Air filter SILOTOP® polyTUBE™

dustcartridgefor silo

Overview
SILOTOP® polyTUBE™ is a compact silo venting filter designed for concrete batching plants. The unit combines a stainless-steel housing with vertically mounted polyTUBE™ filter elements using ZERO™ nano-fibre media and an open-profile tubular cell structure to minimise dust residue and maintain filtration performance over time.

Function
The SILOTOP® polyTUBE™ venting filter is intended for intermittent operation. It allows air to vent while retaining dust. Separated dust collected on the polyTUBE™ elements is returned to the silo by an integrated automatic cleaning system controlled by the FILMEC™ electronic controller. Cleaning cycles can run during operation and at cycle end to preserve filter performance.

Features

• Interchangeable with previous SILOTOP® versions
• Compact design: Ø800 mm housing, stainless-steel body with bottom flange
• Low element height: ≈500 mm for safe maintenance on silo roof
• Weather protection cover with lockable quick-release
• Tool-free removal of filter elements
• Vertical polyTUBE™ elements with ZERO™ nano-fibre media
• High-performance pulse mechanical cleaning with energy distribution plate
• Very low dust emission levels (typical <1 mg/Nm3 with cement)
• Low energy consumption < 80 kWh/year (typical)
• Automated management and monitoring via FILMEC™ (USB recording, MODBUS)
• International patents

Benefits

• Reduced installation and operating costs
• Minimised dust emissions for regulatory compliance
• Lower energy consumption and reduced noise (approx. -9 dB(A) vs pneumatic cleaning)
• Safer plant operation due to low differential pressure and data monitoring
• Consistent filtration performance with minimal dust residue

Accessories

• Weld-on bottom ring
• Emission sampling kit
