EP450
Features
| EcopositiV series energy saving oil-sealed rotary vacuum pump EP450 reduces its power consumption max. 30% less than previous model by improved rotation efficiency of its rotor. | |
| - | Energy efficiency |
| Our proprietary low friction structure and variable speed control reduces the power consumption of EP450 significantly. | |
| - | Rugged structure and easy maintenance |
|
On EP450, rugged and easy maintenance design are the same as previous model. You can operate EP450 for a long time with appropriate maintenances. |
|
| - | Low cost of ownership |
|
With rotational speed controller, you can operate EP450 with one size smaller motor than normal. It won't take you long to recoup the initial cost with reduction of the running cost, including electricity bill. |
|
| - | You can retrofit EP450 parts into your P450. |
