Welcome to our website! As we have the ability to list over one million items on our website (our selection changes all of the time), it is not feasible for a company our size to record and playback the descriptions on every item on our website. However, if you have a disability we are here to help you. Please call our disability services phone line at 610-265-9493 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability. Finally, your personal shopper will explain our Privacy Policy and Terms of Service, and help you place an order if you so desire.

The Faber MUDAMPER8 8-in. make-up air damper brings fresh air back into the home and improves hood performance. With higher cfm hoods more air is exhausted in tighter homes with less air coming back in. To "make up" for lost air, the universal make up air kit brings fresh outside air into the home through a separate fresh air duct. The automatic damper opens inside the duct to bring in air when the hood is operating above 400 cfm and closes tightly when the hood is off. The kit includes 8-In. switch assembly, 8-In. automatic return air damper, and 24-Volt plug in transformer. The air switch assembly attaches on top of the hood in the duct work and via low voltage wire "talks" to the make-up air damper. The air switch at the hood duct exit, activated by air flow, opens the damper outside to let in fresh air. The air switch then lowers when hood is off & tightly closes the outside damper. It opens when the hood is on, and closes when the hood is off.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
