  • Exhaust Fans & Extractor Fans Application
    Exhaust fans are widely used in real life, not only in homes but also in industry. Below we introduce the application of several types of exhaust fans in production and life.

    1. Industrial exhaust fan:
    It is used in port containers and large storage warehouses to maintain low temperature and dry environments, and workshops that need to maintain a certain humidity and low temperature, such as cotton factories, knitting factories, etc .; this exhaust fan is widely used in people flow Many intensive places, such as: KTV, supermarkets, Internet cafes, etc .; workshops that generate odors and perform high temperature operations, such as: shoe factories, food factories, glass factories, plastic factories, etc. Maintain a certain temperature and humidity in the greenhouse.

    2. Bathroom exhaust fan:
    The exhaust fan can exhaust the dirty air in the bathroom outdoors, keep the air fresh in the bathroom, and create a comfortable and comfortable environment. The exhaust fan installed in the bathroom can be a ceiling extractor fan or a wall. Exhaust fan. Ceiling type exhaust fan the ceiling type extractor fan has a good appearance and can be installed on the ceiling of a bathroom. The duct of this ventilating fan is short, so it is necessary to purchase a ventilation duct matching the duct during installation. Wall-mounted bathroom exhaust fan Wall-mounted exhaust fan has a small volume and can be embedded above the wall, but its narrow cross section of the exhaust port results in weak ventilation, so it is only suitable for installation in a bathroom with a small area. The window type exhaust fan is different from the previous two types. It has single and double two-way operation modes, which can exhaust indoor air and supplement outdoor fresh air. Therefore, the window type exhaust fan has a wider application, the effect is better.

    3. Kitchen exhaust fan: Many people will say why the exhaust fan has been installed in the kitchen. This is because the cooker hood only plays the role of fume hood, and cannot play the role of ventilation. The installation of exhaust fans can effectively control the ventilation, ventilation, stuffiness, high temperature, and odor removal of the kitchen.

    The following are some common kitchen extractor fan installation methods. You can consult the supplier or seller in detail when purchasing.

    Wall-mounted exhaust fan: The exhaust fan is installed on the wall. First, accurately measure the outline size of the exhaust fan and the exact position of the screw whole installation, mark the corresponding position, and then use a steel chisel or a portable impact drill to wall Cut out mounting holes in the body. A wooden block (or wooden pillow) is buried in the hole, and an exhaust fan can be installed after being embedded with mortar, and it is fixed one by one according to the installation instructions.
    Window-type extractor fan: The window-type exhaust fan is installed on the window, which is mainly from the stove to the window, which is convenient for draining the cooking liquid.
  • Different Types of Exhaust Fans & Extractor Fans
    1. According to the ventilation mode
    Household exhaust fans can be divided into three types: exhaust type, suction type and combined type according to different ventilation methods. As the name implies, the exhaust type is only responsible for exhausting indoor dirty air, and other air inlets are responsible for entering fresh air; the suction type and exhaust type are the opposite, they are only responsible for inhaling fresh air and exhausting dirty air from other channels; the combined type is a combination of This is responsible for indoor air intake and extractor.

    2. According to the inlet and exhaust ports
    Household exhaust fans can also be divided into partition type, duct exhaust type, duct inlet type and full duct type according to the inlet and exhaust ports. Partition wall type refers to the installation on the wall. Both sides of the installation wall are free space, which can be directly ventilated through one side of the partition wall to the other side; while the duct exhaust type is where one side enters from the free space. Air, the other side is exhausted through the duct; the ducted air intake type is exactly the opposite of the ducted exhaust type; in addition, there is a full ducted type, which refers to the installation of ducts on both sides of the exhaust fan, and the intake and extractor through the duct.

    3, According to the installation location
    Inline exhaust fan can be divided into wall-mounted, window-mounted and ceiling-mounted according to their installation positions.
    Wall-mounted exhaust fan: The exhaust fan is directly installed on the hole in the wall. The wall-mounted exhaust fan is generally small in size. Due to its narrow cross-section, the ventilation force is weak, and it is generally suitable for relatively small and closed spaces.
    Window exhaust fans are also known as exhaust fan with shutter: Install the exhaust fan on the window, which not only does not need to make holes in the wall, but also saves the exhaust duct. However, the window exhaust fan occupies the area of the window and also blocks the light. Please pay attention to this when purchasing residential exhaust fans.

    Ceiling exhaust fan: The exhaust fan is mounted on the ceiling of the roof, which is more beautiful. However, this type of installation usually requires ventilation ducts of suitable length.

    Commercial and industrial exhaust fans mainly use the principle of air convection for ventilation. They are mainly installed on windows. Fresh air is naturally sucked in by the opposite door or window of the installation site, so that the indoor hot air and foul air are quickly discharged outside. Air enters the room. The types of commercial and industrial exhaust fans can be classified according to the extractor outlet, which can be roughly divided into: cross-flow exhaust fans, axial-flow exhaust fans, centrifugal exhaust fans, full duct extractor fans, duct inlet exhaust fans, duct exhaust fans , And partition-type exhaust fans. These exhaust fans are classified according to the inlet of the fan and the form of air flow.

