Integral bearing isolator
The BRS Labyrinth Air Shaft Seal is an engineered pneumatic sealing system designed to seal the shafts of machines where typical contact seals such as packing and/or mechanical face seals prove to be ineffective.
It uses a small amount of air or gas to create a positive pressure along the shaft, preventing power particles leaking and keeping the pollutants out.
Application： Mixer, Screw Conveyor, Blower, Extruder,
Agitator, Blender
Features & Specification:
Efficient design minimizes air usage while maintaining internal sealing pressure profile
The only design to accommodate shaft deflection, run out, axial displacement and misalignment
Split design are available for easy installation
Requires little or no maintenance after installation
Can be custom designed to fit your specific application
Maximum Shaft Speed: 30m/s
Temperature Limit：-35oC~210oC
Maximum Shaft Runout：7mm
Maximum Shaft Axial Movement：15mm
Materials: Stainless Steel, Bronze, Aluminum Alloy, Filled
PTFE, PEEK, FKM rubber
Soft-face Air Assistant Seal
Soft-face Air Assistant Seal chooses filled PTFE or PEEK as the rotor, FKM or EPDM rubber as the driving ring, and the stator are made of stainless steel. The rotor and stator are maintain in contact during operation, remaining the materials handled in and keep pollutants out. This special system uses compressed air to assistant sealing power material and cooling the contact sealing face, offer excellent performance.
