Which industries need to use compressed air at a pressure of 5 kilograms
Application industry of compressed air with pressure of 5 kg
industry background
Compressed air with a pressure of 5kg (0.5MPa) is an important source of power in the industrial field and is widely used in scenarios that require high pressure stability but do not require ultra-high pressure. This pressure range not only meets the power needs of most pneumatic equipment, but also balances energy consumption with equipment life. According to the compressed air purity rating standard ISO 8573-1:2010, industries using a pressure of 5 kilograms need to also pay attention to the following parameters:
- Oil content: <0.01ppm
- Dust content: <0.01μm
- Dew point: ≤-20℃ (PDP)
Shanghai Granklin Group’s industrial oil-free air compressors have passed Germany’s Tüv “0” oil-free certification, providing clean air solutions suitable for 5 kg pressure for multiple industries.
Why do these industries need 5kg of pressure?
- food packaging industry
- application scenarios: Pneumatic sealing machines, filling equipment, labeling machines
- pressure demand: 0.5-0.7MPa (sealing strength>50N/cm²)
- cleaning requirements: It is necessary to meet the compressed air standard for food production (oil content <0.01ppm) to avoid grease contaminating the packaging contents.
- textile industry
- application scenarios: Air-jet loom, yarn shaping, pneumatic winding
- pressure demand: 0.4-0.6MPa (loom nozzle air flow speed ≥200m/s)
- energy consumption optimization: Permanent magnet frequency conversion technology reduces energy consumption by 15% and passes ISO 50001 certification.
- Electronic component manufacturing
- application scenarios: PCB cleaning, chip packaging, static elimination
- pressure demand: 0.5±0.05MPa (pressure fluctuations cause a 3% decrease in yield)
- certification requirements: Comply with semiconductor manufacturing gas standards (dust content 0.01μm).
- glass article processing
- application scenarios: Glass cutting, mold cooling, pneumatic handling
- pressure demand: 0.6-0.8MPa (cutting accuracy error <0.1mm)
- risk control: Residual oil will cause atomization on the glass surface (scrapping rate +8%).
Selection of core parameters
According to ISO 8573-1:2010 and industry specifications, the following parameters need to be verified:
| parameters | standard requirements | Certification support |
|---|---|---|
| pressure stability | ≤ 0.5% FS (0.5MPa benchmark) | Germany Tüv “0” oil-free certification |
| instantaneous flow | ≥150% rated flow (peak demand) | quality management system certification |
| dew point control | -20℃（PDP）±3℃ | environmental management system certification |
| oil content | <0.01ppm (online monitoring) | Product quality and safety certification certificate |
Potential risks of not using oil-free air compressors
- Food packaging leaks: Insufficient pressure leads to a decrease in sealing strength (leakage rate +5%) and causes product deterioration (a single batch loss exceeds 300,000 yuan).
- Textile efficiency declines: A fluctuation in air pressure of an air-jet loom of>1% will cause the weft break rate to increase to 3%(a loss of 2 million meters in annual output).
- Electronic component scrap: Unstable PCB cleaning air pressure causes electrostatic breakdown (yield drops to 92%).
- Waste of energy consumption: For every 0.1MPa pressure excess, annual power consumption increases by 8%(calculated on a 100kW model, a waste of more than 100,000 yuan).
Economic benefits of using oil-free air compressors
| Income dimension | quantitative indicators | Certification support |
|---|---|---|
| Improved sealing pass rate | Leakage rate dropped from 0.5% to 0.08% | quality management system certification |
| Loom efficiency optimization | Broken weft rate dropped from 3% to 0.8% | Product quality and safety certification certificate |
| Improved chip packaging yield | Yield +4% | environmental management system certification |
| comprehensive energy consumption | The 100kW model saves 180,000 yuan in annual electricity bills | ISO 50001 energy management system |
Comparison of oilless compressor versus oilless compressor in a 5kg pressure scenario
| parameters | oil-free compressor | Oiled compressor |
|---|---|---|
| oil content | <0.01ppm（Class 1） | ≥0.05ppm (secondary filtration required) |
| pressure fluctuations | ±0.3%FS (PID control) | ± 1.2% FS (mechanical adjustment) |
| unit energy consumption | 0.15kW/m³ | 0.21kW/m³ |
| Average annual maintenance cost | 80,000 – 120,000 yuan | 200,000 – 300,000 yuan (oil-containing filter replacement) |
summary
The demand for 5 kilograms of pressurized compressed air in food packaging, textile manufacturing, electronic processing and other industries is not only related to production efficiency, but also directly affects product quality and compliance. By adopting oil-free air compressors that comply with ISO 8573-1:2010 Class 1 standards, companies can simultaneously achieve precise pressure control, energy consumption cost optimization, and zero pollution risks. The industrial-grade oil-free compression technology provided by Shanghai Granklin Group provides cost-effective solutions for multiple industries to adapt to a pressure of 5 kg.
