EnviroVent Launches Silent Dual Extractor Fan

EnviroVent, one of the UK’s leading ventilation manufacturers, has introduced a new autonomous and intelligent extractor fan into its renowned SILENT range, ideal for bathrooms and WCs. 

Simple and straightforward to install, the SILENT DUAL 100 offers dual functions, dual sensing and dual inlets, which make it one of the most versatile and innovative extract fans available, backed-up with a full 5 year warranty. 

The SILENT DUAL 100 automatically adjusts its performance according to the environment and ventilation requirements, via two sensors: a presence detector and a humidity sensor, making it ideal for applications such as care homes and communal residences. It also features EnviroVent’s innovative Silent motor block for quiet running. 

Rory Percival, Head of R&D and Technical for EnviroVent, explains: “This is a major development, which brings a versatile fan with low energy consumption, low noise levels and good aerodynamic performance.  We are driving forward with innovation in ventilation technology to ensure installers can offer their customers the most efficient indoor air solution.” 

The innovative Dual Sensing function of the SILENT DUAL 100 means the fan operates automatically when it detects movement (via the PIR) or a rise in humidity levels. This activates a preset mode to achieve the lowest energy consumption and the lowest noise level.  

Designed with versatility in mind, the Dual Function facility allows the fan to be programmed in intermittent or continuous running mode.  

In both operating modes, for smaller changes in humidity, the fan incrementally increases the airflow rate until the humidity level has fallen below the set threshold, ensuring quiet and efficient operation. For larger changes in humidity, the fan reacts accordingly to this change in its environment and operates at full speed. 

The SILENT DUAL incorporates an intelligent algorithm to automatically adjust its settings according to the environmental conditions, without the need for user interaction. The motor is commissioned to achieve the required flow rate, minimising the electricity consumption and noise levels to meet the exact ventilation requirement. 

The SILENT DUAL 100 is designed to operate with very quiet noise levels, suitable for WCs and bathrooms and can be installed in Zone 1. The fan has been designed to operate in either intermittent or continuous running mode with a PIR detector, humidity sensor, backdraft shutter and airflow guide vanes as standard. 

The SILENT DUAL 100 can be wall or ceiling mounted to meet Building Regulations – Part F (England), Scottish Building Standards and Part K (Northern Ireland). 

EnviroVent offers a range of Positive Input Ventilation (PIV), Mechanical Extract Ventilation (MEV) and Mechanical Ventilation with Heat Recovery (MVHR) solutions to the new build and refurbishment sectors. Its award-winning products are UK manufactured and can be installed by its own dedicated team of nationwide installation engineers, who also provide after-sales support.
