Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of protective equipment, it is recommended to prioritize checking key technical parameters such as protection level and pressure resistance range to ensure compatibility with equipment or environmental requirements.
  • In industrial dust or chemical corrosion scenarios, the material selection of protective equipment should be based on specific working conditions, such as stainless steel shells being more suitable for high corrosion environments.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support to reduce procurement risks.
  • Different application scenarios may have differentiated requirements for the sealing performance of protective devices, such as outdoor equipment requiring attention to waterproof performance, while high-temperature workshops require emphasis on heat resistance indicators.
