Features
- Completely airtight using dual airtight structure (air chamber); even if a leak occurs due to damage to components on the inside, second airtight structure prevents dispersion of dust until maintenance or servicing is performed
- Double airtight structure through Gland-Packing and Lip-Seal; lubricant oil also helps to maintain airtightness for a complete seal
- Lubricating effect reduces friction by 30% or more, and wear damage of parts by 50% or more
- Leaks prevented fundamentally by airtight structure comprising dual air chambers, Lip-Seal and lubricant oil

Utility
- Pressure acts from inside the tank to outside
- Wear of Gland-Packing causes frequent leaks of dust, making maintenance and servicing difficult
- Replacing equipment where wear dust causes wear of Screw and Shaft, shortening the lift (Sleeve around the worn area of the shaft can be replaced or repaired)
