Condensation is becoming one of the commonest causes of dampness in buildings and is nearly always associated with black mould growth (Aspergillus niger).
The problem arises because of high relative humidities, a lack of natural ventilation and, in most cases, cold external walls. Sometimes it's possible to reduce humidities by regulating activities like drying clothes indoors. Ventilation can be provided via trickle vents and so on but these are usually ineffective and unpopular due to perceived heat losses or cold draughts. Walls can be insulated but not without relatively major disturbance to occupants. Because of these factors a new approach to providing energy efficient humidity control was needed and this has been provided through the concept of positive input ventilation.
Wykamol are stockists of a wide range of energy efficient, low maintenance fans which can be fitted with little or no disturbance and provide dramatic improvements to indoor air quality. They operate fully automatically and can transform 'mouldy' rooms in houses within a few days of installation. Many of our approved contractors are able to offer a full diagnosis and installation service and will ensure you get the system best suited to your property.

SPECIFICATION WIRING DIAGRAM

NU-AIRE DRIMASTER 2000 - 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.
Features & Benefits
- Complies with Building Regulations Ventilation requirements and contributes towards ‘conservation of fuel and power’. (Please refer to BBA Certificate 00/3727 for full details).
- Extremely low power consumption – average approximately 0.16 watts/litre/second.
- Fully automatic with ‘Intelligent Heat Recovery’.
- Very low maintenance requirement (filter replacement every 5 years).
- Unit/filter status indication provided.
- Whisper quiet operation.
- Optional heater kit available.
- Optional manual boost switch available.
- Significantly improves indoor air quality.
- Can be used for Radon gas control.
- 5 year unconditional parts and labour warranty.
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.

KAIR TRACKMASTER - Kair™ Trakmaster KHRVF100 Heat Recovery Ventilators provide a continuous air change, replacing stale moisture-laden air with fresh, warmed air from outside. Kair™ Trakmaster KHRVF100 control condensation problems in small flats and bungalows and are an integral part of the Kair ‘Hybrid’ Heat Recovery Systems
Energy Efficient
Unlike conventional extractor fans which suck out and waste expensively produced heat, Kair™ Trakmaster KHRVF100 Heat Recovery Ventilators recover up to 65% of exhaust heat, even when operating on boost mode. The world is becoming increasingly aware of the enormous cost of energy production, and this, plus the use of fossil fuels to generate power, is a momentous environmental issue. Extractor fans potentially waste over a million kilowatts of energy every year. This is comparable to the total output of two large power stations. Replacing conventional extractor fans with heat recovery systems could save at least half of that energy loss.
Benefits
- Meets Building Regulations requirements
- Up to 65% Heat Recovery
- Easy to install (no external access required - 102mm core drill)
- Whisper quiet Continuous running trickle ventilation
- Humidity sensor (preset or adjustable)
- Low running costs Tamperproof screws (optional)
- Balanced or positive airflow
- Energy savings
- Security ventilation™ (no need to open windows)
- Health benefit - produces dramatic improvements of indoor air quality

USER GUIDE INSTALLATION GUIDE DATA SHEET

KAIR WHOLE HOUSE VENTILATOR - These ventilators have been designed to create a continuous input of air. This will effectively combat condensation dampness and mould growth. Kair loft units create a continuous drying out process in dwellings and will help provide protection for hygroscopic material such as books, leather goods, wooden furniture, clothing and other fabrics from mould.
Energy efficiency
Unlike conventional extractor fans, which suck out and waste expensively produced heat, the Kair™ Loft Input Ventilator utilises heat that exists in lofts through solar gain and simultaneously circulates existing heated air that has raised to ceiling height, heat which also helps increase temperature of the loft space air supply to the unit.
The continuous air movement throughout the property creates surface evaporation of moisture contained in the building fabric. This in turn, creates a drying out process, which means that there will be less hidden moisture to heat up increasing efficiency savings.
Kair™ Loft Input Ventilators consume less than a 60 Watt light bulb when in boost mode and less than a 40 Watt bulb when on background trickle.
Features
- Meets Building Regulations requirements Document F1 (Alternative methods)
- Easy to install (no external access required)
- Whisper quiet
- Continuous Running trickle or boost ventilation
- Humidity sensor (optional)
- Low running costs
- Positive input airflow
- Security ventilation™ (no need to open windows)
- Health benefit - produces dramatic improvements of indoor air quality
- Heat energy dividend (solar gain)
