Brookvent Aircycle 4.1 Heat Recovery Ventilation Unit| Wall Mount | Summer Bypass | Digital PCB Inverted Configuration, Grey

Incorporating the market-leading RecairTM counter-flow, air-to-air heat exchanger, the aircycle 4.1 succeeds in transferring up to 90% of the heat from the extracted air being taken from the wet rooms to that of the fresh air supply stream. This ensures high levels of indoor air quality can be maintained while greatly minimising heat loss. Down to 0.57w/l/s specific fan power - Streamlined, low-turbulence airflow path design coupled with state of the art EC fan technology ensures the aircycle 4.1 has the lowest power consumption (W) per volume of air (l/s) output in its class, minimising running costs and setting a new standard in HRV system efficiency. Integral humidistat - Continuously monitoring the humidity level (% RH) of the extract air from the property, the system’s integral humidistat automatically operates the boost (high) setting of each fan to reduce indoor humidity levels to the preferred, adjustable RH comfort level. Summer Bypass - A variable, tempering summer bypass mechanism operates by gradually increasing the amount of air directed around the heat recovery core as the temperature of the supply air from outside rises. This automatic feature helps to ensure total user comfort during warmer summer months by reducing the amount of heat being added to the fresh, filtered supply air. Auto-Boost Integration - The programmed boost (high) speed setting can be easily triggered via any 230v switched live signal (e.g. bathroom light, PIR motion sensor, boost switch, BMS) offering multiple means of intelligent, automatic control integration. This ensures pollutants are extracted immediately when created and at a much quicker rate. Automated Frost Protection - the supply fan to turn off for 5 minutes every hour when it senses temperatures below the 5 oC the set level allowing the warm extracted air from the home to pass through the core unaccompanied by the cold fresh in-take air. This action succeeds in regularly raising the overall temperature within the Heat Recovery System preventing the potential formation of ice particles which could cause damage Tool free easy access filters - The filters of this HRV unit will usually need to be changed every 6 - 12 months depending on occupancy/ use, and the type of environment the dwelling is located in (I.e. urban/ rural, and their associated levels of airborne pollutants). Requires a Digital Controller (Sold Separately) - This has a status indication.
