The Smoke and Heat Exhaust Fan is an essential safety device designed to control smoke, reduce heat, and provide safe evacuation pathways during fire emergencies. Manufactured with advanced engineering by Shandong Wanneng Group, this fan ensures reliable performance in critical situations. Built to withstand extreme temperatures, it helps firefighters, supports rescue operations, and improves building safety by keeping escape routes clear and breathable.

Detailed Description

A smoke and heat exhaust fan is a high-performance ventilation solution specifically designed for fire safety systems. It operates by drawing in smoke and hot gases using a powerful impeller and expelling them through ventilation ducts to reduce smoke density and lower indoor temperatures. Constructed with a high-temperature resistant casing, durable motor, and precision-engineered blades, the fan can operate continuously under extreme heat conditions, ensuring long-lasting reliability.

These fans typically maintain stable performance for 60 to 120 minutes at temperatures between 300°C and 400°C, delivering air volumes from 5,000 to 50,000 cubic meters per hour. With such powerful discharge capacity, they are widely used in large public and commercial spaces such as shopping malls, airports, underground parking lots, hospitals, and industrial warehouses. The integration with intelligent fire alarm systems allows for automatic start-up, ensuring rapid smoke extraction without manual intervention. Compact, efficient, and durable, these fans are a vital part of any modern fire protection and ventilation system.
