Envirotech - Model APM 460DXNL -Advanced PM10 Samplers Used for Precise Monitoring

• Automatic Flow Controller with electronic feedback for constant sampling rate throughout the sampling period.
• Brushless regenerative blower with very little noise.
• Heavy duty Induction motor fitted in blower requires no maintenance.
• The blower is immune to voltage fluctuations thus eliminating the need for a voltage stabilizer.
• Electromagnetic interference (EMI) to TVs is eliminated.

Automatic flow controller and auto shut off

In all previous models of particulate samplers in use in the country, the sampling rate varies with dust loading on the filter and fluctuates with changes in the mains voltage. The APM 460DXNL uses an electronic flow controller to automatically maintain a constant sampling rate through the filter/cyclone assembly. The size fractionating cyclone of the APM 460DXNL thus operates close to its designed separation velocity resulting in a sharper cut-off for particulates larger than 10 microns. When the dust load on the filter becomes excessive and exceeds the capacity of the blower the electronic circuits provided in the flow controller automatically shut down the machine.

Owing to its modular design, APM 460DXNL can be easily paired with a gaseous sampling attachment (for monitoring SO2, NOx, NH3, Ozone, etc) as gaseous sampling requires only a few LPMs of airflow. This is possible through an attachable subsidiary unit APM 411 or the more modern APM 411TE. Kindly refer to the respective brochures of APM 411 and APM 411TE for details
