Fire smoke exhaust fans are the core equipment of building fire protection systems, responsible for expelling toxic smoke and buying time for personnel evacuation during fire incidents. According to the "Code for Fire Protection Design of Buildings" GB50016 and "Technical Standard for Smoke Management and Exhaust Systems in Buildings" GB51251-2015, exhaust facilities must be installed in underground rooms exceeding 100㎡ and evacuation corridors exceeding 20m in length.
Expel toxic high-temperature smoke during fires (above 280°C)
Maintain positive pressure in evacuation passages to prevent smoke intrusion
Create favorable conditions for fire rescue
Reduce temperature damage to building structural components
Xinfeng fire smoke fans are all certified by the Ministry of Public Security Fire Products Quality Certification Center (CCCF), complying with GB51251-2015 and GB12361-2013 standards.

Q: Does the fire fan require regular testing?
A: Yes. Monthly manual start test, quarterly automatic start test, annual comprehensive inspection. Xinfeng provides annual maintenance services.
Q: What is the difference between fire smoke exhaust fan and supply fan?
A: Fire smoke exhaust fan expels smoke, supply fan sends positive pressure to evacuation passages. They work together to form a complete smoke management system.
Q: How long is the fire fan certification valid?
A: CCCF certification valid for 5 years, requires renewal. Xinfeng certificates remain valid and can be verified at any time.
Q: What is the delivery time for Xinfeng fire fans?
A: Standard models 10-15 days, custom models 20-30 days. Fire equipment urgent orders prioritized.
