New extraction solution for flammable gases and vapours
With the ACD 400.1 Ex extraction and filter system, ULT presents a new solution for removing atmospheres with flammable components.
The system, equipped with an explosion-proof fan in accordance with ATEX Ex II 2G T3, was developed for the extraction and filtration of dry, flammable and non-flammable gases and vapours in concentrations of up to 20% of the lower explosion limit.
It is a modular, two-stage storage filter unit consisting of an M5 dust pre-filter and two adsorption filter modules (activated carbon). To prevent the ignition of flammable gases and vapours in the filter, the activated carbon filter elements and downstream components - such as the ATEX-compliant fan and the ATEX-compliant motor - are earthed and designed without ignition sources.
In addition to its properties as an Ex device, the ‘ACD 400.1 Ex’ offers further user benefits such as extremely quiet operation, low energy consumption and high flexibility with regard to changing workstations or emission types. The filter cassettes are electrically conductive with a potential equalisation connection and also offer a high safety standard for users when changing filters. A T3 blower is installed in the device, which is why gases of temperature classes T1-T3 can be extracted safely.
The extraction system can be equipped with various collection elements (extraction arms, hoses, pipes) of different sizes and types.
Due to the high degree of gas separation, the filtered clean gas can be fed back into the work area via the recirculation mode integrated as standard. For applications with carcinogenic, mutagenic or reprotoxic gases, the devices can be equipped with an exhaust air connection for exhaust air operation.
An extensive range of accessories is available for the ‘ACD 400.1 Ex’ unit, which has been specially developed for applications with flammable gases.
