Designed to provide the optimum amount of air volume needed for efficient pneumatic unloading of bulk trailers, allowing more airflow, less back pressure and higher unloading rates.

3-port assembly

• Durable, food grade silicone resists hardening, cracking or tearing
• Robust design does not have snap retention legs that can break off or flimsy disks that crack and wear prematurely.

• Seals completely to hopper or wear plate to stop the back flow of product into the aeration lines, even when flood loading.
• If used to haul abrasive products like sand or cement use hopper savers to protect from wear on the aluminum hopper.