    Based on the above, the types of embedded exhaust fans are summarized for everyone. There are many types of exhaust fans on the market, and different types of exhaust fans are suitable for different places. You need to choose according to the place of use.
  • Exhaust Fan & Extractor Fan Production In China


    In 2017, the global exhaust fan industry, China accounted for 50.86% of the production market share
    Globally, the exhaust fan industry market is low in concentration, because the manufacturing technology of exhaust fans is relatively mature than some high-tech equipment.

  • Exhaust Fan System
    Ventilation fan, also known as exhaust fan, is an air-conditioning appliance that is installed on walls or doors and windows in home decoration to exhaust indoor air or suck outdoor air to keep indoor air fresh. During the operation of the extractor fan, a negative pressure environment is formed in the room, and then the exhaust effect is achieved.

    In a sense, the exhaust fan and the extractor fan are actually the same type, and both of them are driven by electric motors to rotate the blades to drive the airflow. Such a process is a process of air exchange in the sense. Exhaust fans and exhaust fans are machines that perform this type of air exchange.
    In fact, industrial exhaust fans, industrial exhaust fans in a sense is an enhanced version of exhaust fans, exhaust fans. The effect is better, so it is more suitable for large-scale factories and enterprises to use, and it can discharge indoor foul gas to the greatest extent, and achieve a large-area ventilation effect.
    Due to the high air-tightness of modern buildings, general indoor air is difficult to circulate. If the window opening time is small, it is difficult to guarantee the indoor air quality. In order to improve indoor air quality, we must use ventilation equipment to Displace fresh air. There are many types of ventilation equipment, the following two common types of ventilation equipment:

    Exhaust fan system

    1. The exhaust fan system has low noise. The international noise standard is 40 dB, and the European and American standard is 30 dbs. The standard space exhaust fan system has only 26 decibels, and the master bedroom, elderly room and baby room can enjoy quiet sleep at night.

    2. The standard space exhaust fan system has both exhaust and intake air, and fresh space can enter every corner of the room.

    3. The standard space exhaust system can continuously operate for more than 80,000 hours, and requires less than 1 kWh per day.

    The following is a chart of common types and sizes of some common exhaust fans:

  • Dayton Exhaust Fans Introduction
    The working principle of the Dayton exhaust fan is that during the process of exhausting air outward, the indoor air pressure will drop, the indoor air will become thinner, and forming a negative pressure area, and the air will flow into the room due to the pressure difference. In practical applications of industrial plants, the Dayton exhaust fansare usually installed on one side of the plant, the air inlet is on the other side of the plant, and air flows from the air inlet to the exhaust fan to form a convection blower. During this process, the doors and windows near the exhaust fan remain closed, forcing the air into the workshop by compensating the air from the door and window on the side of the air inlet. The air flows into the workshop in an orderly manner through the air inlet, flows through the workshop, and is exhausted by the exhaust fan. The ventilation is thorough and efficient, and the ventilation rate can reach 99%. Through specific engineering design and designing the ventilation speed and wind speed as required, any high heat, harmful gas, dust and smoke can be quickly discharged from the workshop, and any poor ventilation can be completely solved at one time. Ventilation can be achieved within seconds of turning on the fan.

    Industrial Dayton exhaust fans used in general environments are mainly composed of fan blades, motors, control switches and frames.
    There are two types of AC power supply for industrial exhaust fans: single-phase and three-phase. Household industrial exhaust fans or suction and exhaust dual-use industrial exhaust fans use a single enclosed motor to adapt to harsh environments (steam oil mist and dirty dust places). Televisions generally use ball shafts, and small-size industrial exhaust fans that require low noise use powder metallurgy oil-containing bearings. And the industrial exhaust fan motor with anti-vibration, parking noise and oil storage devices, the motor runs low noise, long-term work without refueling. The frame of industrial exhaust fans is usually made of shaped steel plates. The frame is equipped with louvers that can be opened and closed. There are many types of industrial exhaust fans, with the number of blades ranging from 3-8, and the fans should have high mechanical strength. Most industrial exhaust fans use five or six fan blades. Most of the fan blades are injection-molded at one time, with good balance and low noise.

    Professional design Dayton has been focusing on the R & D, manufacturing and sales of ventilation equipment for many years, and has been identified as a "high-tech enterprise". Dayton has an advanced design platform and a rich R & D database, and uses CFD technology and advanced CAD software to continuously optimize and improve product performance and ensure safe and efficient use. The newly developed series of industrial centrifugal fans, such as KTF and DF55, have reached national energy efficiency standards.
