The conservative load carrying capacity of the larger diameter bearings ensures an extended operating life. Timing gear life is also extended by a controlled lubrication system.
The computer calculated impeller profiles ensure maximum volumetric efficiency with minimum absorbed power without sacrificing torsional rigidity. The high rigidity of the impeller and generous shaft diameter keeps stresses low.
Gear and shaft strength is substantially increased by the use of slow taper mounted gears which do not need keyways for location. This also simplifies the setting of the gear wheels to obtain correct timing of the impellers, a feature that facilitates field maintenance.

Precision ground and hardened steel gears are used to ensure smooth running and accurate timing of the rotating impellers. Specially designed rotary oil seals are used in the gearcase.
This feature eliminates maintenance associated with the use of lip seals. This range can now be supplied with oil lubricant at the drive end as well as the gear end and thus helps to simplify maintenance.
This feature is particularly attractive where the blower is used in high ambient temperature conditions.

Design and manufacture is in accordance with metric standards.

We can integrate your system with hydraulics as well as power take off units (PTO).

CASING: The cylinder and headplates are manufactured from cast iron. The gearcase is manufactured from aluminium.

IMPELLERS AND SHAFTS: The impellers are made from SG iron, and cast with integral shafts. The shaft diameter of machines in the HRBV (RBTM) Blowers range is larger than that of earlier designs, enabling increased operating pressures to be achieved without increasing blower size. GEARS: The precision ground and hardened steel spur gears are taper mounted onto the impeller shafts. The timing of the impellers relative to each other is accurately maintained at all times.

BEARINGS: The bearings are of generous proportions to give long operational life. Grease or Oil lubricated double row ball bearings are used at the drive end of the blower. In addition to their normal duty of carrying radial loads associated with the differential air pressure on the rotating impellers, the ball bearings provide axial location of the impellers. Parallel roller bearings at the gear end are splash lubricated by oil from the gears.

LUBRICATION: Our design of controlled gear wheel lubrication enables the gears to operate at a high pitch line velocity without the need for an oil pump. Simple, maintenance free oil throwers fitted behind each bearing in the gearcase prevent leakage of oil. The drive end is grease lubricated but oil lubricant is now available making the unit all oil lubricated and eliminating grease requirements.

DIRECTION OF ROTATION: Standard machines have a right hand drive shaft for vertical air flow, and a bottom drive shaft for horizontal air flow. If machines are required with a left hand or top drive shaft, all that needs to be done is turn the gearcase and trough through 180º.
