Critical Fire Protection for HVAC Systems
Safety is the top priority. Our 70℃ Fire Dampers are key components for fire protection in ventilation systems. They are normally open. When the air temperature reaches 70℃, they close automatically. This stops smoke and fire from spreading through ducts. We offer standard models (close only) and models with micro-switches for signal feedback. Electric models allow remote control. Yancheng Lima Air Conditioning Engineering Co., Ltd. has been providing fire safety products since 1996.

Where They Must Be Installed
Building codes require fire dampers in specific places. Our 70℃ Fire Dampers must be installed where ducts pass through fire barriers. This includes walls and floors separating fire zones. They are also required where ducts go through ventilation or air conditioning equipment rooms. Other locations include passages through rooms with high fire risk, both sides of expansion joints, and at the junction of vertical shafts and horizontal ducts. Installing them correctly helps contain fire and smoke.

Durable Materials for Reliable Operation
When a fire happens, the damper must work. Our 70℃ Fire Dampers are built to last. The body and blades are made from stainless steel, galvanized steel, or aluminized zinc steel. These materials resist high temperatures without deforming. They provide reliable closure when needed. We test our dampers to ensure they meet safety standards. Our factory in Yancheng uses advanced equipment for precision manufacturing. You can trust our fire dampers to protect your building and its occupants.
Frequently Asked Questions (FAQ)
Q: How does the damper close?
A: A thermal fuse melts at 70℃, releasing a spring that closes the damper blades.
Q: Can I get a model with remote control?
A: Yes. We offer electric models that allow remote closing from a fire control panel.
Q: What materials are available?
A: We offer stainless steel, galvanized steel, and aluminized zinc steel to suit different environments and budget needs.
