Explosion-proof exhaust fans, or hazardous location fans, provide proper ventilation for spaces where flammable gases, vapors, or dusts may be present.  These fans are designed to be non-sparking, which minimizes the risk for sparks that could ignite potentially flammable materials.  For example, in an environment with flammable gases, if a non-explosion-proof exhaust fan were to tip over and hit against another metal object, a spark would very likely be emitted.  In the most at-risk locations, one spark is all it takes to cause an explosion.  Thus, the entire fan must be constructed with non-sparking materials, including aluminum or copper fan blades, and an explosion-proof motor.  An explosion-proof exhaust fan is a widely used piece of equipment in gas stations, chemical and metallurgy plants, and construction sites.

Each explosive-proof fan is marked with a specific code that provides vital safety information. When selecting an exhaust fan, refer to the fan’s safety code. Higher-risk work spaces require fans that meet safer standards, and using the wrong type of fan can be potentially hazardous.

These codes contain four pieces of information:  the classification standard (either American or Canadian), the protection concept code, the gas group, and the temperature code. This is a typical marking:

AEx t IIB T4

“AEx” means Explosion Protection, and it is the American standard classification code (the Canadian code is “Ex”). In addition, the “t” refers to the protection concept code, the “IIB” is the gas group, and “T4” indicates the temperature code.

A range of construction and industrial locations require the use of explosion-proof exhaust fans, and different types of ventilators to be used based on the facility’s explosion risk.  The fans are categorized into three class types that represent varying levels of risk:

  1. Class I

Class I locations are those in which flammable gases or vapors could be present in the air in quantities sufficient to produce explosive or ignitable mixtures.  These sites include paint spray booths, dry cleaning plants, and oil refineries.

  1. Class II

The facilities in this classification have combustible dust that may be present in varying hazardous concentrations.  Among these locations are grain elevators and food powder processing plants. The risk for explosion in these facilities is greater than Class I, and the materials have lower ignition points.

  1. Class III

Facilities in this class carry the highest risk and include locations like textile mills, cotton production plants, and woodworking facilities.  Class III hazardous locations contain easily ignitable fibers or flyings, but the concentration of these fibers or flyings are not suspended in the air in such quantities that would produce ignitable mixtures.

Advantages of Using HVAC Products in Your Home or Business

The most important benefit of using HVAC products in your business is pretty obvious … you create a pleasant working environment for your customers and staff!  Ideally, your HVAC equipment should keep you warm in winter, cool in the summer and breathing fresh air all year long.  Aside from the big items, like furnaces and packaged air conditioners, the scope of HVAC equipment available to you is very wide ranging.

Below are some examples of HVAC equipment and their advantages for your business:

Portable Air Conditioning Units:  If you live in a temperate location that doesn’t require installed air conditioning, you may still need to cool down occasionally.  A portable unit allows you to do so when required, wherever you need it.

Fans:  If air conditioning isn’t something that you are going to need on a regular basis, make sure your workplace has enough fans to offer a cool draft to make the heat less of a problem. There are fans of all shapes and sizes to fit your needs, including some industrial-sized blowers if required.

Air Curtains:  Air curtains deliver a continuous stream of downward air over a doorway.  The airstream prevents non-conditioned exterior air, as well as bugs, dust and fumes, from entering your space.



Air Purifiers:  You may not suffer from allergies, but some of your employees and customers might.  An air purifier’s filter ensures that they can breathe cleaner and purer air.  Several units are available that are suited for rooms of different sizes, and many models are portable.

Applications and uses for Ventilation Air Ducts

A ventilation air duct is a conduit or passage that is used to deliver or remove air, generally with the end goal of ensuring that the air quality is at acceptable levels. There are many different types of ventilation air ducts, and the applications and uses are different for each of them.



Heating, ventilation and air conditioning (HVAC) is the technology of making environments safer and more comfortable. Ventilation air ducts can play a role in the application of most elements of HVAC. This makes them important parts of almost any structure, particularly in climates where heating or air conditioning are essential. They also have important roles to play when it comes to industrial and scientific settings.

