What is so special about our range hoods
This blog explains why our range hoods are superior to most other kitchen hoods in the market:
1. We use the highest grade of stainless steel and other metals such as copper for all of our range hoods
1. Stainless steel comes in various grades - we use 304 which will not develop rust streaks over time - these are thin lines of rust that push through because there is a high percentage of iron in the stainless steel
2. A simple test to check if your range hood is premium stainless or has a high iron content is to place a magnet on the hood - if it sticks then it is not 304
2. Our copper range hoods for instance are made from solid copper - we do not use a thin sheet of copper applied over steel
3. Most of our range hoods are supplied with 304 series dishwasher safe baffle filters - these unlike typical aluminum mesh filters are near indestructible and will never require replacing
1. Baffle filters also do a far better job of capturing contaminants at higher speed
2. These filters are typically quieter than mesh filters and will not choke under excessive smoke and steam conditions.
4. We offer the option of mesh filters and even these are made from 304 stainless steel casing that covers the entire surface of the filter.
5. During the construction of the hood we use whats called double wall construction - this ensures that the hood body is rigid and will not flex or vibrate which contributes to a noisy hood fan
6. The lighting systems on the range hoods are 120v halogen floods as distinct from low voltage lighting - the use of low voltage lighting introduces a transformer into the electrics which typical stay connected 24/7 resulting in a high failure rate of these transformers
7. The blower and lighting controls are solid state rheostat which enables the user to have very precise control of the setting on both the blower and lights. This means that the lights and blower can be "dialed" up to the exact intensity required - there is no plastic or switching parts that can fail or become encrusted with grease. The knobs on these controls are also solid metal.
8. Every hood is made by hand - we do not use a robotic production line as we focus our attention on the finished product and the desired look of the hood
9. The blowers are top of the line and considered one of the quietest and most reliable in the world
10. We do not compromise quality - our focus is on making the best range hood from top of the line materials and we therefore do not attempt to compete on price
Hopefully the above provides a brief insight into why our hoods rank as one of the best manufactured range hoods in the world.

Make-Up Air Systems
Why do we need Make-Up Systems
1. Our homes have become extremely air tight with the result that fresh air replacement from outside via air seepage, can no longer be relied upon to bring in clean air. The result is that the air quality on our homes becomes very unhealthy. So in order to improve this air quality we need to find a way to bring in fresh clean air and evacuate or clean the stale air. This is achieved with make up air systems. You can liken the situation to living inside of a sealed plastic bag - without make up air - particularly in winter the air quality becomes very poor and unhealthy.
2. Now if you add a kitchen range hood that evacuates large amounts of air, the situation actually becomes far worse - we are exhausting the air from our sealed plastic bag example above and without any make up air bringing air back into the "plastic bag", the environment actually becomes depressurized - the pressure inside the bag rapidly becomes less than the pressure outside - the results can be catastrophic as our heating equipment such as fireplaces, hot water tanks and furnaces rely on balanced air pressure to exhaust the poisonous gases to the outside. When a home becomes depressurized these gases actually get drawn back into the environment with the lowest pressure - the "plastic bag" - our home.
So what do make-up air systems do. Very simply they are linked via pressure switches or electronic switching to suck air back into the home as it is exhausted and to constantly bring in a supply of fresh air. By way of example, when we use our range hood that is say exhausting 600cfm (cfm = cubic feet per minute - visualize a block of air that is 12"x12"x12" - that's 1cfm), now with a 600cfm range hood that is 600 of these blocks of air every minute leaving our "plastic bag" type home - under this situation the average home would attain a negative air pressure situation very very quickly and the dangerous gases from our appliances would invade the home and its occupants.
The make-up air system would be activated before this negative air situation has had chance to develop and would pull air back into the home to replace the exhausted air - make-up air system must of course also heat this air before bringing it back into the home in winter and cool it in summer.
So that very simply is how make-up air systems work and why we need them.
Below please find copy from the Uniongas website on make-up air:
http://www.uniongas.com/business/gastechnology/productsservices/iaq/iaqMakeupAir.asp
In most cases, the need for ventilation air is achieved by the addition of a make-up air unit(s). These units are essential to a building's mechanical operation and to the health and comfort of its occupants. By providing a controlled quantity of clean, conditioned ventilation air to common areas of the building, they:
•Reduce drafts, dust and dirt entering the building;
•Replace air exhausted by equipment such as kitchen or bathroom fans or process or industrial exhaust fans;
•Reduce odours.
A make-up air unit consists of a fan and a heat-exchanger component as well as filters and dampers. Gas-fired units are available in many sizes to meet building ventilation needs and are supplemented by a variety of control components (both temperature and air quality) and operating strategies. Control systems are important as they can be designed to handle 100% outdoor air or to mix outdoor air with re-circulated indoor air. Mixed air systems can be electronically controlled. Heating can be provided at fixed or variable heating rates and control strategies for these systems can also vary from simple manual systems to computerized options.
Depending on the application, make-up air units can be installed either on rooftops or indoors. High-rise buildings generally install their units on rooftops, where they are mounted on either a curb or metal roof frame, then connected with the building's electrical and duct work system. In walk-up apartments, units are often installed in utility or attic rooms and conventionally ducted to feed air to the corridors and common areas.
A variety of features are available that will enhance the performance of make-up air units, including:
•Heat reclaim coils or heat wheels, to recover waste heat;
•High efficiency filtration to maintain air quality and automated controls governing both temperature and air quality to minimize energy consumption - including capacity control utilizing two-stage or modulating gas valves that will match the unit's output with your building's needs.
Electric make-up air heaters can also be converted to natural gas by installing a heating coil in the duct, which is heated by hot water that is supplied by a gas-fired boiler.

How much cfm do you need for your cooking equipment
What type of ventilation is required for your coking equipment? In order to determine the proper amount of air flow required for your cooking equipment, you must first know how many BTU’s (British thermal units) your gas range emits. Then, with a simple calculation you can determine the amount of CFM (cubic feet per minute) required to properly exhaust your cooktop. For example if your cooktop emits 90,000 BTU’s you would divide 90,000 BTU’s ÷ 100 = 900 CFM. This means that 900 CFM or more would efficiently exhaust your range. For electric and induction cooktops choose a blower with a minimum of 200 CFM per 12 inches of cooktop width. Remember, it’s always a good idea to round up versus down.

Baffle or Mesh Filters
The question is often asked what is the difference between baffle and mesh filters. Apart from the appearance baffle filters are more efficient than mesh filters because they permit the easier flow of air through the filter. When air passes through a baffle filter it must make 2 x180 degree turns and in so doing must speed up to make that turn - when the air speeds up it deposits the grease and moisture onto the bend in the filters. Baffle filters are also better at eliminating the posibility of a fire running up into the ductwork.
Baffle filter
Mesh filters on the other hand consist of anywhere from 3 to 6 layers of fine mesh laid one upon the other - so the air is forced to pass through tiny holes creating more noise and typically less efficient than baffle filters.
A Modern Aire Mesh Filter
Baffle and mesh filters are normally dishwasher safe and it is very important to wash them both on a regular basis to avoid not only a fire in the filter but also to ensure grease is not sucked through to the blower and inside of the hood.
Not all mesh filters are created equally - Modern Aire uses high quality stainless steel that has holes punched on the outside - this protects the finer mesh from damage. Most of the mesh filters on the market do not have this protective layer of stainlees steel and the finer aluminium mesh gets easily damaged when placing in the dishwasher.
