PP-50 Power-Plume®

Power Plume

U.S. Patent No. 8,672,614

The Power-Plume was designed for critical lab applications where safety and efficiency are the primary concerns.

Power-Plume is a powered induction device used to induce large amounts of ambient air and generate plume height regardless of the lab exhaust flow. This device has the unique advantage of maintaining a minimum 50 foot plume height even as the lab exhaust flow is reduced for partial load conditions. Dilution rates at maximum lab exhaust flow exceed 200%. As the lab exhaust is reduced, dilution rates can exceed 1,000%.

Power-Plume conveys a column of ambient air around the lab exhaust air encapsulating the contaminated lab exhaust. The primary lab exhaust fan is still utilized to exhaust the contaminated lab air. It can now be operated on a VFD for partial load conditions. This saves energy as we no longer need to utilize bypass air during partial load conditions to maintain plume height. Since the primary lab exhaust fan is not required to generate the high discharge velocities for adequate plume height, the power requirements of this fan are significantly reduced.
