Improved SFP Ratings

Vectaire has improved the SFP rating on the WHHR100/90DC-B Plus and the MBOX125/2DC-B. They have been retested by BRE and the results published.

The WHHR100/90DC-B Plus is a whole house ventilation unit with heat recovery, for installation in homes and offices. Its DC motor gives high efficiency, low energy usage and recovers 92% of heat from extracted, polluted air. It is for loft, roof void, or cupboard installation.

The MBOX125/2DC-B is an efficient, low energy solution to condensation and pollution, providing low level continuous ventilation. It is for loft or roof void installation and requires only one discharge grille. Also available with rectangular spigot - MBOX125/2DC204-B.

Both units are continuous running with choice of trickle and boost speeds with low noise levels and running costs. They are compliant with Parts L and F of the Building Regulations.
