Each heater element is covered with a removable “Iso-shield” which provides more even heating throughout the oven’s interior without the need for separate trays.

The 4″ ducted exhaust port allows for easy adaption to standard dryer venting systems to safely vent heat and fumes outside with the high capacity 56CFM fan. Heat loss and drafting is prevented with a stainless steel flap valve.
