Elektrovent EBACK A and ESIR centrifugal fans: tailor-made solutions for every system

Elektrovent centrifugal fans for high flow rates: EBACK A and ESIR, two complementary solutions for ducted systems

In HVAC and industrial systems, managing large air volumes requires reliable, high-performance solutions designed to adapt to different operating conditions. Elektrovent's EBACK A and ESIR centrifugal fans , also featured at MCE, fit this bill. They are designed for ducted applications requiring high flow rates and low pressures.

Two complementary lines that share a solid design foundation, but which differ in their aerodynamic configuration and application areas, thus offering a targeted response to the most diverse design needs.

 

EBACK A centrifugal fans: efficiency and performance with backward curved blades

The EBACK A series represents the ideal solution when the objective is to maximize energy efficiency while maintaining high air flow rates .

The heart of the system is the high-efficiency backward-curved impeller, a design choice that allows for more efficient performance than traditional configurations, while simultaneously reducing energy consumption.

From a construction point of view, EBACK A stands out for its robust painted steel structure and a design validated by in-depth tests in the test room, which guarantee its reliability over time even in harsh environments.

Typical applications include industrial and commercial environments, parking lots, marine applications, and even mining, where continuity of operation and stable performance are essential.

Another key element is installation versatility: the ability to configure accessories such as anti-vibration joints, flanges, and protective mesh allows the fan to be adapted to different system configurations, improving integration and durability.

 

ESIR centrifugal fans: compactness and reliability with forward-curved blades

Alongside the EBACK A series, Elektrovent offers the ESIR line , designed for applications requiring high flow rates with low pressures, but with a different configuration.

In this case the impeller has forward-curved blades, a solution that favors the management of large volumes of air in ducted systems, maintaining good operational stability even in variable conditions.

The ESIR series stands out for its solid construction and a design optimised through performance tests , capable of achieving efficiency levels often higher than market standards.

Of particular interest is its ability to adapt to a variety of application contexts: from residential and industrial systems to restaurants, parking lots, and marine applications. This flexibility makes it a versatile solution for designers and installers.

From a technical point of view, the range covers various sizes with impeller diameters up to 450 mm and also allows for use in more demanding conditions, with versions that support air temperatures of up to 100°C for specific models.

 

Two solutions, one goal: to adapt to the system

When viewed together, the EBACK A and ESIR series clearly highlight Elektrovent's strategy: to offer complementary solutions to cover all high-flow ventilation needs.

The choice between the two depends mainly on the system configuration and the required performance:

  • EBACK A is oriented towards energy efficiency and performance, thanks to the backward blades
  • ESIR favours simplicity and management of large volumes, thanks to the forward blades

However, both series share fundamental elements: robust construction, a wide range of accessories, compliance with regulations and the possibility of customization upon request, such as stainless steel versions or special configurations.

 

Performance and design: the value for designers and installers

A central aspect of both lines is the precision in aeraulic design , supported by detailed performance diagrams (flow rate, pressure and noise) and tests compliant with international standards.

As highlighted in the technical diagrams in the catalogues, performance figures refer to standard conditions (air at 15°C and sea level), allowing designers to make reliable sizing decisions consistent with actual conditions of use.

This approach allows fans to be integrated precisely into the system , avoiding oversizing or inefficiencies.

 

Elektrovent and high-performance ventilation: two series, one goal

The EBACK A and ESIR series from Elektrovent represent two complementary interpretations of high-capacity ventilation: on the one hand the optimised efficiency of backward-curved blades, on the other the versatility of forward-curved blades.

Two solutions designed to meet the real needs of civil and industrial systems, ensuring reliable performance, installation flexibility, and operational continuity over time.

FAQ

I ventilatori EBACK A ed ESIR trovano applicazione in impianti HVAC e industriali dove sono richieste elevate portate e prevalenze importanti. Sono particolarmente adatti per unità di trattamento aria, sistemi di ventilazione industriale, estrazione fumi e processi produttivi, soprattutto in presenza di reti canalizzate complesse o condizioni operative gravose.

La scelta di una configurazione su misura è indicata quando le condizioni di esercizio escono dagli standard, ad esempio per esigenze specifiche di portata, pressione, temperatura o materiali. Questo approccio è particolarmente efficace nei retrofit impiantistici, nelle integrazioni OEM e in ambito industriale, dove è fondamentale garantire continuità operativa e perfetta compatibilità con il sistema esistente.

Le serie EBACK A ed ESIR consentono di gestire grandi volumi d’aria con elevata efficienza, adattando la curva caratteristica alle reali esigenze di progetto. La robustezza costruttiva le rende idonee a funzionamenti continuativi anche in condizioni variabili, contribuendo a migliorare il rendimento complessivo dell’impianto e la stabilità operativa nel tempo.

Rispetto ai ventilatori assiali, queste soluzioni centrifughe garantiscono prevalenze più elevate e risultano più adatte per impianti con canalizzazioni articolate. Inoltre, la possibilità di personalizzazione progettuale consente di rispondere in modo più preciso a vincoli tecnici e condizioni critiche, dove soluzioni standard potrebbero risultare limitanti.

In fase di progettazione è fondamentale considerare il corretto dimensionamento rispetto alle perdite di carico dell’impianto e la piena integrazione con canalizzazioni e componenti accessori. Occorre inoltre prevedere adeguati sistemi di isolamento da vibrazioni e rumore, garantire la compatibilità con sistemi di regolazione come inverter o BMS e assicurare un’adeguata accessibilità per le operazioni di manutenzione.

I ventilatori EBACK A ed ESIR permettono di affrontare in modo efficace la gestione di elevate portate in impianti complessi, migliorando l’efficienza energetica e superando i limiti di soluzioni non ottimizzate. Consentono inoltre una più semplice integrazione in sistemi esistenti e garantiscono affidabilità anche in ambienti industriali severi, riducendo le criticità legate alle alte perdite di carico e alla continuità operativa.
