Product Details

product overview

1、 Overview
The HTFC-V cabinet centrifugal fan case is a type of box shaped centrifugal fan with backward tilting blades. The product consists of a low-noise backward tilting blade centrifugal fan, a motor, bearings, transmission components, and a soundproof box. According to different installation positions, 12 different angles of inlet and outlet positions are provided to meet the needs of users in different installation environments. According to different requirements for fire protection and ventilation, there are two types: Type A and Type B. Type A motors are installed outside the box for fire smoke exhaust and have been tested for high temperature resistance by the National Fire Equipment Supervision and Quality Inspection Center in accordance with GA211-2009 "High Temperature Resistance Test Method for Fire Smoke Exhaust Fans". They can operate continuously for more than 60 minutes under high temperature conditions of 300 ℃; The B-type motor is installed inside the box for ventilation and air exchange.
Fans are divided into 17 specifications according to diameter, ranging from 250 to 1600mm. The series has an air volume of 1000 to 300000m3/h and a total pressure of 280 to 2300Pa. The fan is divided into single speed and dual speed. The dual speed fan is equipped with a dual speed motor to achieve two speed regulation, which can meet the needs of users for performance adjustment at different operating points. The fan can also be equipped with a variable frequency motor and variable frequency controller to achieve variable frequency speed regulation. It is recommended to lock the adjustment frequency between 25Hz~50Hz.
To meet the requirements of explosion-proof environments, the fan can be made into an explosion-proof fan with an explosion-proof rating of EXd11BT4, suitable for places with flammable and explosive gases.
To meet the noise requirements of different places, fans can be equipped with mufflers of different lengths, and the soundproof box of the fan can also be thickened to reduce fan noise.
Fans should be equipped with primary, medium, or high-efficiency filters to improve air cleanliness. When configuring filters, actual pressure loss should be considered and the length of the fan casing should be appropriately increased.
2、 Application
Fans can be widely used for ventilation and smoke exhaust in hotels, restaurants, auditoriums, theaters, basements, industrial and mining enterprises, office buildings, and other places, especially suitable for places that require low noise and high air volume ventilation and smoke exhaust.
3、 Processing technology
The fan impeller and casing are made of high-quality steel plates, all produced by molds and welded into shape. The impeller undergoes static and dynamic balance correction, and its balance accuracy is not greater than level 5.6.
The soundproof box body of the fan adopts a frame and box plate assembly design. The frame is made of advanced metal cold bending unit and stretched in one go (aluminum alloy material can also be used according to user needs). The box plate is a color coated plate with a clean and beautiful surface and strong corrosion resistance. The inner layer is high-quality galvanized soundproof micro perforated plate, and the interlayer is ultra-fine glass wool, which can further reduce low noise. The product can be disassembled and assembled on site.