Knowing which duct is right for the job you have is crucial, particularly if the ventilation is required for safety purposes, so you need a good understanding of your requirements to help you know which air duct will help you achieve that.


Below are some of the types of ventilation air ducts available and the most common applications and uses for them:


HVAC Industrial Ventilation Ducts – As the name suggests, these are used in industrial settings like plant works, engineering spaces, chemical labs and engine rooms to make sure that the air inside doesn’t become unsafe to breathe by the processes and chemicals involved. There are also heat resistant ducts available that are designed to be used for drying paint or solidifying cement, among other uses.

Tips to help your Business Stay Cool during the Warmer Months

Creating a pleasant working environment for staff has become ever more important in the last few decades as we’ve learned more about what influences productivity along with an increase in job mobility seeing workers more likely to leave their employers if they aren’t happy with conditions. This particularly applies when the weather is hot during the summer months, as oppressive heat can drain energy levels and cause a great deal of discomfort. However as an employer, there’s plenty you can do to help.

Sky at Sunset

Nobody likes being inside at work on a sunny day, but if the temperature is so high that even office workers are struggling to get their jobs done, that isn’t good for anybody, and this is even more critical in workplaces where employees need to be up and about all day. So here are some tips for helping your business stay cool during the warmer months:

Summer cooling 1

Invest in Air Conditioning

If your workplace is in a town or city where the climate is generally very hot during the summer months, you should already have air conditioning, but even in more temperate locations it can be a necessity to have a system in place for when the thermometer soars. In these situations, rather than paying for a full installation, it might be more efficient and convenient (and cost-effective) to buy a portable air conditioning unit which can be used when required.

Buy an Air Curtain

If you work somewhere that requires a door to be open to allow in customers or loading vehicles, it can be hard to regulate the indoor temperature without being affected by the outside atmosphere. This applies equally whether it’s hot or cold, so an air curtain is needed to offer a barrier between the two temperatures that will prevent the hot air (in this instance) from replacing the air conditioned air.

Fans – Lots of Fans

One of the cheapest options for your business might be the simplest one – buy lots of fans. If air conditioning isn’t something that you are going to need on a regular basis, simply making sure your workplace has enough fans to offer a cool draft to make the heat less of a problem for all of your staff could be the way forward. There are fans of all shapes and sizes to fit your needs, including some industrial-sized blowers if required.


Stay Hydrated

And finally, the cheapest tip of them all. When the weather is hot, your staff will get dehydrated quickly, especially those having to be on their feet all day. Using the methods above to reduce the temperature will help, but even office workers need to stay hydrated during the summer, so why not supply them with not only a drinking fountain or cooler, but water bottles as well that they can be refilled whenever necessary.

Keep Your Home or Business Cool with HVAC Products

Summer is here and so are those unbearably hot weather days. On hotter days, you’ll need to have a plan in place for cooling your home or business. This is especially important in warmer climates where the heat is more persistent.

Sky at Sunset

Besides investing in an HVAC system, there are several other methods you can use to keep the heat out and the cooler temperatures flowing.

Follow these 9 steps to feel more comfortable.

1.) Start by keeping sun light out using blackout curtains, shades or blinds.

2.) Install a ceiling fan if you don’t have one. Ceiling fans will lower the temperature of any room and will make a great addition to your air conditioning system.

3.) If you have a ceiling fan, ensure it works properly. In the summer months it should rotate counterclockwise as opposed to clockwise in the winter months.

4.) Keep doors closed to prevent warmer air from flowing in. 

5.) Close the doors of rooms or offices that you don’t use to keep the cooler air in more frequented areas.

6.) Run appliances such as washers and dryers at night.

7.) When cooking, be sure to turn on the exhaust fan to quickly get rid of unwanted heat.

8.) Turn off lights when not in use.

9.) Use portable ventilators or misting fans inside industrial or manufacturing environments.

If you are willing to make the investment, there are more permanent changes or improvements that you can make to your home or office to prevent over heating and allow for greater air flow. This includes:

  • Added insulation.
  • Minimize heat from the sun by adding trees to your landscaping or installing awnings around large windows.
  • Install a dehumidifier to rid your home or office of extra moisture.
  • Install a cool or reflective roof.
