The PowerStream® airflow straighteners, standard equipment on EX and GX models, was the first flow straightening technology on PPV fans, increasing flow velocity and effective range of the FlowPath™, allowing more flexible setback positioning.
PPV with PowerStream is like going from a fog nozzle to straight bore.
This allows setback distances to increase five fold.
Both PowerStream and
conventional fans can
operate in close range of
Only PowerStream fans
can be set back as far as
18ft (5.4m) and be equally
Polymer TurboForce™ impeller is engineered
to deliver maximum airflow.
Designed to perform better when set back from 6’ to 18’ (3 to 6 meters) rather than directly in the structure opening.
Greater setbacks mean uncluttered ingress and egress for greater safety.
Noise inside the structure is reduced for improved communications.
RAMFAN can provide documentation for fans included in AMCA’s Certified Ratings Program. Click here to see our rated fans on the AMCA.org site.
AMCA 240 is the only third-party published PPV testing method assuring the end user of an accurate performance comparison.
An AMCA test report includes airflow, horsepower and distance from the opening.
RAMFAN provides several AMCA tests for each blower which define the performance zone.
