The Project Exhaust Fan with Run-On Timer is a practical, wall-mounted solution for compact bathrooms, laundries, and other humid spaces with no ceiling cavity. Designed for direct installation onto an external wall, it’s ideal where ceiling-mounted exhaust fans can’t be used or as a straightforward upgrade for an old, tired unit. Its flat fascia and matte white finish create a clean, unobtrusive look that suits any interior. A built-in adjustable run-on timer (1 to 30 minutes) ensures ventilation continues after the switch is off—helping manage lingering moisture and reduce the risk of mould. Available in two sizes with 100mm or 150mm cut-outs, it’s a simple, everyday choice for essential air extraction in tight spaces.
