Düperthal HNA-18 II ATEX F
The exhaust air monitoring unit with fan and activated carbon filter is used for ventilating safety cabinets or chemical storage cabinets equipped with an exhaust air connection. The extracted air is cleaned by a two-stage filtration process and then returned to the ambient air.
The unit can be used for extracting a wide range of chemicals. The list is included in the appendix of the operating instructions and details the substances for which sufficient filter performance can be guaranteed. If substances not included in the list are to be filtered, the filter's effectiveness must be confirmed by Düperthal before commissioning. Please contact our consulting team if you have any questions regarding its use. We would be happy to send you the list.
The product must be installed outside of potentially explosive atmospheres. It may only be used for extracting air from safety cabinets whose interior is classified as a maximum of Ex Zone 2.
