Explosion proof FFU purification unit, also known as explosion-proof FFU fan filtration unitExplosion proof FFU fan filter unit, explosion-proof FFU customized manufacturer introduction. Explosion proof FFU is different from ordinary FFU.The wide application of explosion-proof FFU fan filtration unit:
1. Use different fan filter units in different situations, and adopt corrosion-resistant fan filter units, high-temperature resistant fan filter units, explosion-proof fan filter units, etc. according to the situation of the clean room. The materials used in the production of different FFU fan filter units are also different. Here, we will briefly explain the production and application of explosion-proof FFU fan filter units.2. Before making the explosion-proof FFU fan filter unit, it is necessary to first purchase some universal accessories. The air filter should use a HEPA high-efficiency filter screen, which can save energy by at least 48% under initial resistance conditions. The explosion-proof FFU fan filter unit has a self powered air supply device, while the fan of the fan filter unit produced by our company uses a DC fan from the United States, which has the characteristics of energy saving, stable operation, low noise, computer centralized control, digital speed regulation, etc.3. With the deteriorating air quality and increasingly strict standards, FFU fan filtration units have been widely used in various industries. Explosion proof fan filter units are generally used in the semiconductor industry, electronics industry, flat panel display industry, disk drive manufacturers, as well as optical and biological industries that have strict requirements for indoor air cleanliness. They quickly occupy the clean industry market due to various factors such as ease of use and reasonable price.4. The explosion-proof FFU fan filter unit adopts a special flow channel system design, which has the characteristics of low noise, uniform wind speed, low energy consumption, less vibration, high static pressure, etc. The control system of the fan can adopt a multi-stage or stepless speed regulation system, which is more conducive to energy saving and greatly reduces the operating costs of the enterprise. The explosion-proof FFU fan filter unit is installed in a clean room, which can improve the cleanliness level of indoor air and greatly reduce the operating costs of enterprises. It is an ideal purification and filtration device for clean rooms. The explosion-proof FFU fan filter unit is a clean and explosion-proof FFU fan filter unit that combines the top of the air purification industry. One side of the surface of the FFU fan filter unit is fixed with an explosion-proof electrical junction box, and an explosion-proof fan composed of an explosion-proof motor is installed inside.

Explosion proof FFU installation instructions:
Installation steps for explosion-proof FFU: 1. Carefully remove the fan unit and high-efficiency filter from the transport packaging box, and check if any components have been damaged during transportation.

Specific details may also refer to the FFU installation introduction earlier
Step 2 of explosion-proof FFU installation: Remove the plastic bag and protective film, and place the fan unit and high-efficiency filter in a clean room.

Step 3 of explosion-proof FFU installation: First, firmly place the high-efficiency filter (with rubber sealing strips attached to both the inlet and outlet sides) on the ceiling frame. Then place the fan unit on top of the high-efficiency filter and press the high-efficiency filter tightly by gravity.

Step 4 of explosion-proof FFU installation: According to the wiring diagram in Part IV and local electrical regulations, use cables to connect the fan unit to a power source of appropriate voltage (380V three-phase AC).
Requirements for safe use of explosion-proof FFU:
To avoid fire, electric shock, or personal injury caused by the use of explosion-proof FFU, please strictly follow the following instructions:
A. Explosion proof FFU installation, circuit connection, and wiring must be completed by qualified technicians and must comply with all applicable specifications and standards
Standards and regulations, including fire safety regulations.
B. When cutting or drilling holes in walls or ceilings for explosion-proof FFUs, please be careful not to damage the protective layer or other hidden functional parts of the wires
Item.
C. If the explosion-proof FFU is installed in an environment that may be damp, appropriate signs should be affixed to indicate the correct usage method.
D. This unit can only be used in the manner designed or recommended by the manufacturer. If you have any further questions. Please contact the manufacturer.
E. Before repairing or cleaning the explosion-proof FFU, please turn off the power switch on the maintenance panel and cut off the power to prevent others from accidentally turning on the power switch.

How to disassemble and replace the HEPA/ULPA filter of the explosion-proof FFU?
Before disassembling and replacing the HEPA/ULPA filter of the explosion-proof FFU, the power cable socket of the fan unit must be disconnected.

Tool requirements: None

Step 1. Remove the fan unit from the ceiling.

Step 2. Remove the old HEPA/ULPA filter from the ceiling rack.

Step 3. Place the new HEPA/ULPA filter on the ceiling rack and reinstall the FFU according to the installation sequence.

Note: Before replacing the HEPA/ULPA filter, carefully inspect the new filter for any damage or defects.
