KUVIO & KUVIO-Q

The quietest in-duct helicocentrifugal fans on the market are called KUVIO-Q

These are low-profile helicocentrifugal fans designed for inline installation, featuring ultra-quiet operation and high energy efficiency.

Within their category, they are the quietest on the market and hold IMQ certification, ensuring their sound levels, performance, and electromagnetic compatibility.

 

FEATURES

High-Strength Plastic Casing

The fan casing is made of durable plastic with a microperforated ogival core and flow-straightening blades to minimise turbulence issues. These characteristics make them particularly quiet, ideal for spaces requiring low-noise operation, such as offices, waiting rooms, meeting rooms, libraries, and residential areas.

Energy efficiency and compliance

With high energy efficiency levels, they comply with the requirements of EU regulations ERP 327/2011, ERP 1253/2014, and anticipated future updates. The KUVIO-Q and KUVIO-Q EEC fans are distinguished by their high performance, low power consumption, reduced noise emissions, and ease of installation and maintenance.

Easy maintenance

Maintenance is exceptionally straightforward due to the absence of fibres or mats in the equipment’s insulation.

 

MANUFACTURING FEATURES

Injection-Moulded Technopolymer Casings

KUVIO-Q fans feature casings made from injection-moulded technopolymer, certified for fire resistance class E2 in compliance with EN ISO 11925-2:2010. They also boast a high level of water ingress protection (IP45).

Electrical Box

The electrical box is crafted from plastic, ensuring electrical and fire resistance.

 

FAST MAINTENANCE AND LOW-PROFILE DESIGN FOR TIGHT SPACES

The central core, equipped with circular outlets at both ends for duct connections, can rotate around its axis, facilitating installation in tight spaces and simplifying wiring and maintenance.

The unit’s easy disassembly—without altering the duct system—speeds up and simplifies maintenance. Simply release the clamp tabs to separate the fan body from the inlets and remove it from the duct. Once the screws connecting the two halves of the casing are removed, the insulated fan core is accessible. Reassembly is equally simple, requiring no additional components, and maintaining the tested noise levels.

 

MICROPERFORATED CORE AND HELMHOLTZ RESONATORS

The ogival core corrects airflow after passing through the turbine. Together with the flow straightener, it prevents energy losses caused by turbulence.

The microperforations, combined with Helmholtz resonators, reduce noise at predetermined frequencies.

 

KUVIO-Q VERSION

  • KUVIO-Q fans are available with traditional AC induction motors featuring three speed settings, thermal protection, and shafts mounted on ball bearing supports, paired with centrifugal impellers.
  • Sizes 100, 125, 150, 160, and 200 are also available with adjustable timers.
  • Nominal diameters range from Ø100 to Ø315 mm.
  • Airflows up to 2,900 m³/h.

 

KUVIO-Q EEC VERSION

  • The KUVIO-Q EEC version features electronically controlled brushless EC motors (low energy consumption). Each speed can be configured during installation. Alternatively, the units can operate at a single speed, adjustable via a 0-10 V signal.

  • Nominal diameters range from Ø100 to Ø315 mm.

  • Airflows up to 2,600 m³/h.
