Flexible Installation




Rapid Installation

The compact size of the unit and its unique spigot configuration allows easy installation into any vertical or horizontal application and is ideal for restricted spaces. With up to nine spigot connection points the unit offers optimal versatility.

The easy push button commissioning pad enables the installer to correctly set the required airflow rate quickly and effectively.

Intelligent Humidity Tracking

The system continuously operates at a low level to ensure that the home is correctly ventilated, providing all year round good indoor air quality. Incorporated within the MEV Spider is the intelligent humidity tracking controls as standard, which constantly monitor the humidity level, meaning no user intervention is required. As humidity rises and falls, the motor speed rises and falls in direct correlation. This controls condensation quietly and efficiently, reducing the periods of time when the system operates on maximum speed, saving energy.

Control Options

The MEV Spider is supplied with a remote controlled boost switch as standard offering ultimate control to the user. The unit is fully commissionable to high and low rates to ensure optimum performance and efficiency.
