What do you need to consider when buying an extractor hood and which exhaust air systems are used?
Exhaust air extractor: Exhaust systems with exhaust air operation vacuuming the cooking vapours are completely removed and directed outside. Therefore, a wall break is necessary for operation.
For this reason, Exhaust hoods can also be attached to or next to an external wall. The exhaust air systems therefore do not require carbon filters and you regularly save money. There may be some energy loss due to the wall breach. If you want to minimize energy loss, you can use a flap that closes as soon as the extractor is switched off.
Exhaust system with Recirculation systemAt the SPC you have the choice!
Hoods with recirculating air systems eliminate vapours during cooking by directing the air through a carbon filter for cleaning. In order to permanently prevent mold formation due to moisture during cooking, a controllable ventilation system is important.
Recirculating hoods are more suitable in mine houses as it does not generate any heat loss.
