PF-M is an air-tight and micro powder feeder with min. 1g/hr. It is designed for automatic feeding of solid particles under vacuum and high-pressure conditions. The vacuum level is ≤5*10-2 torr, and it has a maximum pressure resistance of 0.1 MPa. Built-in dispersion blade to prevent powder aggregation, as well as a heating jack with a digital temperature controller. Features Stirring blades built in top of the flange to avoid powder aggregating CF16 Rotatable-Bored 0.5 inches Through Holes delivery port to connect an airtight -system The feeder is controlled by software on a PC by a USB port Power Single Phase 220VAC,+/- 10%, 50/60 Hz ( 110V version is available upon request ) 24VDC motor driving. 860W Max Sample Feeding Tank 500 ml stainless steel container made of SS316 Max. pressure: 0.1 Mpa Max.
