1985 OK-334F Electronically Controlled Kerosene Fan Heater with Odor Absorption

In 1984, Sharp introduced the industry's first electronically kerosene heater with a built-in device for reducing the smell of kerosene at shut-down.
The next year (1985), Sharp incorporated this device into a popular kerosene fan heater.
The photograph shows the OK-334F with the odor-reducing function.
