Portable equipment designed to create negative air pressure within a contained space is frequently employed in construction, remediation, and healthcare settings. This equipment typically consists of a fan, a filtration system (often HEPA filters), and ducting. For instance, isolating a room during renovation prevents the spread of dust and debris to other areas.
Maintaining air quality and controlling airborne contaminants are crucial for protecting occupants and workers from potential health hazards. Historically, achieving such control required complex and costly fixed systems. Renting portable units provides a flexible and cost-effective solution for short-term projects or emergencies, offering a significant advantage over permanent installations. Furthermore, this approach allows for rapid deployment and adaptation to varying project needs.
