Too much fresh air can mean expensive energy bills, which is why good ventilation in your home is needed to regulate the level of health and safety you need.</span></p> <p><span style="font-size: 16px;">Reduce temperatures – When there are a few people in a confined space, the environment can soon become hot and stuffy. A well-ventilated room will instantly be more comfortable - creating a more relaxed environment, while also making for a more productive workplace.</span></p> <p><span style="font-size: 16px;">Health benefits – Indoor air pollution coupled with bad ventilation can lead to a number of health problems including headaches, allergies, asthma, rashes, and sinusitis. However, this can be avoided with the installation of a crawlspace fan with a humidistat.</span></p> <p>The VentirPro 540 uses an 8.7" aerofoil fan to produce 540CFM flow and cover spaces up to 5600 cubic feet to provide more efficient ventilation.
