Features EFFICIENT WORK: This vibrator is pneumatically powered and has good vibration amplitude (vibration force 1220 to 3160 N) and frequency (rated frequency 26000 to 33000 times/min). STAINLESS STEEL MATERIAL: This vibrator is made of premium stainless steel, which has a strong durability and a long lifespan, corrosion resistant and high temperature resistant to withstand harsh environment. SAFE AND QUIET: Very quiet, with a decibel (db) range of 60 to 75. Torsion generated by eccentric machining at high speeds produces a powerful dynamic excitation force that ensures safety. EASY INSTALLATION: The vibrator is appropriate for integration of a variety of devices due to its compact structure, small volume, and ease of installation. EASY OPERATION: Start and stop immediately. According to pressure, the vibration force, vibration frequency, and vibration power may be changed, resulting in great functions that satisfy your needs.
