Dust filter housing CANISTER

laboratoryfor healthcare facilities

CANISTER safety system are duct containment systems for the safe replacement of high efficiency, HEPA, ULPA or activated carbon filters and they are designed to filter exhaust air from environments containing toxic or harmful contaminants. These systems are mainly used in industrial, laboratory and process applications and are installed directly in the hazardous environment. In the Bag-In/Bag-Out procedure spent filters are sealed inside the barrier bag and then sent for disposal, never coming into contact with any operator. Duct containment systems for the safe replacement of high efficiency, HEPA, ULPA or activated carbon filters. The system guarantees the highest tightness class thanks to the double-lip flanges, the sealing gaskets and the continuous welding. The mechanical resistance of the housing to air pressure is ±5kPa according to ANSI/ASME 510:2007. The tightness class of the system is Class 2 according to ISO 10648-2, under standard operating conditions.
