Damp Pro

Whole House Ventilation System

The Damp Pro Unit is a sophisticated whole house ventilation and condensation control unit for homes with a loft space. The 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.

How it Works

Phase 1

Shortly after the unit is installed the unit gently ventilates the home with fresh, filtered air. Air is pushed back down into the house and redistributed. Humidity starts to be diluted and replaced.

Phase 2

Anytime from 48 - 72 hours later the air in the home will start to feel cleaner and fresher. The air from the unit transforms a stagnant, stale atmosphere into a fresh, healthy and condensation free environment.

Energy Saving Benefits

Minimum Energy Consumption

Powered by an Ultra Low Watt Brushless DC Motor, the Damp Pro utilises the latest technology to ensure minimum energy consumption and long term trouble free life.

Solar Gain

The unit takes maximum advantage of the benefits of solar gain from within the loft space - the natural accumulation of heat from the sun on bright days. Temperatures in the loft space are on average 3°C higher than outside, which results in a relative saving of around 150 Watts per day in an average modern family home. This equates to approximately 10% of annual heating costs.

Heat Distribution

Warm air accumulates at ceiling level. This air can be up to 7°C higher than the air at ground level. By introducing an almost imperceptible air supply into the dwelling from the loft space, the Damp Pro Unit helps to redistribute heat around the home and thus reduce space heating costs.

No Need to Open Windows

To reduce humidity and condensation during the heating season, significant energy loss occurs by opening windows. By installing a Damp Pro and providing fresh filtered air to the home, humid air is displaced without opening windows and thus making significant savings to the occupier.


Sited in a loft space, the unit delivers air to the central hallway or landing via a four-way diffuser with purpose made blanking plates to maximise efficiency of airflow and aid in heat recovery from ceiling level. This provides displacement ventilation in order to improve air quality and resolve condensation related problems.


Incorporates the Ultra Low Watt DC motor technology with sealed for life ball bearings designed to operate continuously at a pre-set ‘background’ rate.


Is a 140 x 220mm centre mounted forward curved centrifugal fan.


Is a synthetic fibre based filter mat to G4 standard in accordance with EN779 standard ratings, conforming to all European Union and US fire classification standards (e.g. DIN 53438-F1 and UL900-class 2) and be self-extinguishing.


Achieved by exchanging filters and consumable items. There should be no requirement for any maintenance within the five year period.

Integral ‘Intelligent Low Temperature’ Comfort Heater

Powered by a single supply and capable of holding incoming air temperatures accurately – around 10°C. The integral heater element is manufactured in a solid tubular sheath material and not in open wire format.

Question & Answers

How do I adjust loft PIV settings?

The units are designed to be set up according to the requirements and environment, however settings can be altered if required, depending on the system installed. Refer to the manual for individual units.

How does my anti-condensation heater enable switch work?

When enabled, this will enable the automatic function of the comfort heater. The Heater will only be activated when the temperature is below 10°C in the loft unit.

How much does the unit cost to run?

The units use very little energy, in normal running the unit will use less than 15 watts of energy. With the heater enabled and temperature below 10°C then these running costs will increase. The energy consumption will increase; however it is estimated the heater will only be on 10% of the time as the comfort heater pulses to maintain a temperature of 10°C. when mixed with the internal air at ceiling level and distributed around a dwelling, this should help reduce energy costs within the dwelling.

I have a loft unit installed, why is my hallway a different temperature to the rest of the house?

The unit is designed to ventilate from a central location. The air entering the property will always be cooler than the rest of the dwelling, however as this mix’s with wasted heat at ceiling level and recirculates around the dwelling this can save energy while ensuring good indoor air quality. Keeping all internal doors closed will ensure you get the full benefits from the system. Cold drafts can be felt if the air is blowing directly on to a wall or into a habitable room.
