Keystone Blade

Increase In Airflow

Keystone RV Company is introducing an entirely new air handling system designed to significantly improve air conditioning performance. In initial testing, Keystone Innovation Lab engineers saw an average air flow increase of more than 20%.

Recognizing that there was a disconnect between new high-output air conditioners and the systems used to distribute cooled air throughout the RV, Keystone’s Innovation Lab team leveraged core fluid dynamics principles to redesign the system. Elbows and wyes with larger intake openings that taper into the ducting both reduce air turbulence and increase cold air speed throughout the full length of the ductwork. Blade introduces a new vent design that uses negative pressure to drive air flow into the cabin. The Blade vent diffuser eliminates hot and cool spots by distributing cold air in a circular pattern and setting up natural convection throughout the coach. Lastly, the Blade system eliminates the reliance on foil tape alone by adding injection molded components at each joint in the system. Keystone is the first company in the industry to do this.

  1. I have a 2021 Keystone Cougar 24RDS, VIN.# 4YDF24R29MV503564.
    All the descriptive litature, brochures, and videos show this 5th wheel with the “Blade” Diffusers in the ceiling of this model. However my Mdl. 24RDS has the “Old Diffusers” in the ceiling.
    My question is why doesn’t it have the “Blade Diffusers”?
    Thank You
