No matter what type of trailer, proper ventilation is necessary for health, safety, and comfort. This can be effectively achieved by combining natural and mechanical ventilation methods.
Fresh air can flow through your trailer by natural ventilation methods such as windows, fixed vents, and skylights with built-in ventilation. Positioning windows on opposite sides is always a good idea for creating cross ventilation. Vents should be placed at both high and low points to take advantage of natural convection, where hot air rises and cooler air settles. It’s important always to be sure that vents are not blocked by an obstruction, which will mitigate effectiveness.
Installing roof and side vents is especially crucial for utility trailers transporting perishable goods.
In climates where natural ventilation is not enough, mechanical ventilation can be achieved via roof-mounted exhaust fans, air conditioning units, and portable fans. Individually or in combination, these methods can effectively remove hot air from the trailer and improve air circulation. When using a mechanical system such as air conditioning, schedule regular maintenance to clean vents and fans and replace air filters when needed.
