Why You Should Want An EnviroVent 2

• Removes fumes, odors and vapors. Particularly useful when firing materials such as metallics, and high sulfur clays, which can emit strong odors
• Improves firing consistency. The vent also helps to prevent different color glazes from migrating. You can now fire greens and reds on the same shelf with excellent results.
• Fits popular kilns. The EnviroVent 2 fits Skutt 16, 12, 10, and 8-sided kilns as well as many other kiln brands.
• Fits popular kilns. The EnviroVent 2 has a spring-loaded collection cup that keeps a tight seal on the kiln as it expands and contracts without stressing the bottom slab.
• Ideal for automatic kilns. The EnviroVent 2 makes firing kilns such as the Skutt KM series much more convenient. There’s no lid propping. Just put plugs in all the peepholes and press start.
• Never Pro-Rated.
• Serviced by the most extensive, knowledgeable and talented distributor network in the industry.
• Backed by a company whose mission statement is “We help you make great things”. When your kiln is down, you can’t make great things.

Downdraft Vs Overhead

There is nothing inherently wrong with overhead venting. It does a great job of removing heat from the room and it will get rid of the majority of fumes. The problem is that many people make false assumptions (sometimes induced through advertising) about the true function and capabilities of overhead vents marketed for kilns. 
Not UL Listed
The Skutt EnviroVent2 is the only UL listed venting system available on the market today. Other vents may use UL parts, but they are not UL listed because they have not been tested with a kiln. Your insurance company will like this!

Not Engineered to Remove Heat
It is true that any overhead vent will remove heat from the room, how much still needs to be determined by a qualified HVAC technician. You may find that it is cheaper to remove the heat through existing ventilation.Either way, you still need to pay someone to make these calculations based on the size of the room, the insulation and the BTUs that will be produced by the kiln.

Not 100% of the Fumes
The Envirovent creates a negative pressure system to remove the fumes before they enter into the room. An overhead vent needs to wait until they escape from the kiln to collect them.

Does Not Improve Chamber Atmosphere
Overhead vents do nothing to improve the atmosphere in the kiln which is one of the most beneficial outcomes of kiln venting. And as much as the overhead guys would like to make you believe that downdraft vents are “expensive to fire” because they bring in cool air and exhaust warm air, it is not true. The energy use is affected by less than 1%. in fact it is more efficient to vent with a downdraft because you completley seal the kiln unlike an overhead vent where it is necessary to leave the top peep out and prop the lid to 1000 F.
