The two main issues that ventilation manufacturers have been addressing in recent years when it comes to bathroom fans are energy efficiency and acoustic sound levels. When putting together our new installer friendly ventilation kit, not only did we take into account both these issues, we also considered other key ones often overlooked.
We addressed what fan would be best and what features it needed to make installation as quick and versatile as possible while giving the best ventilation rates. We also considered the importance and type of the outside grille and how weather and atmospheric conditions could affect the performance of the kit.
The new Monsoon ZONE 1 Energysaver™ Fan Kit consists of three parts: the Monsoon Zone 1 Silence Fan, a non-cut semi rigid wall sleeve and the independently tested Energysaver™ Grille. This kit provides the installer with a high performance, low noise, low energy, low carbon, IP45 fan suitable for mounting within Zone 1 and a unique wall installation kit which provides 20% less resistance than standard grilles or cowls and providing greater fan efficiency.
The fan, Monsoon ZONE 1 Silence IP45 is a perfect combination of silent operation and high efficiency with an aerodynamic mixed-flow impeller. With the benefit of being IP45, this means the fan can be mounted in ZONE 1 without a costly, bulky 12v transformer which is time consuming to install, saving the contractor time and money on site as well as giving greater flexibility when siting the fan.
Energy saving and quiet too, at full speed the energy efficient ball bearing motor uses a maximum consumption of just 7.5 watts and it’s casing incorporates anti-vibration mounts with maximum fan noise level of only 25 dB(A). So does this mean we are compromising on fan performance duty? No, the ZONE 1 fan has an impressive airflow performance of 97m³/hr (27 l/sec) which means it has Specific Fan Power of only 0.27 W/L/S.
Other fan features; the mixed flow impeller means it can be used with longer lengths of ducting if needed, the ball bearing motor means it is just at home mounted on the ceiling without additional noise factor and is available in five model options. The most popular is the timer model which allows the unit to be simply and easily adjusted between 2-30 minutes overrun. The other four models are a standard, pull cord, PIR triggered and a humidistat controlled, which also incorporates a timer module. A silent back draught shutter is factory fitted standard for all models, all fans also have a standard thermal overload protection on the motor and you can expect a typical service life of 40,000 hours.
One thing that is not given careful consideration is what to put on the outside wall and how this will affect the fan’s performance. Also weather and atmospheric conditions need to be considered as they too will also have an impact on the extract rate. Just a 5m/s breeze can severely affect a 100mm axial fan to the extent in windier conditions that blades can even stop turning.
So in the kit we have included an innovative new cowl designed to counteract the adverse effects of external wind on the performance of mechanical extract ventilation systems the Monsoon Energysaver™ Grille the patented product is up to 20% less resistant to airflow and has the capability to make any extractor fan up to 20% more energy efficient. The grille also alleviates ‘blow back’ thus further increasing extractor fan efficiency and reducing energy consumption - all of which contribute to a reduction in the carbon footprint.
The Monsoon Energysaver™ Grille is especially suited to installations in windy locations. Produced as a one piece moulding in tough, weather resistant PVCu, the cowl is supplied with a snap-on mounting plate. It is easy to install and requires no maintenance and with no moving parts makes the grille completely silent.
The grille is the only patented Part F Compliant, independently tested energy efficient ventilation grille on the market and coupled with the Monsoon ZONE 1 Silence Fan makes it the perfect combination for the installer, saving time and money as well as greater versatility and performance, making the kit one of the most energy efficient ventilation kits available today.
