Roots Blower


 A special feature of the blowers is to provide with discharge port composed of slits which results in smaller pressure pulsation, very low noise and small vibration, thus IRS(T) (Low noise type) blowers and vacuum pumps have achieved good reputations of the users of versatile fields.

Special note J-type blowers are ITO’s side-cover, jacket cooling type blowers. With J-type blowers, cooling water flows through the side cover housing, which is most affected by the heat transfer from discharged air at the outlet side. By preventing large temperature increases in the side cover housing, the bearing holders also experience less heat exposure. Furthermore, when maintaining the flow of cooling water through the side cover housing itself, ITO succeeded in improving the efficiency and service life of the bearings, oil seals, O-rings, and lubrication oil.
(1) Bearing temperature is below 75℃. ITO bearings have long service life of at least five years.
(2) Lubrication oil change intervals range from 2000 operating hours to 8000 operating hours due to favorable viscosity.
(3) Oil seal, O-ring etc spare parts: J-type blowers can cool down the bearing holder, which can prolong the service life of the Oil seal, O-ring etc spare parts installed in bearing holder.
