EnviroVent PIV LoftVent Mk2 Positive Input Ventilation Units
The EnviroVent Loft Mounted PIV (Positive Input Ventilation) Unit is a sophisticated whole house ventilation and condensation control unit for homes with a loft space. The PIV unit gently ventilates the home from a central position on the landing in a house or the central hallway in a bungalow to transform a stagnant and stale atmosphere into a fresh, healthy and condensation free environment.
