Purchasing Guide

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

  • For procurement requirements that require the use of inorganic fiberglass ducts, it is recommended to prioritize confirming key technical parameters such as wall thickness, temperature resistance range, and compressive strength of the ducts to ensure their suitability for corrosive environments or special scenarios such as chemical and underground engineering.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support or platform statistical information. Such suppliers can usually provide more stable product supply and professional technical support.
  • In commercial buildings or industrial plant ventilation systems, inorganic fiberglass ducts are widely used due to their fire and moisture resistance characteristics. When purchasing, it is necessary to match the specifications and models of different diameters and connection methods according to the air volume requirements.
  • If the project has high requirements for the airtightness or weather resistance of the air ducts, the supplier can be requested to provide relevant test reports and evaluate the adaptability of product performance based on actual application scenarios.
