Pre Filtration System
Pre-Filtration System of the Air Purification System Class
Exposure to contaminants of both, biological and non-biological origins can be reduced by following several measures. There are many new and effective measures are evolving, indoor air filter is one of them. It is considered as an imperative component of environmental control measures. Home's HVAC system, portable room air cleaners, or a combination of the two can be used for indoor air filtration.
An important attribute of an air filter is a balance of air flow for adequate ventilation; small particles filtration efficiency; and capacity to allow for cost-effective maintenance schedules without even affecting airflow and efficiency.
Pre-filtration frames with filters are added to the outside of the device for protecting the high efficiency particulate air filter inside the unit during building activities. It extends the lifetime of the high efficiency particulate air filter inside the unit. The prefilters are provided in packages and can be conveniently changed.
This system generates a positive or negative relative air pressure in the room, depending on the way it is installed. It can easily obtain up to 10 Pascal pressure differences.
