About

• Air intake:The device pulls ambient air into the system.
• Coarse particle separation:A cyclone or impactor assembly separates larger particles (greater than 10 microns) using centrifugal force. These are collected in a separate bottle or container.
• Fine particle collection:The remaining air, now containing only respirable particles (less than 10 microns), passes through a fine filter paper. The respirable dust is retained on the filter.
• Weight analysis:The filter paper is weighed before and after the sampling period. The difference in weight indicates the concentration of respirable dust in the air.

• Cyclone separator:A key component that separates particles based on size.
• Filter paper:A specialized filter, often glass microfibre, collects the respirable particles.
• Blower/Motor:A high-flow blower or a brushless, noiseless motor draws air through the system.
• Programmable timer:Many samplers have a timer to automatically shut off after a set period, and some can record total operating time.
• Automatic flow control:Some models feature electronic control to maintain a constant sampling rate.

• Industrial monitoring:Used in environments like cement plants, mines, and construction sites.
• Environmental monitoring:Measures air quality in urban and rural areas.
• Occupational health:Monitors worker exposure to harmful dust in various workplaces.
• Scientific research:Provides data for environmental assessments and scientific studies.
