Ventless Hoods FAQs

What is a Ventless hood?

A Ventless Hood does NOT need to be vented outdoors. Ventless systems extract grease and moisture from air captured above cooking appliances without the necessity of a typical building hood system. It recirculates the heated air and releases clean air back into the interior space.

How does it remove the smoke and grease during the cooking process?

With a series of special filters. Most models have 4-stages of filtration.

Can filters be cleaned and re-used?

All Wells Ventless systems have removable grease baffle filters that can be cleaned. The other filters cannot be cleaned and are disposable.

How does an operator know when to change his filters?

There are series of indicator lights on the front of the hood that illuminate when filter maintenance or replacement is required.

Will a Wells hood remove odor?

No UL710B listed systems will remove 100 percent of odor produced. This includes standard type-one hoods that are vented outdoors. Air exchange is recommended to reduce the effects of odor. Dilution is the solution to odor removal. The more fresh-air into the space means fewer odors from cooking. We recommend you have an engineer or mechanical contractor review your plans and existing HVAC system.

Can all Wells hoods be direct vented?

All wells hoods can be direct connected or indirectly connected to vent ducting to go outside to remove odor and / or heat. Filtering the air and taking it outside can be done with traditional vent ducting which is far less costly than Type I “black iron” installations.

Do these hoods include a fire- suppression system?

Yes, most models of Wells Ventless hoods include an on-board ANSUL type system and are included in the price.

Does the hood come with the fire suppression system charged and ready to go?

While everything is provided, a licensed ANSUL agent is required to charge and tag the system for the local fire Marshall.

Is a Ventless more expensive to operate than a traditional Type-1 hood?

Traditional Type-1 hoods require cleaning and inspection by a third party at least twice per year, some municipalities require this four times per year. Wells hoods do not require this maintenance which off-sets the cost of operation. Typical average operating cost is just under $3,000.00 per year.

Can Gas appliances be used under recirculating air hoods?

Only electric appliances can be used under UL710B listed hoods

Can electric Char Broilers appliances be used under recirculating air hoods?

Generally not. Electric char-broilers are not permitted as cooking temperatures and grease emissions exceed acceptable levels.

Can any electric appliance (except char broilers) be used under a Ventless hood?

Yes most can. UL does have certain limitations of size, height, temperature and KW ratings. The approved list is very broad and wide. This includes fryers, griddles, ovens and more. Ask Wells to check your equipment schedule to verify everything fits and is UL compliant.

Does a Wells authorized service agent install recirculating hoods?

General contractors licensed in that City/State typically install the hoods. Authorized service agents are only required for warranty service.

What is the temperature of the air discharge from the hood?

The discharge temperature of air is determined by the appliances that are used and production rates. The hoods are not designed to remove heat not absorbed by food products while cooking. Related mechanical systems should be designed to compensate for this.

Where do the Wells Hoods ship from and how are they shipped?

All Wells hoods are crated and ship FOB Smithville, Tennessee, and are designed to fit through a 36 inch wide door. Special consideration should be made when shipping the WVU48, 72 and 96 models as they ship in oversized crates.

Can a Ventless Hood be moved when our lease expires?

Yes, unlike traditional hoods, these are considered equipment rather than part of the building.

Are there tax or cash-flow advantages when using a Ventless Hood?

Absolutely; since a Ventless hood is considered equipment rather than a capital improvement (like a traditional hood) it can usually be depreciated over a very short time frame.

Do Ventless hoods support green and sustainable initiatives?

Yes because the bi-products of combustion, smoke, grease and particulates are not discharged into our environment.

Are permits required?

This is the prerogative of local city, county and state regulatory agencies. Fire system, electrical and mechanical permits may be required in your area.

Are Wells Ventless hoods approved for use everywhere?

Wells has approvals in all 50 states and throughout the Canadian Providences. This includes all major cities in North America.
