Optimizing Industrial Efficiency
we specialize in cutting-edge flow aid systems that solve real-world problems in bulk material handling.
Whether you’re dealing with clogging, bridging, material buildup, or inconsistent discharge, our systems offer precise, durable, and scalable solutions powered by compressed air technology. We represent the advanced EXEN Flow Aid Systems, known for transforming industrial efficiency across mining, cement, energy, and manufacturing sectors.
core solutions
air knockers
Air Knockers use compressed air to strike the hopper wall, dislodging stuck material through impact, not vibration. They’re effective for removing tough build-up without damaging equipment.
Benefits:
- Strong impact force with adjustable pressure
- Ideal for sticky or compacting materials
- Low air consumption compared to air cannons
- Long-lasting and low maintenance

Best for:
Best For: Silos, storage bins, mixing tanks
Great for solving both wall adhesion and arching problems simultaneously.
Pneumatic Vibrators
These vibrators generate linear or circular motion to gently agitate bulk material and keep it moving. They’re excellent where consistent flow is needed without sudden force.
Benefits:
- Continuous vibration without damaging equipment
- Versatile installation on bins, feeders, and chutes
- Air pressure controls the force easily
- Compact and quiet operation
Models:
- ELV8
EPV12A, EPV18, EPV18L, EPV25, EPV35, EPV35L
Best For:
Feeders, conveyors, packaging hoppers
Also used for compacting powder during filling or batching.
Electromagnetic Knockers
Deliver rapid, repeated tapping using electromagnetic force, ideal for removing powder buildup without damaging surfaces. Perfect for light-duty applications where silence, speed, and efficiency matter.
Benefits:
- Gentle, consistent knocking without vibration
- Compact and maintenance-friendly
- Quiet operation in sensitive environments
- Ideal for smaller bins and hoppers
Models:
- EK5A, EK5SA
- EK10A, EK10SA
- EK20A, EK20SA
- EKM1
Best For:
Lab bins, powder feeders, coating stations.
Perfect for eliminating light material sticking without needing force.

How to Choose the Right Flow Aid System
When choosing between air knockers, vibrators, or electromagnetic knockers, consider:
- Material type (fine powder, sticky granules, heavy aggregates)
- Bin/hopper size and wall angle
- Noise sensitivity
- Air pressure availability
- Frequency and force required
Our experts assist clients in configuring the most cost-effective and efficient combination for their operation.
Flow aid systems play a vital role in process optimization and material flow control. Whether installed in a cement silo, mineral hopper, or food-grade bin, these devices prevent issues such as:
- Bridging – when material arches over the discharge point
- Ratholing – where flow occurs only through a narrow core
- Wall Adhesion – sticky materials cling to the container surface
By resolving these problems, companies benefit from:
- Higher throughput
- Reduced manual intervention
- Lower energy consumption
- Better safety compliance
- Less equipment wear
