Systemair’s Innovative New AJR-Q Axial Impulse Jet Fan Significantly Reduces Noise While Improving Performance

Reading Time: 2 minutes

The AJR-Q is the newest addition to Systemair’s AJR Series of Axial Impulse Jet Fans, which are designed to optimize Sweep Ventilation Systems and reduce costly exhaust ducting in enclosed and underground parking garages. Using the combined performance factors of Airflow, Thrust, Throw, and Induction, the AJR fully implements an Extraction Ventilation Strategy to more effectively reduce CO levels compared to traditional garage ventilation designs.

The new AJR-Q addresses the most common challenge of Axial Jet Fans by reducing objectionable fan and airflow noise while improving performance. The innovative design increases airflow and thrust while achieving up to 9% reduction in sound pressure (dB, LpA) measured at 10’ distance.

Key differentiators include significantly lower sound levels while also dramatically increasing CFM and thrust.

“The ARJ-Q series from Systemair is the result of our continued investment in R&D for car park solutions.” said Ivan Daza, P.Eng., Product Manager for Systemair. “We are pleased with the quietness of the AJR-Q. The -7 dB change in sound pressure level of the AJR-Q 355 is essentially cutting in half (55% reduction) the perceived sound volume to the human ear. The  -4 dB of sound pressure level of the AJR-Q 400 is about a 35% reduction in perceived sound volume.”
