The BPHD is a heavy duty blast panel with an IP rated 100% gas, dust and weather seal. For use with inert gas systems, electrical switchgear and transformer building protection and explosive atmosphere building protection. Ideal for extreme environments and applications. Also used for large FVA ventilation requirements in buildings with gas suppression systems, such as transformer bays, where extremely low leakage is required when closed for gas agent concentration duration whilst maintaining a very high level of blast protection. Motorised version BPHD MOT available for when ventilation is also required.
