HEPA BOX / Filters
Used in supply ventilation for cleaning air from pollutants of all types of production facilities in the electronics, pharmaceutical, chemical, food industries, and in precision engineering machinery, laboratories. It is also used in exhaust ventilation systems to protect against hazardous emissions. The design is installed in the ceiling grid system as well as in wall systems.
The structure consists of prefabricated elements powder coated in RAL 9016 antistatic (standard color, can be replaced at the customer's discretion). The standard size of the structure according to the ceiling system cells is 1.2 x 1.2 meters. It is allowed to change the size, due to the impossibility of installing the standard size and in case of passing the installation according to the design parameters.
The main elements of the installation are:
> plenum above cleanroom ceiling
> Hepa-filter frame
> HEPA-filter
> diffuser / perforated grille
