    Mechanical Extract Ventilation (cMEV)

    The PHS MEV-H unit from Passive House Systems is an SAP approved, low-energy, continuous mechanical extract ventilation system designed with multiple extract points to simultaneously draw moisture-laden air out of the wet rooms, whilst minimising the migration of humidity to other rooms.

    Humidity Controls

    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 unit is the variable humidity control as standard, which constantly monitors 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 at maximum speed, saving energy.

    Design and Supply

    We will design and supply a whole house/apartment extract system that will provide continuous renewal of the air and meet building regulations. We have a large range of MEV & HRV machines, pipework, and accessories to choose from.
