Kitchen extraction fans without exhaust, also known as recirculating fans, offer a practical solution for kitchens where venting to the outside isn’t feasible. These fans filter the air rather than expelling it, making them ideal for apartments or homes with limited exterior access. This guide explores the benefits, drawbacks, installation, and maintenance of these versatile appliances.
Understanding Recirculating Kitchen Extraction Fans
Recirculating fans work by drawing in air, passing it through a filter to remove grease, odors, and other airborne particles, and then circulating the cleaned air back into the room. Unlike traditional exhaust extraction fan systems that require ducting to the outside, these fans are much simpler to install. They are an excellent choice for kitchens lacking exterior walls or where ducting installation is problematic.
Benefits of a Kitchen Extraction Fan No Exhaust System
Opting for a kitchen extraction fan with no exhaust provides several advantages:
- Easy Installation: No need for complex ductwork makes installation quick and straightforward, often achievable with basic DIY skills.
- Cost-Effective: Lower installation costs compared to vented systems due to the absence of ducting materials and labor.
- Energy Efficiency: Recirculating fans generally consume less energy as they don’t expel heated or cooled air from the kitchen.
- Suitable for Restricted Spaces: Ideal for apartments or kitchens where exterior venting is impossible.
Drawbacks to Consider
While convenient, recirculating systems do have some limitations:
- Filter Replacement: Regular filter changes are essential for maintaining efficiency. Filters typically need replacing every 3-6 months, adding to ongoing costs.
- Less Effective Odor Removal: While they reduce odors, they might not eliminate them as effectively as extractor fan hood systems that vent to the outside.
- Moisture Removal: Recirculating fans don’t remove moisture from the kitchen, potentially leading to condensation issues in humid environments.
Installation of a Recirculating Kitchen Fan
Installing a recirculating fan is relatively simple. Typically, it involves mounting the fan unit below a kitchen cabinet or on the wall above the cooktop, connecting it to the power supply, and ensuring the filter is correctly in place. However, consulting the manufacturer’s instructions is always recommended.
“Always ensure the power is disconnected before beginning any electrical work,” advises John Davies, a certified electrician with over 20 years of experience.
Maintaining Your Kitchen Extraction Fan No Exhaust
Regular maintenance is crucial for optimal performance. This primarily involves replacing the filters as recommended by the manufacturer. Some filters are washable and reusable, offering a more sustainable and cost-effective option.
“Regular cleaning of the fan housing itself will also help prevent grease buildup and maintain airflow,” adds Davies.
Conclusion
A kitchen extraction fan with no exhaust provides a practical ventilation solution for many kitchens. While not as powerful as vented systems, their ease of installation, affordability, and suitability for restricted spaces make them a popular choice. By understanding the benefits and drawbacks, and committing to regular maintenance, you can enjoy a cleaner and more comfortable cooking environment.
