Shipping Containers that are stored in hot or humid environments may require ventilation to minimise excessive heat, foul odours, condensation and humidity. Whirly bird spinning vents or rotary vents can be positioned anywhere on the roofline of the shipping container. We also offer a variety of differing sized wall vents that when installed sit flush with the container walls. All are weatherproof in standard conditions. Vents are perfect when electricity or air conditioning are not available.
