How is compressed air flow rate calculated?
This article provides a detailed explanation of the definition of compressed air flow rate (CFM), its core calculation methods—namely, the state‑conversion method, the demand‑summation method, and the velocity‑inversion method—as well as the factors that influence it. It also…
Is a mobile air compressor a pressure vessel?
Mobile air compressors as complete units are not classified as special equipment; however, if their accompanying pressure vessels have a volume of ≥25 L and a working pressure of ≥0.1 MPa, they qualify as pressure vessels under the…
What is the vibration value range for the air compressor main unit?
The vibration level of an air compressor’s main unit is typically assessed according to the ISO 20816 standard. Under normal operating conditions, it should generally be ≤2.8 mm/s (RMS); values exceeding 4.5 mm/s warrant close attention, and readings…
Scrapping Standards for Air Compressor Air Tanks
The decommissioning of air compressor pressure vessels shall be carried out in accordance with TSG 21; the principal circumstances include exceeding the service life, failing inspection, and the presence of irreparable defects. Periodic inspections serve as the key…
Moisture Content Standards for Compressed Air in the Pharmaceutical Industry
The moisture content of pharmaceutical compressed air directly affects sterility assurance and product quality. This article analyzes the classification requirements for pressure dew point specified in ISO 8573‑1, and, in conjunction with GMP’s control framework for clean compressed…
What is the water content at a dew point of −34°C?
At standard atmospheric pressure, a dew point of −34°C corresponds to a moisture content of approximately 0.29 g/m³ (per dry air), or 156 ppmᵥ. This dew‑point level is suitable for high‑requirement industrial applications and is typically achieved using…
Air Compressor Energy-Saving Retrofit Plan: A 2026 Guide for Corporate Cost Reduction and Efficiency Enhancement
In most factories, electricity costs for compressed‑air systems account for20% ～ 35%of total energy consumption, yet the actual compression efficiency of conventional units often falls short of 70%—with substantial electrical energy wasted through unloading, leaks, and excess pressure.…
Qinghai Oil-Free Screw Compressors: A Clean Compressed Air Solution for High-Altitude Industrial Applications
The high-altitude, low-oxygen, and wide-temperature‑range environment of Qinghai poses unique challenges to air compressors. Oil-free screw compressors, with their zero oil contamination, high purity, and robust environmental adaptability, have become the ideal choice for industries such as food,…
