2.0 INTRODUCTION
The Nuaire range of Opus 230V fans have been specifically designed
to ventilate areas such as the bathroom, toilet, stores, drying rooms,
cupboards etc.
The range consists of three duty ranges, 40l/s, 60l/s and 95l/s.
The 40 and 60 models are available as single and twin fan variants
(twin fans are duty sharing). The 95 model is dual fan only (both fans
run simultaneously).
The unit package is supplied to offer the installer 3 alternative
mounting options.
The unit discharges air through a 100mm diameter spigot which for a
surface mounted unit exits at the rear, and for recessed mounting can
be discharge either through the rear or top of the unit (Figures 1 - 3).
Air entering the unit passes through the front grille and can be filtered
via an optional foam filter.
The motor(s) are 24V brushless DC. Bearings are sealed, self-lubricating
ball type with integral locked rotor protection. The fan / motor
assembly can be fitted in one of two positions (Figures 6 & 9) and is
held in place by the yellow fastener located at the rear of the unit.
