Quiet Fan technology (QFt)

Industrial fans and blowers are notorious for generating persistent tonal characteristic, such as low frequency hums and drones. These specific tones can travel very long distances, transmit through building structures, and are the number one cause of environmental noise complaints.

When facing these issues, the traditional approach tends to rely on massive silencers / attenuators or large heavy enclosures. However, treating the symptom rather than the cause comes with a hidden tax.

These conventional palliatives can restrict airflow, creating backpressure that hits the fan efficiency and drives up energy bills. They clog easily in dirty environments, require ongoing maintenance, and need days (or weeks) of operational downtime to install - not to mention the costs of installing such measures!

There is a fundamentally better way to reduce noise tonal noise from fans. Instead of building massive structures to contain the noise after it has already been created, our Quiet Fan technology (QFt) tackles the noise being generated at the source.

QFt uses custom designed inserts fitted directly inside the existing fan casing to smooth out pressure pulsations at the blade passing frequency (the cause of the tonal hums and drones). It is a quiet revolution in noise control: a permanent, aerodynamic solution that silences the fan without the silencer, simultaneously reclaiming your system's efficiency.

By shifting the focus from containing noise to optimizing aerodynamics, QFt delivers a definitive answer to fan noise:
