What is the normal air?

Analysis of Environmental Protection Standards for Air Compressors: Guidelines for Compliance and Green Development air compressor environmental standards focus energy efficiency, noise, emissions and resource recycling, mainly covers the following requirements: energy Efficiency Standards european Union: The ERP directive requires air compressor energy efficiency ratio (EER)≥ 7.0 (from 2021) to promote the popularization of IE4 […]

The oil content standards of oil-free air compressors vary depending on different application scenarios. The following is a detailed explanation: 1. International standard: ISO 8573-1 This standard divides the oil content in compressed air into levels 0-5, of which: Level 0:…

Ventilators usually use both oxygen and compressed air as air sources. Specifically: Oxygen: Effect: Provide the oxygen needed by the patient to maintain normal blood oxygen saturation. Pressure regulation: The working pressure of oxygen is usually adjusted to 0.4MPa (equivalent to 4 atmospheres of pressure), ensuring that the ventilator can provide a stable and sufficient […]

The oil content testing standards for industrial compressed air vary depending on the application field and industry. The following are the specific standards and testing methods: 1. The core testing standard ISO 8573 International Standard Class 0 (highest level): Total oil content…

There are many differences between frequency conversion screw air compressors and non-frequency conversion screw air compressors, which are mainly reflected in the following aspects: Working principle Frequency conversion screw air compressors: Change the power supply frequency of the motor through the frequency converter, thereby adjusting the speed of the motor, and then make air…
