Purchasing Guide

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

  • For procurement requirements that require the use of smoke exhaust ducts, it is recommended to prioritize confirming key technical parameters such as the fire resistance limit and high temperature resistance of the ducts to ensure compliance with building fire safety regulations.
  • In high-frequency application scenarios such as commercial complexes or underground parking lots, it is necessary to choose products with duct cross-sectional dimensions that match the system air volume, while considering installation space limitations.
  • 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.
  • Special scenarios such as industrial plants require attention to the anti-corrosion performance of air ducts. It is recommended to choose materials such as galvanized steel or stainless steel based on the composition of the exhaust medium.

Knowledge Base

Q

This article analyzes the three core requirements of smoke exhaust duct sealant, including high temperature resistance, sealing durability, and construction convenience, to help engineering personnel scientifically choose suitable sealing materials and ensure the safety and reliability of smoke exhaust systems.

Q

Baidu AiGou has found pictures related to different categories of cleanroom smoke exhaust ducts for you, taking you to appreciate the diversity and uniqueness of cleanroom smoke exhaust ducts. At the same time, we also recommend high-quality cleanroom smoke exhaust duct products for you, so that you can easily and quickly find the most suitable cleanroom smoke exhaust duct when purchasing.

Q

When a building catches fire, the smoke exhaust duct transports and replenishes pressurized air, preventing the intrusion of smoke and giving rescue personnel time to evacuate. The common practice is to wrap the galvanized steel sheet air duct with insulation material to ensure that the smoke exhaust duct can maintain effective operation for a certain period of time in the event of a fire. The fire-resistant wrapping outside the smoke exhaust duct is made of glass wool insulation material
