ROCKER 600, OIL-LESS VACUUM PUMP, 1/4 HP, 650 mmHg - 112985510131. We have tested the equipment and can confirm it functions properly.
I can provide a video of the pump in action if needed. Please feel free to contact me with any questions, thanks! Rocker series pumps are driven by Piston, no need for lubricant, regular oil changes and maintenance, with no oil pollution.
Driven directly by motor with no additional belt-driven transmission; the quality vibration-proof assembly makes Rock series run at the lowest noise level among all other equivalent pumps. Every motor of Rocker series pumps has a built-in thermal protection device to shut off the pump automatically when overheated and then restart it when the temperature cools down.
Every Rocker series pump is equipped with a moisture trap in the air inlet to filter particles, moisture and prolong the life of the pump.
