A medical air compressor is a piece of equipment specifically designed for use in the medical field to provide clean, compressed air to supply medical equipment and operations. It is commonly used in hospitals, clinics, emergency centers, and other medical facilities.

Medical air compressors have the following features and functions:

High cleanliness requirements: medical air compressors need to be able to provide clean air to ensure the health and safety of patients. Therefore, they are often fitted with filters and other clean equipment to remove particles and impurities from the air.

Stable Output Pressure: Medical equipment has very strict requirements on air supply, so medical air compressors need to be able to provide the required compressed air stably to ensure the normal operation of medical equipment.

Compliance with medical standards: Medical air compressors need to comply with the relevant standards and regulations of the medical industry to ensure their safety and reliability in the medical environment.

Well-designed: Medical air compressors are usually designed to be compact and quiet, making them easy to install and operate in medical facilities.

Overall, medical air compressors are an indispensable piece of equipment in medical facilities. They provide a critical supply of compressed air for medical equipment and surgeries, ensuring the smooth running of medical operations and the health and safety of patients.

The working principle of a medical air compressor usually includes the following steps:

Suction: The medical air compressor introduces outside air into the interior of the machine through a suction system.

Filtration: The introduced external air passes through a series of filtration systems to remove fine dust, bacteria and other impurities to ensure the cleanliness of the air.

Compression: The filtered air enters the compression chamber, where a piston or rotary mechanism compresses the air and increases its pressure.

Storage: The compressed air is stored in a tank or storage system in case it is needed for medical equipment and surgery.

Supply: When compressed air is needed for medical equipment or surgery, the air is released and supplied to the equipment or operation that needs it.

Medical air compressors are usually equipped with a series of sensors and controllers during operation to monitor and regulate parameters such as air pressure, temperature and cleanliness to ensure that the air supplied meets medical standards and requirements.

These steps and systems are designed to enable medical air compressors to provide a stable and reliable supply of clean compressed air to medical equipment and surgical operations, ensuring the safety and smooth running of medical services.

There are many kinds of air compressors, according to its working principle, such as volumetric type, power type, etc., commonly used in hospitals are mainly volumetric compressors.
Air compressors commonly used in hospitals are mainly volumetric compressors. Common types of volumetric compressors are oil (oil-free) piston compressors, screw compressors, oil-injected sliding vane air compressors, oil-free rotary tooth air compressors, and oil-free scroll air compressors.

In the process of purchasing air compressors, the two most important parameters are one is the amount of air and the other is the air pressure, the air pressure is relatively easy to determine. But the demand for air consumption will be more difficult to calculate accurately, especially when there are more air ports and many times there is a difference in the amount of air used at various times of the day. If you are not sure of the exact amount of gas you need, you can consult Amcaremed and let our professional engineers do the calculation.

Steps to determine air consumption
Firstly, determine the amount of air required for each air-using equipment to run continuously without interruption. The air consumption of each piece of equipment can be provided by the manufacturer, but not the sum of the total air consumption of these devices as the basis for the total air compressor station. This may cause the air compressor equipment selection is too large to cause unnecessary waste.

Understand the length of time each air-using equipment, in addition to transporting gas and other continuous air-using equipment, most of the air-using equipment generally do not continue to use gas. So you should take an average of the time of use as a factor or determine a percentage. Generally the average time of gas use is then between 20 and 60%.

Determine the simultaneity coefficient, because not all gas-using equipment uses gas at the same time. The coefficient of simultaneity is determined because not all equipment uses air at the same time, and it is a value accumulated during the process of using air by more than one air-using equipment.

Compressed air demand
The continuous air consumption of each air-using equipment and tool is multiplied by the corresponding air consumption time coefficient and simultaneity coefficient, and this value can be used as the average air consumption of each air-using equipment in the air-using network.

Points to note
The gas consumption of each gas-using equipment is for new machines, and the gas consumption will increase by 5% to 10% with the increase of the usage time.
Pay attention to gas line leakage, which is difficult to avoid but needs to be checked regularly. Generally 5% of gas leakage will be taken into account.
It is necessary to determine the pressure of gas consumption with the equipment manufacturer.
Determine whether it is necessary to increase the gas consumption or add gas equipment at a later stage.

Atmospheric pressure has a great impact on the performance of air compressors. Changes in atmospheric pressure directly affect the amount of exhaust volume, which should be noted. This can be understood in this way: the atmospheric pressure is actually the mass of the air column per unit area from the ground to the top of the atmosphere. It can be seen that if the plateau area, the air column is naturally shorter, the density of the air is also smaller, the atmospheric pressure is also lower. The air compressor is usually directly inhaled into the atmosphere, if in the plateau area, compared with the plains near the sea level, because the density of the air is small, the air inhaled is also less, the amount of air discharged will naturally become less.

Regarding altitude, because the earth itself is not really round, the average altitude refers to the average of multiple mapping points around the world, for general reference only. Regarding atmospheric pressure, in addition to the altitude factor, it is also related to temperature and humidity, so the atmospheric pressure is higher in the dry winter season and lower in the rainy summer. Of course, the influence of these factors on the atmospheric pressure is not large, within 3%.

Effect of altitude on air compressor.
The higher the altitude, the thinner the air, the lower the atmospheric pressure, the higher the compression ratio;

The higher the altitude, the worse the cooling effect (air-cooled), which can cause the motor temperature rise is too high;

The higher the altitude, the lower the volumetric flow rate of the compressor at the same speed.
