· Large compensation rate: multi-dimensional compensation by one compensator.
· Counter thrust free:      The compensator can absorb the expansion from the prior

bellow unconditionally  without transfer to the bellow follows because of its softness. Resistance to elevated temperatures and erosion: the materials concerned such as silica gel fabric, fluorine gel fabric, Teflon have the property of good resistance to high temperatures and erosion.

· Soundproofing and shock isolation: The non metal material such as the fabric owns the

property of Soundproofing and shock isolation which can reduce the noise and shock of the boiler and the fan.

· Compensation for the alignment error.
· Good air tightness.
