Aseptic production gas requirements and water lubricated single screw air compressor suitability analysis
the production of aseptic products has extremely strict requirements on the quality of compressed air. Its core is to ensure that the compressed air is oil-free, sterile and dust-free, so as to avoid pollution to the production environment and products. The following analysis is carried out from three aspects: gas standard, technical adaptability and equipment advantages:
Cleanliness requirements
The production environment of sterile products usually needs to meet ISO 5 (100) or higher cleanliness standards, that is, the number of particles ≥ 0.5 microns per cubic meter of air does not exceed 3520. As a process gas, the cleanliness of compressed air should be matched with the production environment to avoid the introduction of particulate pollution. For example, the pharmaceutical industry requires compressed air dust content ≤ 3.5 particles/L(>0.5 μm) and microbial count <1 CFU/m & sup3;.
Sterility requirements
The compressed air must pass through a high-efficiency filtration system (such as HEPA/ULPA filters) to remove bacteria, viruses and other microorganisms to ensure sterility. The international standard ISO 8573 series stipulates that the microbial limit of compressed air for pharmaceutical use shall be <1 CFU/m & sup3;.
Oil-free requirements
Lubricating oil is one of the main sources of compressed air pollution. Oil may adhere to the surface of the product or enter the production system, resulting in product quality degradation or even safety hazards. Therefore, the production of aseptic products requires the use of oil-free compressed air.
Oil-free compression technology
The water-lubricated single-screw air compressor uses water as the lubricating medium, and compresses through the meshing of the single screw and the star wheel. The water film replaces the traditional lubricating oil, completely eliminates the risk of oil pollution and ensures that the compressed air is oil-free.
Efficient filtration and cleanliness guarantee
The technology reduces wear of metal parts and particle generation through water film sealing. At the same time, the compressed air needs to be further purified by multi-stage filtration (such as primary, medium and high efficiency filters) to meet the cleanliness requirements of sterile products.
Stability and reliability
The water lubricated single screw air compressor has simple structure, stable operation and low failure rate. Its internal structure is optimized and high-quality materials are used to ensure long-term stable operation, reduce the risk of downtime and ensure production continuity.
the oil-free compressed air output from the water-lubricated single-screw air compressor in line with industry standards
can meet the strict requirements of pharmaceutical, medical equipment, food and other industries for process gas. For example, in the production of sterile medical devices, compressed air needs to be used for air tightness testing, cleaning and drying, and oil-free characteristics can avoid product contamination.
Reduce maintenance costs
The water lubrication system eliminates the need for oil circuit maintenance, oil replacement and other links, and only requires regular replacement of the water filter, which significantly reduces maintenance costs. At the same time, the life of the equipment is extended, further reducing long-term investment.
Environmental protection and energy
-saving water lubrication technology no oil emissions, in line with environmental requirements. In addition, the equipment achieves efficient compression through optimized design and low energy consumption, which helps companies reduce operating costs.
the requirements for compressed air in the production of aseptic products focus on the three core indicators of oil-free, sterile and dust-free. Water lubricated single screw air compressor through water film lubrication technology, completely eliminate the risk of oil pollution, with multi-stage filtration system, can provide stable clean compressed air in line with industry standards. Its simple structure, stable operation and low maintenance cost make it an ideal choice for the production of sterile products.
The calculation of the air consumption of the equipment involves many factors, and the specific method can be determined according to the type of equipment, the use scenario and the quality of the required compressed air. The following are some common calculation methods and steps: 1. traditional calculation methods for new plants or new items.
Air compressor (air compressor) is a device that converts mechanical energy into compressed air kinetic energy, and its work scene covers a wide range of fields such as industry, medical treatment, energy, and transportation. The following are typical application scenarios and technical details: 1. Pneumatic workers in manufacturing and industrial production lines
To determine the required air compressor flow, need to combine the following key factors analysis: 1. core calculation formula According to the derivation of the ideal gas state equation, the required air compressor flow rate calculation formula is: Q = tV×(P2 & minus;P1 )× 1.1 where: q: air compressor
Whether the air compressor room needs to focus on seepage control depends on many factors, but in general, seepage control measures are necessary. The air compressor room is usually equipped with air compressors and related equipment, which may produce vibration, noise and certain liquid seepage during operation.
When discussing which is more economical for an air compressor without oil or oil, we need to consider multiple factors, including procurement costs, operating costs, maintenance costs, and environmental impact. The following is a detailed analysis of the economics of oil-free and oil-free air compressors: mining
Hospital air compressors play a vital role in the medical field. It is one of the main components of the medical air system and is specifically designed to meet the various needs of the hospital's specific environment. The following is a rigorous description of the hospital air compressor: 1. definition and type of hospital air pressure
The compressed air used in the field of medical devices is directly related to patient safety and product quality, and its detection should strictly follow the special standards of the medical industry. Now on the test items, technical requirements and implementation of the specification for professional description
The carbon deposition cleaning cycle of the screw air compressor is not static, but is affected by many factors, including the use environment of the air compressor, the operating time, the load condition and the maintenance strategy. Therefore, an exact cleaning time interval cannot be given. General
In the field of chemical industry, the role of air compressor is very important. Shanghai Granklin Group's water-lubricated screw air compressor is favored in the industry with its unique advantages. Chemical production requires a variety of gases, and the transportation of these gases depends on the air compressor. Granklin
There is a close relationship between workshop gas consumption and gas supply. Simply put, the gas supply should meet the gas demand of the workshop, taking into account efficiency and cost. First of all, the workshop gas consumption refers to the amount of gas actually used by the workshop in the production process. This
