Ultimate pressure is the value measured by Pirani gauge. When measured with a Mcleod vacuum gauge, the value will be an order of magnitude lower for vacuum pumps with an ultimate pressure of 1.3Pa or less.

Oil is deteriorated with operating, and becomes the factor of performance shortage. A decrease and the dirt of oil are confirmed, and please regularly add and replace it.
This pump has an unti-sack valve function that is effective to
prevent the oil back streaming when the pump stops.
The function is not 100% guranteed.
If operation is performed at high pressure, oil mist is generated at the exhaust side.
he influence might go out to the pump life according to the characteristic and the amount of the evacuated gas. Especially, longevity is remarkably shortened, and corrosion resistance might not be able to be demonstrated about ammonia and sulfuric acid.
Fluoride rubber material is used for the internal parts of a pump.
There are some for which the chemical resistance of Fluoride rubber materialis not suitable. Especially, be careful of the following chemical. Ammonia, Acetone, Ethylene oxide, Ethylene diamine, Zinc acetate, Amyl acetate, Aluminum acetate, Isopropyl acetate, Ethyl acetate, Lead acetate, Calcium acetate, Cellosolve Acetate, Nickel acetate, Butyl acetate, Propyl acetate, Methyl acetate, Nitroethane, Nitropropane, Nitromethane, Freon.
There is a risk of explosion. Never block the outlet or operate the pump with equipment mounted at the outlet side that blocks the passage of gas. Otherwise, the internal pump pressure increases causing the pump to explode, the oil level gauge to protrude or the motor to be overloaded.
It is a pump only in the room. Please do not set it up in the place, that rain and water splash, and outdoors.
