Manual bag emptying remains one of the most widespread operations in bulk solids processing, yet it continues to present significant challenges for plant operators.
Across industries such as animal feed, plastics, chemicals, drymix, ceramics and environmental technologies, the daily opening and discharge of bags directly impacts dust containment, workplace safety, energy consumption and production continuity.
As manufacturers face increasing pressure to improve sustainability, reduce plant complexity and protect operators, the demand for smarter bag emptying solutions is growing rapidly.
With the launch of the new RSM polyTUBE™, WAMGROUP introduces a next-generation manual bag emptying unit designed to combine advanced de-dusting performance, full electric operation and compact plant integration in one immediately available solution.
Advanced dust control with integrated polyTUBE™ filtration technology
A defining innovation of the new RSM polyTUBE™ is its fully integrated polyTUBE™ de-dusting system, equipped with advanced nanofibre filter media.
Unlike conventional manual bag emptying units that rely on external filters or compressed air systems, the filtration technology is built directly into the hood, capturing dust exactly where it is generated.
With emissions below 1 mg/Nm³, the unit delivers highly efficient dust containment, helping operators maintain a cleaner workplace and comply with increasingly stringent environmental and occupational safety standards.
A 4.6 m² filtration surface ensures consistent performance even during continuous unloading cycles, while the integrated energy-efficient 24 VDC fan maintains stable negative pressure to prevent dust escape throughout operation.
A key advantage is the fully mechanical filter cleaning system, which eliminates the need for compressed air entirely. This reduces energy consumption, simplifies installation and lowers total operating costs.


A fully electric approach to simpler plant engineering
One of the most relevant market trends in industrial equipment design is the move towards simplified, energy-optimised systems.
The RSM polyTUBE™ responds directly to this requirement through 100% electric operation, powered by a standard single-phase 220 V AC supply.
By removing compressed air from the equation, operators benefit from:
- simpler installation
- reduced infrastructure requirements
- lower maintenance complexity
- improved overall plant efficiency
- reduced energy demand
This approach supports both sustainability objectives and lower total cost of ownership, making the unit particularly attractive for retrofit and decentralised plant applications.
Improved operator ergonomics and workplace safety
Operator’s wellbeing is increasingly central to plant design decisions, particularly in manual handling processes.
The RSM polyTUBE™ has therefore been engineered to improve both ergonomics and safe day-to-day operation.
The lightweight hatch reduces repetitive strain during opening cycles, while the optimised working layout ensures easier, more controlled bag handling.
By positioning the filtration elements directly above the unloading zone, dust is captured at source, significantly reducing airborne particle exposure for operators.
Manufactured in 304 stainless steel with food-grade plastic components, the unit is suitable for sectors with demanding hygiene and product integrity standards.
Compact footprint for flexible integration
In today’s production environments, available space is often limited.
The RSM polyTUBE™ features a compact footprint and space-saving design, enabling easy installation even in confined process areas.
Its height-adjustable supports allow straightforward adaptation to different plant layouts and downstream conveying systems, increasing engineering flexibility for both OEMs and end users.
An additional commercial advantage is its ready-to-use ex-stock availability, allowing customers to shorten project lead times and respond quickly to production demands.
Fast maintenance and global service continuity
Maintenance accessibility remains critical for uptime and long-term performance.
The new RSM polyTUBE™ has been designed for rapid servicing and minimal downtime, with quick-release components enabling fast dismantling of the filter section.
The integrated polyTUBE™ filter can be removed quickly for cleaning or replacement, ensuring consistently high filtration efficiency with simplified maintenance procedures.
As with all WAMGROUP equipment, customers benefit from the support of a global subsidiary and service network, ensuring reliable spare parts availability and technical assistance worldwide.
A versatile solution across multiple industries
The RSM polyTUBE™ is designed for a wide range of sectors, including:
- animal feed milling
- plastics
- chemicals
- glass
- paints, varnishes and resins
- environmental technologies
- drymix
- ceramics
- foundries
Wherever manual bag unloading is part of the process, the unit provides a safer, cleaner and more energy-efficient alternative.
A new reference point for manual bag emptying
With the RSM polyTUBE™, WAMGROUP has redefined the standards of manual bag opening technology.
By combining advanced nanofibre filtration, full electric operation, compact design and immediate availability, the unit addresses the most pressing operational priorities of modern bulk solids handling plants:
dust control, sustainability, safety and uptime.
Reliable. Energy-efficient. Ready for immediate deployment.
