Purchasing Guide

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

  • For procurement requirements that require the use of air ducts, it is recommended to prioritize confirming key technical parameters such as duct material, pressure rating, and interface size to ensure compatibility with existing systems.
  • In industrial ventilation or clean room scenarios, the application of air ducts needs to consider air volume adaptability, and there are differences in the requirements for pipe diameter and bending radius in different scenarios.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information.
  • When purchasing ducts, attention should be paid to whether the supplier provides multiple specification options to meet the requirements of duct system renovation in different environments such as commercial buildings and factories.
