Vacuum Feeder Price Stainless Steel Negative Pressure System

Vacuum Feeder Product Introduction

Vacuum feeder, also known as pneumatic vacuum conveying feeder or sealed powder transfer system, is an advanced dust-free material handling solution.

It consists of a vacuum pump (oil-free and water-free), stainless steel suction pipe, flexible hose, PE or SS316 filter system, pneumatic discharge valve, compressed air cleaning device, vacuum hopper and automatic level control system.

The system is fully compliant with GMP standards, making it ideal for pharmaceutical capsule powders, food-grade materials and industrial granules requiring hygienic and contamination-free transport.

Working principle

Step 1: Vacuum pump generates negative pressure inside sealed system
Step 2: Material is sucked into stainless steel suction tube
Step 3: Powder or granules enter flexible hose under airflow
Step 4: Mixture moves into vacuum hopper
Step 5: Filter separates air and material efficiently
Step 6: Clean air is discharged through filter system
Step 7: Pneumatic valve controls material discharge
Step 8: Compressed air pulse cleans filter automatically
Step 9: Level sensor monitors material status
Step 10: System repeats automatic feeding cycle continuously
