HEPA Fan Filter Unit FFU Manufacturer

Cleanrooms with a clean class of 1000 (according to FS209E standard), 6 (as per the ISO14644 standard) or above typically use FFU and are installed on ceilings.

Fan filter unit is widely applied in sectors requiring particularly rigorous air pollution controls, such as semiconductors, electronics, food, flat panel displays and biopharmaceuticals.

l 1960s: Before the advent of HEPA fan filter unit, cleanrooms commonly used ducts and high-efficiency air outlets.

l 1980s: The FFU technology was invented in the USA and began to appear in Asia.

l ~2000: FFUs gained application and recognition in major industrial nations worldwide.

l ~2009: Anne Parker began producing FFUs and has manufactured over 300,000 units in ten years.

The performance of FFUs is heavily reliant on the internal fans. Anne Parker utilizes top-quality domestic and international EC series DC fans as the core components of FFUs, ensuring stability and consistency of performance. The filters can be customized to utilize fiberglass filter paper or PTFE filter paper, which optimizes the filters’ initial resistance to meet customers' demands for ultra-low energy consumption.

As a high-tech enterprise in the field of purification equipment, Anne Parker's FFUs have earned widespread recognition and application among customers. Anne Parker has delivered comprehensive and high-quality cleanroom air purification solutions for numerous electronics and pharmaceutical companies.

FFU Structure and Classification：

FFU basic parameters

Noise levels for domestic brand FFUs generally range from 42 to 56 dBA. DC FFUs are typically quieter by about 1-3 dBA compared to AC FFUs of the same size and specifications.

Vibration

Generally less than 1.0mm/s

Face velocity

The common standard wind speed is 0.45 m/s, and the rest can be customized.

Uniformity

Indicates the consistency of the FFU face velocity, which is determined by the design and manufacturing quality of the fan, filter, and diffuser.

External static pressure

Also known as residual pressure, this parameter is critical for the lifespan of the FFU and is closely related to the fan. Typically, an external static pressure of at least 90 Pa is required at a face velocity of 0.45 m/s.

Power consumption

AC systems typically range from 100-300 watts, while DC systems range from 50-220 watts. DC systems consume 30%-50% less power than AC systems.
