Multi-Vent는 부엌이나 욕실같이 떨어져있는 곳의 환기를 동시에 조절할 수 있도록 설계되었으며, 상업용 시설에서도 마찬가지로 적용 가능하다.
새로 건축하는 건물은 물론, 리모델링하는 건물에도 손쉽게 설치할 수 있다. 토출되는 배기의 주변온도는 최고 +44^oC까지 이다.
To 배기와 흡기의 적정한 콘트롤을 위해 Multi-Vent fan의 속도를 선택할 수 있다. 상,중,하의 속도조절을 통해 부엌이나 욕실등에서 나오는 수증기, 연기, 안 좋은 냄새를 매우 효과적으로 배출시킬 수 있다.
설계에 있어서 설치의 용이성과 성능에 대한 신뢰성 및 간단한 검수가 특히 강조되고 있다.

Introducing the New LoWatt Multivent for improved energy savings. Multivent continuous mechanical extract ventilation range is designed for the simultaneous ventilation of separate areas in the home or as a multi-point extractor system for a wide range of commercial applications.

In the home the system is usually located in the loft or airing cupboard with ducts taken to the bathroom, kitchen and utility room to remove water vapour at source and from WC's to remove odours. Designed to provide 0.7 of an air change based on the volume of the building, the Multivent system provides adequate ventilation, even in a 'tight' dwelling. Pollutant concentrations can be controlled and humidity maintained. A two pole single gang switch can be used in the kitchen to boost the fan speed if required.

Choose a Multivent speed to suit the volume of the dwelling, this is multiplied by 0.7ACH. As a guide, in a three bedroom house

using layouts with 125mm ductwork, a resistance of between 125-175pa can be expected. 100mm ducting can be used but keep air velocities below 4m/s. Check the system resistance in order to select the appropriate model and speed.

Multivent is ideal for a range of commercial multipoint extract applications such as stalls in lavatories, fitting rooms, kiosk's and processes. The units can be installed at any angle and where the ambient air has a high humidity content condensate drains are provided.

The New Lowatt MVDC Multivent minimises running costs by incorporating the latest DC technology. DC efficiency means less wear and tear on the motor which guarantees longer life.

Multivent MV250 and MV350 are guaranteed for 2 years with an extended motor guarantee to 5 years offered on the MVDC LoWatt model.

Multi point exhaust fan. Two models MV250 and MV350. Three pre-settable speeds. Standard Thermal Overload Protection (S.T.O.P.). Very low sound levels. 100 or 125mm circular spigots for speedy installation. DEMKO and KEMA KEUR approved.

Supply and install a Multivent wholehouse ventilation system as manufactured by Vent-Axia Ltd, Fleming Way, Crawley, West Sussex, RH10 9YX, Telephone: 01293 526062. The system should be able to extract from multiple areas within a property not exceeding 450m³. The system should be mounted in a loft area or kitchen cupboard with one outlet to atmosphere. The unit should be BEAB approved.

The unit should have three speeds and be capable of running at low speed with boost facility to increase to any of the higher speeds.

The unit should meet building regulations under the alternative approach Digest 398 from the British Research Establishment (BRE).

The motor should be of the backward curved centrifugal type and have sealed for life ball bearings for no maintenance and any angle installation and be fitted with Standard Thermal Overload Protection (S.T.O.P.).
