Drimaster 2000
The Drimaster 2000 is the UK's leading low cost, low energy positive input ventilation unit.
The Drimaster provides whole home ventilation using the Positive Input Ventilation principle. Essentially the concept is to introduce
fresh, filtered air into the dwelling at a continuous rate, encouraging movement of air from inside to outside.
To achieve this, the unit is mounted in the loft space, drawing air through the filters and inputting it, at ceiling level, into the property.
The Drimaster units are supplied with a remote temperature sensor that works in conjunction with the units internal sensor. This sensor
continuously monitors the temperature in the loft and house, boosting the air volume when the loft temperature is greater than the house (heat recovery mode).
If the loft temperature becomes excessive the unit will switch to standby mode (no airflow). Once installed, the airflow can be set to
suit the house size and, if required, the way it responds to the temperature changes within.

Intelligent 4 way heat recovery
- Solar gain in your loft.
- The expensive heat from your home heating system that passes through the loft insulation.
- The unique Drimaster diffuser that re-circulates the heat at ceiling level on your landing.
- The patented, intelligent heat recovery system that will boost the fan when the temperature in your loft is greater than that in your home (in the heating season).
5-year life filters
- Huge filters (0.47 sq.m) that only need replacement once every 5 years.
NB: There is no other maintenance required. - G4 grade, which means that they are so fine they will even, exclude pollen; great for hay fever sufferers.
Net energy gain
- Fan uses only 5 watts of electrical power (on average).
- GAverage energy gain approximately 100 watts of heat.
Whisper quiet
- For most of the time it is unlikely that you will hear or be aware that your Drimaster 2000 is operating.
6 speeds to choose from
- House sizes and occupancy levels vary so your Drimaster 2000 can be adjusted to exactly suit your home.This will ensure that it will always match your needs.
Easy non-disruptive installation
- Your Drimaster 2000 is fitted in the loft, out of sight, no holes to knock through walls or new glass for windows. Your installer will need to fit the diffuser in your ceiling (usually on your landing). All this usually takes just a couple of hours.
Automatic cut off when the temperature in the loft becomes excessive
- During sunny months the temperature in your loft can be excessive. At this time of year it would be uncomfortable to bring this heat into your already warm home. Your Drimaster 2000 will sense this condition and automatically move to standby mode. The unit will start again automatically when the temperature reduces to an acceptable level.

Frequently Asked Questions
- What is a Nuaire Drimaster Whole House Ventilation Unit?
It is a small, loft mounted, low energy air clearing/moving device that continuously inputs filtered fresh air into your home from outside. The only ‘visible’ component when installed is the central input diffuser, which is usually located in the central hallway/stairwell ceiling.
- What does the unit do?
The unit will cure and/or prevent the problems associated with condensation dampness in your home, providing a healthier living environment for all occupants. The unit will prevent mould growth on walls, ceilings, furniture, clothes and curtains. The unit also eradicates the musty smells evident in homes with severe condensation problems.
- How does it work?
Simply and very efficiently. Outside air is drawn into the loft where it is slightly warmed by the free heat in the loft caused by solar radiation and the heat lost from the property into the loft. This air is drawn into the unit, filtered and then ducted into a central area (typically the hallway/stairwell) of the dwelling which mixes with the warmer air that naturally accumulates at ceiling level. This tempered, fresh, clean air then continuously and gently dilutes, displaces and replaces the air within your home. The result is a home with a more pleasant and comfortable environment, free from condensation and dampness.
- How much does it cost to run?
The electrical consumption will be around a penny a day. When considering the advantages the unit will provide you and the other occupants, the running costs are insignificant and it should be remembered that the unit is making use of heat in both the loft and at ceiling level that would otherwise be lost.
- How do I operate the unit?
You don’t. The unit is completely automatic, switching from ‘normal’ to ‘boost’ and ‘off’ as required to make optimum use of energy. (Boost facility is only available on the Drimaster 2000 unit).
- What maintenance is required for the unit?
Very little. The only maintenance required is the replacement of the filters every 5 years. We do recommend that a full service is carried out every five years please contact our Customer Service Team for further information on 08705 002 555.
- How will I remember to clean the filters?
The remote sensor (2000 units only) has a led, which will flash red after a, five year period to indicate filters need to be replaced.
- How will I know if the unit is working?
The unit motor may be almost inaudible but you should notice a change of atmosphere in the hallway within a day or so. Within a few weeks any mould should start to dry out eventually becoming a grey powder which can be easily wiped clean. After 60 days your home will be a healthier environment free from severe condensation dampness.
