  • Why Use Vacuum Ejector Instead of Vacuum Pump?

    ✅ No moving parts
    ✅ Compact size
    ✅ Fast vacuum generation
    ✅ Easy installation
    ✅ Lower initial cost
    ✅ Good for decentralized systems
  • Why my pneumatic vibrator stop working?

    1️⃣ Insufficient or unstable air pressure (MOST COMMON)
    2️⃣ Dirty or wet compressed air (VERY COMMON)
    3️⃣ Lack of lubrication (for rotary air vibrators)
    4️⃣ Internal mechanical failure,like the bearing worn,broken piston,cracked housing etc.
    5️⃣ Blocked exhaust or silencer
    6️⃣ Wrong mounting or load condition
    7️⃣ Control valve/PLC or solenoid failure
  • Why we need use the optic fiber microduct connector at the air blowing system?

    Air-blown fiber relies on high-pressure air to push the fiber through microducts.
    A connector:
    1️⃣ To create a continuous, airtight duct path
    2️⃣ To ensure low friction and smooth fiber movement
    3️⃣ To provide mechanical protection and strength
    4️⃣ To enable modular and expandable network design
    5️⃣ To maintain fiber integrity and performance
    The microduct connector is like a sealed joint in a pipeline.
    Without it, the “air pipeline” would leak, and the fiber could not be blown efficiently.
  • Why your cylinder sensor damage during using?

    Firstly all our sensor must connect the load(eg. PLC or relay) during using. Secondly make sure if your system is overcurrent, our reed switch sensor is 100mA, solid state sensor 200mA. Bus door sensor can use for 1A. Thirdly make sure your direction of magnetic induction,some electric cylinder or electric linear actuator used different magnet,we need make some change at the electric board. 
  • Lots of customers will ask if we can supply BMW,Toyota or any other brand car shock absorber?

    Our shock absorber not use for automotive, they are definitely different application. Our shock absorber used for automation control system not for car or truck.
