S2H22 to S2H84 Performance

SIAV & VTB Series Blowers

High vacuum without water or oil sealing

The Hibon SIAV & VTB Series are the only dry positive displacement blowers capable of attaining 28" Hg vacuum/93% vacuum. Siav unit special design eliminates: water cooling heat exchangers sewerage Reduces: precooler requirements Provides: oil-free and water-free operation

Applications

• Mobile waste handling units, industrial, municipal, wet and dry.
• Pneumatic conveying (fy ash, chemicals, pharmaceuticals, etc).
• Central vacuum systems (packaging, envelope manufacturing, etc).
• Deaeration (chemical, plastics, brick and ceramics, etc).

Packages

Complete packages available, standard or custom built to customer specifications.
