What is a Recirculating Vent?
A recirculating vent is an integral component of an over-the-range or built-in microwave that aids in ventilation. Unlike traditional microwave ventilation systems that vent air outside, a recirculating vent filters pollutants and recirculates the cleaned air back into the kitchen. This is especially useful in situations where external ventilation is not feasible due to structural constraints.
How Does a Recirculating Vent Work?
To understand how a recirculating vent operates, it’s essential to grasp its components and processes.
Key Components
A typical recirculating vent system includes:
- Grease Filters: These filters capture grease particles from cooking, preventing them from entering the air.
- Charcoal Filters: These filters absorb odors and other pollutants, ensuring that the air released back into the kitchen is clean and fresh.
- Fan: The fan circulates air through the filters, enabling the effective removal of contaminants.
The Filtering Process
The operation of a recirculating vent can be broken down into a few key steps:
- Air Intake: When the microwave is in use, it draws in air from the cooking surface below.
- Filtration: The air passes through the grease filter first to capture grease particles. It then goes through the charcoal filter, which removes odors.
- Air Recirculation: After filtration, the clean air is expelled back into the kitchen, providing the space with a fresher atmosphere.
