Characteristics of HTF stainless steel fire exhaust fan:

The HTF high-temperature fire exhaust fan has high efficiency, energy saving, smooth operation, low noise, high temperature resistance, reasonable structure, easy installation, and can be installed vertically, horizontally, or suspended.

1. The fan is designed with a special motor cooling system and a built-in motor type

2. Advanced aerodynamic design blades (forward sweep, forward tilt) are used to reduce noise by 8-10dB (A) and power by 6% compared to existing fire fans

When the temperature of the main air duct medium is 280 ℃, it can operate continuously for more than 30 minutes, and at 150 ℃, it can operate continuously for a long time.

The production of wind turbines is controlled by a standard quality system and follows the following "specifications" jointly issued by the State Administration of Technical Supervision and the Ministry of Construction of the People's Republic of China.

1. Code for Fire Protection Design of High rise Civil Buildings (GB5004-95)

2. Design Fire Prevention Code for Garage and Parking Lot (GB50067-97)

3. The provisions of the "Code for Design of Civil Air Defense Underground" GB50038-94

This product has four series in centimeters: ① Normal pressure single speed ② Normal pressure dual speed ③ Medium pressure single speed ④ Medium pressure dual speed

It can be used for fire and smoke exhaust in various buildings, as well as for smoke exhaust and ventilation in various buildings, civil air defense projects, underground railways, mines, tunnels, etc.

1. high temperature resistance

The fan is designed with a special motor cooling system, which can operate continuously for more than 30 minutes when the temperature of the main air duct medium is 280 ℃,≤It can operate continuously for a long time at 150 ℃.

2. Small size and light weight

The basic form of this fan is axial or diagonal flow fan, which can be directly connected to the air duct or installed on the wall. The installation form can be vertical or horizontal, occupying two-thirds less space and reducing weight by more than half compared to centrifugal fans with the same air volume, greatly saving floor space.

• Simple construction and high efficiency

The fan consists of five main parts: ① impeller ② motor ③ internal circulation air cooling system ④ guide vanes and inner cylinder ⑤ easy disassembly and maintenance of the outer cylinder.

A new product developed using advanced CAD software for multi-objective optimization design has been tested and shown to have a fan efficiency greater than 80%, with some large machine numbers exceeding 85%. It also features a flat efficiency curve, which is beneficial for energy conservation.

• Easy to install

This fan can be installed horizontally or vertically according to the requirements of building construction, with a power supply of three boxes of 380V, 50Hz

• Calibration code description

• Selection of fan performance

A.The performance of the fan within the highest efficiency range listed in the performance table is divided into five performance points according to the air volume, and the selection should be based on the performance table. Under the rated air volume of qualified products with factory style, the total pressure value error shall not exceed± 5%, the performance shall be based on the standard state of the table, and the performance specified in the technical documents or order requirements shall be subject to the standard state.

B.If there are special requirements for performance such as air volume, total pressure, installation dimensions, etc., our factory will design and produce them separately for you.

C.The performance of the fan is shown in the performance table:
