RabHirad Cleanroom solutions: Creating Controlled Environments
Cleanrooms are highly controlled enclosed spaces where air quality is closely monitored and maintained to meet specific cleanliness standards. These standards ensure that the concentration of airborne particles is controlled, and every aspect of the room, from construction to usage, minimizes the introduction, generation, and retention of particles according to the ISO 14644 standard. Achieving this level of cleanliness involves supplying a substantial volume of air that has been meticulously filtered through high-efficiency filters.
Mitigating Airborne Contaminants
In RabHirad we use Several strategies are employed to protect cleanrooms from contamination sources. One common approach is to install high-efficiency filters at the air handling unit intake. Additionally, pressurizing the cleanroom to maintain a positive air pressure differential can prevent the infiltration of contaminants through building cracks and openings.
Air Quality Optimization through Filtration
The optimization of indoor air quality in cleanrooms heavily relies on air filtration. Filter media and filtration systems are selected based on your facilities specific requirements. Depth filter media is often the preferred choice for cleanroom applications.
Ventilation Complexity
Cleanroom ventilation is influenced by multiple interconnected parameters, where changes in one component can impact the entire system. Additionally, occupant interactions with the physical environment can affect particle dispersion, potentially disrupting airflow patterns and decreasing ventilation efficacy.
Purification Technologies in RabHirad
Air pollutants in cleanrooms fall into three categories: suspended particles, volatile organic pollutants, and microorganisms. Various purification technologies are employed, including filtration, water washing purification, electrostatic precipitation, and anion technology. These methods purify the air by passing it through a filter medium that captures dust, hair, pet fur, and debris. The fibers in the filter medium create a winding path for airflow. Different types of air filters, such as high-efficiency particulate air (HEPA) filters, fiberglass air filters, and ultra-low particulate air (ULPA) filters, are utilized based on specific needs. In RabHirad we provide your required solutions such as wet-scrubber, bag in bag out (BIBO), HEPA filters, and other requirement for air and water purification.
The HVAC System
The integrity of the cleanroom environment relies on pressure differentials compared to adjacent areas, which are established through heating, ventilation, and air-conditioning (HVAC) systems. The requirements for the HVAC system include supplying clean air in sufficient volume and cleanliness to match the room's classification, introducing air to prevent stagnant areas, filtering outside and recirculated air with high-efficiency particulate air (HEPA) filters, conditioning the air to meet temperature and humidity requirements, and maintaining the necessary positive pressurization.
Filtration: A Critical Aspect
Any air introduced into the controlled zone must pass through filtration. Air filtration involves the separation of particles from airstreams. Filtration methods are diverse and tailored to the size ranges of the particles encountered. Particles above 0.01 microns are typically considered filterable.
HEPA Filters
HEPA, or High Efficiency Particulate Air, filters operate on the diffusion principle to remove particulate matter. These filters are crucial for contamination control, capturing particles as small as 0.3 microns with a 99.97% minimum efficiency. In case of your requirement or GMP Allegations Rabhirad will provide you with all types of HEPA filters and Filter boxes.
ULPA Filters
ULPA, or Ultra Low Particulate Air, filters provide a minimum of 99.999% efficiency (0.001% maximum penetration) on 0.3-micron particles. They are used in ultracleanroom environments where contamination control must exceed what conventional HEPA filters can achieve.
