High Security Filtration Principle
(Nuclear/Particle - Biological - Chemical) Filtration
build efficiency in the filtration process, we tailor, test and add different
filtration modules to make the product fit client needs. To do this and to
ensure a viable end product, we need components producing high filtration
efficiency and causing low pressure drop for the complete system. In some cases, we
compensate the increased pressure drop by a fan.
Success in Reducing Pressure Drop in Particle Filtration
A filter's resistance to the airstream passing through the device, is called Pressure Drop. It is measured as the difference between the entering and exiting Static Pressures of air before and after the filter.
Pressure drop should be kept reasonably low due to the larger fan horsepower and energy required to maintain design airflows. A doubling of pressure drop (PD) will double the required fan horsepower (BHP) (i.e. BHP = K x CFM x PD). Also, increased pressure drop tends to increase pressure differential between airstreams in a ventilation system, which can be undesirable.
Our success in the task of reducing the pressure drop caused especially by the particle filtration module of our filtration solutions, allows us to provide our clients with tailor-made, High Security Air Filtration Solutions for completely new application areas. These solutions are now available for such buildings, air conditioning systems, vehicles and equipment, where High Security Filtration solutions have until now, not been available.
