on energy with high efficiency, and saving over 20% electric energy over
traditional models
2) the actual-bevel gear is made of chromium-manganese-titanium with
carbon-nitride surface treatment. this ensures long usage life spans and
high rigidity
3) a mechanical seal is available to prevent oil leakage.
4) inside protectors are available to avoid the motor being accidentally
