Oil Rotary Vacuum Pumps
VD Series Oil Rotary Vacuum Pumps
(500 to 800 l/min)
 Recently
the move to improve work environments is creating a large
demand for quieter vacuum pumps. Developed to meet this demand,
the VD Series are oil rotary vacuum pumps with low-noise direct-coupled
motors. Designed for easy maintenance, the VD Series makes
daily maintenance and inspection extremely simple. Series
models can be used in a wide range of applications on sites
ranging from research labs (where silence is indispensable)
to production lines.
Features
- Low noise : 59 dB(A) (VD301), 61 dB(A) (VD401)
- Outstanding maintenance
- Enable continuous operation at full pressure.
Applications
- Evaporation, sputtering, ion plating
- Gas substitution/supply, vacuum insulation
- Vacuum drying, freeze-drying, vacuum deairing
- Analysis devices, leak test equipment
- Vacuum packaging, vacuum adhesion/conveying,
vacuum forming, vacuum casting, other
