Advantages of DC Fan Filter Unit

High-efficiency filtration: High-efficiency air filters that meet international standards, with a filtration efficiency of over 99.995% for particles as small as 0.3 microns. The filter media is made of glass fiber or PTFE, which ensures a long service life and reduces replacement costs.

Reliable, low-energy-consumption fan: Equipped with a brushless DC motor from Zhongwei Technology, the fan offers an extended lifespan, low noise operation, and high energy efficiency.

Sturdy construction and modular design: The unit features a steel housing that is drop- and impact-resistant, making it less susceptible to damage during transportation. Its modular design allows for easy installation; it can be suspended from the ceiling or placed on a workbench, reducing installation costs.

Intelligent control and batch management: A single controller can connect to and intelligently manage multiple FFU air filtration system simultaneously.

Features of DC Fan Filter Unit

A DC motor drives the fan, enabling precise adjustment of airflow based on actual demand. A built-in HEPA/ULPA filter ensures the cleanliness of the output airflow.

The integrated housing design achieves a sealed airflow path. Air drawn in by the fan is purified by the filter and then delivered to the target area at a uniform speed. This not only directly provides clean air but also maintains positive pressure in the area through continuous air supply, preventing the infiltration of contaminated air from outside.

Application of DC Fan Filter Unit

Semiconductor and microelectronics manufacturing: Chip lithography workshop, wafer cleaning area, packaging clean room.

Medicine and biopharmaceuticals: Sterile preparation production line, vaccine filling room, biosafety laboratory (BSL-2/3).

Electronic component manufacturing: PCB board welding area, precision camera module assembly line, lithium battery pole coating room.

Food and medical equipment clean area: Injection bottle washing line, surgical instrument sterilization packaging room, sterile food filling line.

Scientific research and laboratory field: Nanomaterial preparation laboratory, cell culture room, electron microscope observation room.

Component of DC Fan Filter Unit

Pre-filter: The first line of defense, capturing large particles like dust and construction debris, protecting the more sensitive HEPA/ULPA filters downstream.

Housing: Typically made of steel, galvanized steel, powder-coated steel, or stainless steel depending on the environment, offering structural integrity and protection for internal components.

Motor: The driving force behind airflow, with options for both AC and DC motors. AC motors are smaller, cheaper, and more energy-efficient, while DC motors offer easier control and higher speeds but come at a premium.

Airflow equalization device: An increasingly common feature, allowing adjustment of outlet airflow for optimized distribution within the cleanroom. Types include orifice plates, grilles, and power curves, each employing a unique mechanism to achieve this function.

Protective net: Safeguards the final filter from physical damage, often featuring anti-static properties to prevent dust attraction.

Air pipe connecting parts

Facilitate connection between FFU and air ducts, crucial for efficient airflow distribution, particularly in low-cleanliness facilities where static pressure on the ceiling is absent.

Blower wheel

Determines the air volume and noise profile. Forward-curved wheels provide higher air volume and better dust removal, while backward-curved ones are quieter and more energy-efficient.

Final filter

The heart of the FFU, capturing microscopic contaminants. HEPA filters are commonly used, while ULPA filters offer even higher efficiency for critical environments.

Controller

The brain of the FFU, governing operational parameters. Control modes range from simple switches to sophisticated computer-based systems offering single/group control, alarms, and status displays.

FAQ

Q: What is the purpose of a fan filter unit?

A: Fan Filter units are stand-alone units with integrated HEPA-filter, fan and control system. They supply purified air to cleanrooms and laboratories within the life-science, food-and beverage and microelectronic industries by removing harmful airborne particles from recirculating air.

Q: What is the difference between laminar flow and fan filter unit?

A: The fan in an FFU forces air through the filter and then distributes it across the room or enclosure. However, the flow may not be as controlled or directional as with a laminar flow hood, potentially allowing for more turbulence and mixing of air towards the edge of the unit.

Q: What is FFU used for?

A: A fan filter unit (FFU) is a type of motorized air filtering equipment. It is used to supply purified air to cleanrooms, laboratories, medical facilities or microenvironments by removing harmful airborne particles from recirculating air.

Q: What materials are FFUs made of?

A: Laminar flow unit with FFUs is made of special aluminum profiles and stainless steel frames. Units are either designed to be hanged from ceiling or comes with rolling wheels. Transparent hygenic curtains, variable speed controller, differential pressure gauges, test aerosol nozzles are some of the standard accessories.

Q: How often should FFUs be serviced?

A: In a low - contamination environment, you might be able to get away with servicing the FFU and HEPA BOX every 6 to 12 months. This includes checking the fan performance, inspecting the filter for signs of clogging or damage, and cleaning or replacing any worn - out parts.
