¡á Á¦Ç°Æ¯Â¡(Features) * It is a type applicable for the voltages all the world, for a multi-voltage motor is equipped to GLD series. 2 types, for single/three phase, are available. * As it is applicable for various voltages by a simple wiring change, there is no necessity to change the motor for use in accordance with a voltage in the countries where the pump is used. * For the single phase, it is used at 100V-120V or 200V-240V. The functional performance such as gas-ballast mechanism, oil back-flow prevention mechanism, large-sized oil-level gauge, etc. is equal to GLD Series. It is CE self-declared products.

Caution
GLD Series, compared with G Series, is markedly upgraded. For the sake of having the maximum performance, in addition to notes for G series, be careful of also the followings.
1.
GLD series is capable of reaching to a high vacuum area (10-2 Pa). Flanges, vessels usable at a high vacuum are required.
2.
An oil-sealed rotary pump is not recommended for continuous operation near atmospheric pressure.
