Confined space blowers provide workers with fresh, breathable air while working in confined spaces or extract fumes, because air may not move freely in and out of confined spaces due to the design; the atmosphere inside can be very different from the atmosphere outside. Ventilation blowers must be properly sized to provide the right amount of fresh air or remove contaminants.
