Data showing the low-noise operation of ShinMaywa helical blowers

Reliable oil seal

    Fluorrubber is used for the oil seal. The lubricating system is protected by a labyrinth seal which is effective in preventing oil leakage. 

Easy maintenance

    The bearing is fixed with a C-type retaining ring. The timing gear can be disassembled easily using a gear puller. A ball bearing is employed instead of a roller bearing, to avoid damaging the inner case during reassembly. This simplifies blower maintenance significantly.

Improved durability

    The blower durability has been improved through the use of a larger bearing and the lowering of motor speed, as well as the reduction of temperature rise.

Variable Frequency Drive (VFD) controlled air flow rate

    VFD control system permits the motor speed to be easily changed electrically. When VFD control is used

with the blower, the air flow rate can be varied freely. Also, by using a suitable control device with the blower, it is possible to implement automatic control of the blower. (The range within which motor speed can be controlled depends upon blower operating conditions. When using a VFD with the blower, consult your nearest dealer.)

※ The VFD used should be a constant torque type.
