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.
- Noise (with oil mist trap) :
54dB (A) (VD151), 58dB(A) (VD301/VD401),
64dB (A) (VD601), 65dB (A)(VD901)
Outstanding maintenance
Enable continuous operation at full pressure with option (VD301/VD401/VD601)
- 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, etc.
