• Nuaire's award-winning range of MRXBOX95 heat recovery systems are designed to provide optimised, balanced supply and extract mechanical ventilation with heat recovery. The MRXBOX95-WH1 is our most powerful unit, capable of ventilating medium to large properties with up to seven wet rooms.

    This high duty system has ultra-low Specific Fan Power (SFP) and will recover up to 95% of heat which would normally be wasted, both of which will help you meet the Code for Sustainable Homes level 3 or above and achieve a high score on SAP Appendix Q.
