Introduction

This Rotary Heat Exchanger Seal Brush—also known as a Thermal Wheel Seal Brush or Energy Recovery Wheel Seal Brush—is for sealing around the circumference of rotary heat exchangers. It can minimize air leakage between the rotor and housing, thereby improving thermal efficiency and overall energy recovery performance.

    It features pre-slotted mounting holes for quick adjustment.
  • High-Density Yarn with Elastic Fin
    The yarn is stitched along its length and divided by a transparent elastic fin in the center.

The yarn material is available in silicone-treated polyester for water resistance, and includes 2% UV protection, making it suitable for long-term use in HVAC systems.

? Installation Tip:

To extend the product’s service life and prevent yarn from unraveling, we recommend lightly burning both ends of the yarn with a lighter at the start and end of installation. This helps fuse the fibers and keeps the brush structure intact over time.
