Heat-recovery ventilation unit fits 100 mm-diameter hole
Vent-Axia’s Lo-Carbon Tempra heat-recovery ventilation unit can achieve up to 74% heat recovery and be retrofitted through a 100 mm-diameter hole in the wall. These units are discreet and quiet in operation and be set to run continuously at 6 or 9 l/s, boosting up to 13 l/s if required. For intermittent extract application, the airflow can be set to 15 l/s. A manual Summer bypass operates the unit on extract-only when it is warm outside to prevent overheating.
There are four models — a standard version, option controlled by a light switch, T version with over-run timer and H version with built-in humidistat.
