Ceiling mounted hepa fan filter unit with black insulation cotton
1. FFU description
The FFU can be modularly connected and used, making the FFU widely
used in clean rooms, dust-free consoles, dust-free production
lines, assembled clean rooms, and local 100-class applications. FFU
has an early and high-efficiency two-stage filter. The fan draws in
air from the top of the FFU and is filtered by a primary and
high-efficiency filter. The filtered clean air is delivered at a
constant speed of 0.45 M/S±20% across the entire outlet surface. It
provides high-quality clean air for clean rooms and
micro-environments of different sizes, different cleanliness
levels. In the newly-built clean room and clean plant type
renovation and refurbishment, the cleanliness level can be
improved, noise and vibration can be reduced, and the cost can be
greatly reduced. The installation and maintenance are convenient,
and it is an ideal component for a clean environment.
2. FFU advantages
1). Beautiful appearance, high air volume, low noise
The computer designed and calculated the cabinet, three-stage
variable speed turbo fan, high efficiency and low noise.
2). High efficiency, high performance
Adopting German NiKi fan, the FFU has first-class quality and
stable performance. FFU has low energy consumption and long life of
100,000 hours; saving production cost and user cost.
3). Convenient and flexible
The FFU is lightweight and ergonomic. The stainless steel carrying
handles on both sides make installation and handling easier, and
the FFU is suitable for different environments.
4). Precision internal structure
With world-class air duct design, never aging. Eliminate secondary
pollution, smooth surface and low wind resistance. Excellent sound
insulation and greatly reduce FFU noise.
Precise diffusing and deflectors on both sides ensure that the wind
flows evenly with a deviation of <10%.
5). Strong production and design capabilities to meet the needs of
customers
In addition to the regular size, it can be customized according to
different specifications of customers. The box material and filter
can be customized according to customer requirements.
6). Security function protection
Three-stage speed regulation meets customers' different air volume
requirements, socket internal insurance, safe and reliable, motor
overheating, overload, overvoltage protection.
7). A variety of accessories are available
Differential pressure gauge, duct flange interface (rectangular or
circular), remote control, ULPA filter, terminal block, insulation
cotton, etc.
8). Strong use
The larger clean room can be filled with hundreds, even several, or
tens of thousands of FFUs at the same time.
9). First-class after-sales service, intimate design and
development concept
Our R&D and design philosophy is to save energy, reduce
operating costs, and reduce initial costs with a clean
room-specific design such as low noise and high efficiency.
The period can meet your needs for the construction, operation,
maintenance and maintenance of the clean room.
FFU mainly uses the industry:
Optical industry, LCD liquid crystal manufacturing, biomedicine,
precision instrument manufacturing, PCB printing and other
industries, wafer processing industry, food processing industry,
semiconductor processing industry, electronics factory, laboratory,
etc.
