the environment penetrate into the mask.

Pressure mask
In the case of overpressure masks, the regulator generates an overpressure in the mask, which makes it easier for the wearer to inhale. If the mask is leaking, toxins can not get into the mask body. In the event of a leak, however, the delivery of the exhaled air is made more difficult, which is why overpressure masks offer a certain risk potential in this case.

Purchase of respirators
On the online platform „Amazon“ there are many different models of respirators. For example, the masks „3M half mask 4255, FFA2P3RD, against organic gases and vapors and particles“ and „3M 6002C reusable half mask with replacement filters for paint spraying and machine sanding, protection level A2P2“ by 3M as well as the full face mask „Dräger X -plore 6300 Full face mask with threaded connection according to DIN EN 148-1 „by Dräger.
