Dust extraction constant airflow controller

In all dust extraction systems, airflow varies according to filter pressure. Ideally however the airflow should be kept constant throughout the life of the filter. As an alternative to a motor inverter control, R&B Industrial have developed a constant airflow controller. This is using modulated dampers as a cost effective and innovative way of controlling the airflow.

Our constant airflow controller is able to maintain a constant airflow by sensing and compensating for filter differential pressure throughout the life of the filter. This optimises extraction system performance and extends the life of filters.

The constant airflow controller can be retrofitted to existing extractor units. Once installation is complete the minimal attention is required. Additional features can be included, for instance; remote audible alarm, differential pressure alarm, bin level alarm, high emissions alarm and continuous recording systems

ATEX

In certain atmospheres when a mixture of air gases, vapours, mists or dusts combine in a way that could cause ignition then ATEX certified equipment is needed to comply EU legislation to mitigate the potential of explosions.

In such environments ATEX certified equipment will need to be used to mitigate the potential of explosions, the problem with this is the cost of the ATEX equipment can be over three times as much as the same non-ATEX device.

At R&B Industrial we create control systems that remove the dangerous atmospheres, thus removing the need for ATEX certified equipment resulting in a more cost effective option for our customers.
