Type RT TURBAIR® vacuum blower.
Resource-efficient and cost-saving dewatering
The sustained success of the single-stage TURBAIR® is based on a number of factors:
- Compared with traditional water ring pumps, a TURBAIR® blower from the RT series requires only about 45-55% of the absorbed power.
- The volume flow changes depending on the age of the felt: the air volume requirement is controlled automatically by diffusor blades regulation. The aim is to achieve consistent dewatering over the felt.
- The RT has a frequency-controlled drive: the vacuum may be adjusted to a wide range of tissue weights and types.
- TURBAIR® blowers do not require seal water, so no fresh water and no cooling tower is required.
- Vacuum blowers have no wearing parts, making them dependable and maintenance-friendly.
- The base frame for the RT series bolts straight to the floor, resulting in a very compact design.
- The efficiency of the water separation process has seen considerable improvement in recent years, making it possible to extend the cleaning intervals for the concrete or steel separator.
- The blower exhaust air can be sent to a heat exchanger (from single- to three-stage), which discharges the blower at a temperature of 120-130°C and thereby recovers up to 70% of the absorbed energy.
“In combination, these benefits result in a simple return-on-investment calculation for our customers: the amortization time of a TURBAIR® system of this kind, installed in an existing paper production mill, is less than two years,” says Manfred Dobler, Head of Paper Industry at MAN Diesel & Turbo.

A large number of satisfied sanitary paper producers confirm the successful use of TURBAIR® blowers in tissue manufacture and show that huge cost savings can be made on paper dewatering.
