1、 Overview

1.1. The HTFC (DT) cabinet centrifugal fan is a high-efficiency and low-noise box type centrifugal fan. The product consists of a low-noise forward leaning multi wing centrifugal fan, motor, bearings, transmission components, and soundproof box. According to different installation positions, 12 different angles of air 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 GA211-1999 "High Temperature Resistance Test Method for Fire Smoke Exhaust Fans". They can operate continuously for more than 60 minutes under high temperature conditions of 300C; The B-type motor is installed inside the box for ventilation and air exchange.

1.2. The fan is divided into 13 series of specifications ranging from 9 to 40 according to the machine number. The air volume range is from 1650 to 85000m/h, and the total pressure range is from 180 to 1000Pa. The HTFC cabinet centrifugal fan, after continuous improvement and development, can now be divided into four types: Type I, II, III, and IV. Among them, Type I and III are single speed types, while Type II and III are single speed types The IV type is dual speed, equipped with a dual speed motor to achieve two speed adjustments, 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 a variable frequency controller to achieve stepless speed regulation. It is recommended to lock the adjustment frequency between 25Hz-50Hz.

1.3. To meet the requirements of explosion-proof environments, the fan can be made into an explosion-proof fan with an explosion-proof rating of EXdIIBT4, suitable for places with flammable and explosive gases.

1.4. 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.

1.5. Fans can 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、 Working conditions

Working temperature: -20~+40 ℃ (can operate continuously);

High temperature resistance: 100 ℃ (can operate continuously for 20 hours);

300 ℃ (can operate continuously for 60 minutes);

Humidity: less than 90%;

Medium conditions: air;

Working power supply: three-phase, 380V/50Hz.

3、 Fan 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 in places that require low noise and high air volume ventilation and smoke exhaust.

4、 Fan configuration

4.1 Standard Configuration

● Impeller; ● Pulley and belt; ● Chassis (chassis, current collector, bracket); Belt cover (only type A); ● Motor;

● Silent enclosure; ● Bearings (with casing); Motor regulating track; ● Spindle; ● Import and export flanges.

4.2 Optional parts and accessories (indicate whether to purchase when ordering)

※ Vibration reduction equipment; ※ Control box; ※ Silencer; ※ Docking flange; ※ Filter; ※ Motor rain cover (Type A only).

5、 Processing technology

5.1. The fan impeller and casing are made of high-quality galvanized sheet metal, all produced in molds using riveting, biting and other methods. The surface is clean and smooth, without any welding deformation.

5.2. The silencing box of the fan adopts a frame. The box plate assembly design and the frame are made of an advanced metal cold bending unit by stretching at one time (aluminum alloy profiles can also be used according to user needs). The box plate is a color coated plate with clean, beautiful surface and strong corrosion resistance. The interlayer is a flame-retardant and developable polystyrene foam plate, which can further reduce noise. The inner layer is a galvanized silencing micro perforated plate. The product can be disassembled and assembled on site.
