What is an ISO-6 Cleanroom Classification?

ISO-6 cleanroom classification is one of the highest levels of the cleanroom classes. The ISO cleanroom standards are set by the International Organization for Standardization (https://www.iso.org/standards.html). They are a private international organization with a membership of 167 national standards bodies. The ISO cleanroom classification system used in United States primarily for pharmaceutical cleanrooms, medical device cleanrooms, biotech cleanrooms, and life-science cleanrooms. The Europ

how does fan filter unit work?

How does fan filter unit work？The working principle is to use the FFU fan filter unit's internal fan (motor + impeller) to suck in air (wind), and the absorbed air (wind) passes through the HEPA (high-efficiency air filter) or ULPA (ultra-high-efficiency filter) filter screen below the FFU, filtering out large particles and dust particles in the air, and finally uniformly delivering the clean air at a wind speed of 0.45m/s ±10% to the clean room.

Explosion-proof Fan Filter Unit

An explosion-proof fan filter unit (FFU) is a specialized ventilation device designed for use in hazardous or explosive environments. It is commonly used in industries such as chemical, pharmaceutical, oil and gas, and manufacturing, where the presence of flammable gases, vapors, or dust particles requires strict safety measures.

Key features of an explosion-proof FFU include：

FFU fan dimensions (mm): 1175*575*320, noise level of 52~56 decibels.
The FFU housing and high-efficiency filter adopt a split design, making installation and replacement of the filter more convenient.
It features energy efficiency, centralized computer control, stable operation, low noise, and digital adjustment.
The FFU utilizes a unique air duct design that ensures uniform air velocity, delivering air uniformly at a speed of 0.45 m/s across the entire outlet surface.
The fan employs imported high-efficiency centrifugal fans or domestically produced aluminum impeller centrifugal fans, characterized by long lifespan, low noise, maintenance-free operation, low vibration, and stepless speed control. The fan is reliable in quality, with a working lifespan of 100,000 hours or more.
It is particularly suitable for assembly into ultra-clean production lines and can be used as a standalone unit
