Air Purge Designs

By changing the seal environment, even the most challenging applications can
be reliably sealed.

• Dramatically improve the equipment life in
demanding applications
• Prevent contamination across the seal
• Maximize reliability with no heat generation, vibration or lubrication

The LabTecta 66OAP is specifically designed for
®
use in extreme environments and applications where
contamination may completely cover the
seal / equipment. The unique design uses a positive
air purge to enhance the performance of the labyrinth,
with AESSEAL mechanical seal pressure balancing
®
technology to maximize the performance of the seal
and minimize air consumption.
