Core offering

Vent Systems Ltd manufactures and sells over-frame window trickle ventilators and extraction fans for kitchens and bathrooms under the VENTOVER brand. The core offering consists of combined extract fan and trickle ventilator units that fit within the window frame aperture without requiring wall penetration, suitable for UPVC, timber, and aluminium windows. The product range includes the B15 single-speed bathroom fan (15l/s), the K60 two-speed kitchen fan (60l/s high / 30l/s low), and the original VENTOVER trickle ventilator, all manufactured in Scotland and sold direct from factory or through authorised distributors.

Product overview

Vent Systems Ltd manufactures a focused product portfolio of window-mounted ventilation solutions under the VENTOVER brand. The core offering consists of combined extract fan and trickle ventilator units designed for installation within window frames, specifically the B15 single-speed bathroom fan (15l/s) and K60 two-speed kitchen fan (60l/s high, 30l/s low). Both products share the same over-frame window mounting principle. Optional add-on modules include humidistat sensors (integral or remote), remote PSU for SELV bathroom installations, PIR motion detection triggers, and variable speed controls. The company, established in Scotland since 1989, formerly sold these products under the Vent-Trex brand until the 2015 rebranding to VENTOVER.
