pölynhallintajärjestelmät

Pölynhallintajärjestelmä (dust control system) is a set of equipment and practices designed to minimize the generation of airborne dust and limit worker exposure in industrial settings. Such systems are used across manufacturing, mining, construction, and processing facilities to improve air quality, reduce product losses, and enhance workplace safety.

Common components include local exhaust ventilation with hoods and ducts, and primary collection devices such as baghouse filters, cartridge collectors, and cyclone separators. In addition, wet suppression and fogging systems, scrubbers, and portable or fixed vacuum units may be employed. Enclosures, process modifications, and housekeeping procedures help contain dust at the source.

Design and operation require understanding dust properties—particle size, density, moisture, and combustibility—as well as process airflow, capture velocity, and ducting. Regular maintenance is essential: filter replacement, leak checks, duct cleaning, and performance monitoring. Systems are equipped with sensors and alarms to monitor airflow and filter condition and to ensure exposure limits are not exceeded.

Applications span mining, wood and metal processing, cement and brick manufacturing, pharmaceuticals, and food processing. Beyond worker health, dust control supports product quality and environmental compliance. Regulations and standards from national safety agencies and international bodies guide assessment, design, and ongoing management, including hazard analyses for combustible dust and permissible exposure limits.

Despite higher upfront and running costs, well-designed dust control systems offer long-term benefits through improved air quality, reduced maintenance, and safer working conditions.
