For very low feed rates starting at 1 mm/h
At very low feed rates (< 10 mm/h), a potentiometer enables precise speed adjustment.
The maximum feed rate is 300 mm/h.

| • Feed rates < 10 mm/h can be set precisely with the aid of a potentiometer
• Optional: pressure-resistant up to 3 bar, remote control or computer-controlled • Highest short-term and long-term dosing constancy • Disperses virtually all non-cohesive dusts • Easy exchange of different solid material reservoirs and dispersing covers • Easy determination and adjustment of the mass flow • Pulse mode • Device easy to clean • Quick and easy to operate • Reliable operation • Little maintenance required • Reduces your operating expenses |
| • Applications with very low feed rates (< 10 mm/h)
• Filter industry: - Determination of fractional separation efficiency - Determination of total separation efficiency - Long-term dusting - Filter media and ready-made filters - Dust removal filters - Vacuum cleaners and vacuum cleaner filters - Car interior filters - Engine air filters • Calibration of particle measurement devices • Flow visualization • Inhalation tests • Tracer particles for LDA, PIV, etc. • Coating of surfaces |
