Effective Dust Control on Silo Tops

The dust-laden air generated during the filling of silos and bins causes both environmental pollution and reduced equipment performance. VOLDE Silo Top Jet Pulse Filters effectively vent the air inside the tank while capturing particles with high efficiency; they prevent product loss, keep the working environment clean, and prevent filling speed from slowing down. Thanks to their compact, direct-mount-ready structure, they take up minimal space on top of the silo, offer easy maintenance access, and can be engineered to suit different process conditions.

| Jet Pulse Cleaning and Automation

The continuity of filter performance depends on the effective cleaning of the bags. The jet pulse system removes dust from the filter surface with pulses of compressed air, preventing the filter from clogging.

• A varying number of pulse valves depending on body diameter and application
• High-efficiency bag cleaning with compressed air
• Models suitable for blow (pressure-fill) and vacuum-fill systems
• Fully adjustable operation via an electronic control box

_ Via the control panel:

• Pulse sequence
• Valve dwell time
• Repeat interval (cycle time) can be easily adjusted
