Key Features
- Low noise level, less operating power required
- Improved volumetric efficiency & reduced operating temperatures
- Alloy steel timing gears
- Cylindrical roller bearings
- Piston ring air seals
- Hydrodynamic shaft seals
- Splash oil lubrication
Benefits
- Durable Construction: The ROOTS® RAS-VJ blower features grey iron headplates, gear cover, drive end cover, and one-piece casing, along with carburized alloy steel spur timing gears taper mounted on the shafts, secured with a locknut. Cylindrical roller bearings ensure robust performance.
- Efficient Sealing Mechanisms: Piston rings and lip-type oil seals minimize air leakage and prevent lubricant from entering the air chamber, with a hydrodynamic seal on the drive shaft preventing oil leaks.
- Effective Lubrication: VJ whispair vacuum exhausters incorporate splash oil lubrication at both ends for smooth and reliable performance.
- Versatile Shaft Options: The top shaft is extended for drive on side outlet vacuum exhausters, and the left or right shaft can be extended for drive on bottom outlet vacuum exhausters.
- Water Injection System: An inlet spray nozzle and seal water flow meter are supplied for water injection, enhancing pump efficiency.
- Warranty Coverage: A warranty period of 12 months from date of original unit start-up or 18 months from date of original shipment is provided.
