Motorized Fireproof Damper (MFD) with EI standard

Currently, with convenience in the works, many types of wind valves have appeared with many different functions. However, the EI Motorized fireproof Damper (MFD) is highly appreciated for its outstanding advantages compared to other types of air valves. So today, let’s go with P69 Mechanical Factory through the article below to know more about this type of air valve and why it is superior to other types of air valves!

What is Motorized Fireproof Damper (MFD) with EI standard

– Motorized Fireproof Damper (MFD) with EI standard is used in fire compartment networks. The valve also has the same structure as normal air valves, but the EI fireproof MFD engine air valve has a superior advantage because it is a self-closing fire prevention valve with Actuator ON/OFF type activated. by thermal relay, fire resistance limit EI 30 (30 minutes) to 120 (120 minutes)

– E (Integrity) is the limit at which the structure of the material is perfectly maintained without breaking, falling, etc., regardless of the heat transfer capacity of the material. This limit is usually determined for application in fireproof solutions such as manufacturing partitions, walls, ventilation systems, etc.

– I (Thermal Insulation) is the limit at which the material retains stable thermal insulation ability. The main structure of the material is not damaged by heat. Determine this limit to apply to fireproof solutions, ensuring when a fire occurs, the materials are kept intact, the fire cannot spread, the temperature on the surfaces of the materials is guaranteed.

Working principle of Motorized Fireproof Damper (MFD) with EI standard

– Engine air valve MFD Fireproof EI works on the principle of temperature on the pipeline and the outside temperature is still windy.

In addition, when the temperature in the pipeline of the wind valve rises to 70-80 degrees, the valve fuse will melt and break, the air vents will close, helping the fire not to spread from the air. from place to place. Therefore, EI fireproof MFD engine air valves are known as good quality air valves because they prevent the spread of fire to protect people’s safety.
