A series of food-grade pneumatic vibrators from Martin Vibration Systems (MVSS; Marine City, MI) enhance movement of moist, powdered, granular or pelleted material through small hoppers, bins and tubes. The Bantam Series offers powerful vibration and versatility in a small package, and the low-noise, linear units are washdown-safe and are purpose built for sanitary applications. They are engineered to endure continuous use, even at high and low ambient temperatures (32°-140°F). Operating lubrication free with a low air consumption results in consistent bulk material flow with less downtime, at a lower cost of operation. The series include the following three options:
- The NTS 80, a non-impacting linear vibrator designed for applications with delicate construction and space constraints. Suitable for overcoming static friction and removing dry material build-ups, these vibrators are particularly effective on vessels with narrow discharge apertures and small volumetric capacity. With a compressed air input of 30 PSI (2 BAR), the unit puts out a centrifugal force of 3.3 lbs, with a nominal frequency of 6,360 VPM, while consuming only 0.7 ft3/min (20 l/min ).
- The NTP 18, which is roughly the size of a pill bottle, but engineered to produce enough power to eliminate ratholes and bridges. With an input of 30 PSI (2 BAR), the design puts out 33.1 lbs of centrifugal force, with a nominal frequency of 6600 VPM, using just 0.4 ft3/min (12 l/min).
- The NTK 8AL HA, which features the instant on/instant off design, providing the exact vibration required while keeping energy use and noise to a minimum. The long rod-shaped NTK 8AL HA is 7/8″ in diameter and 6″ tall. At an input of 30 PSI (2 BAR), the centrifugal force created is 3.5 lbs, with a nominal frequency of 1,858 VPM, while consuming 0.2 ft3/min (6 l/min).
