Negative Air Machines

Negative Air Machines and portable air scrubbers are indispensable tools in abatement, restoration, and healthcare projects dealing with hazardous substances like asbestos, mold, lead, and other hazardous particulates. Whether used for containment in abatement projects or as continuous air scrubbers in recirculation mode these versatile machines play an important role in ensuring the safety and cleanliness of high-stakes environments.

Recognizing the pivotal role of CFM (Cubic Feet per Minute) calculations when operating Negative Air Machines is essential. Accurate CFM values are key to optimizing ACH (Air Exchange Rates per Hour) when maintaining a containment space. The importance of precise machine ratings cannot be overstated, as they directly impact the calculation of ACH. To that end, Omni CleanAir has established a TrueCFM™ ratings for all our machines, to ensure accurate project calculations.

How it Works

Understanding CFM

CFM stands for Cubic Feet per Minute of airflow and is a critical calculation for any negative air machine, or air scrubber. It represents the volume of air moved through the Negative Air Machine. All Omni CleanAir machines are designed with sealed HEPA filters meaning 100% of the air flowing through the machine passes through the HEPA filter.

It’s important to note that not all CFM specifications are equal. Some stated rates may be higher than the actual volume of air per minute run through the filter. Our TrueCFM™ rating ensures the machine will deliver the specified CFM and can be independently verified.

OmniAire machines with a TrueCFM™ air flow specifications have undergone a rigorous and precise method for CFM measurements that is transparent and repeatable by any qualified third party. TrueCFM™ specifications are established using a new (unloaded), factory-certified HEPA filter, installed in the applicable OmniAire machine. For details regarding test setup and procedures, you may contact us at info@omnicleanair.com.

Understanding CFM

PREFILTER

Prefilter catches very large particles, extends the life of the HEPA.

Sealed Hepa

HEPA sealed at exit, ensuring only treated air is pulled through.

Blower

Motor, Blower, HEPA size/speed/etc., optimized to achieve maximum air flow.

Air Scrubber Machines

All negative air machines can scrub the air. However, Air Scrubbers, also known as air filtration devices, may not have the features necessary to operate as negative air machines. Air Scrubbers purify the air by removing particles, gases, and contaminants and reintroducing the filtered air back into the room.

Air Scrubber Machines

Negative Air Machines

A negative air machine creates negative pressure in a sealed containment space by pulling air through a HEPA filter and exhausting the filtered air to the outside. Creating negative pressure prevents the spread of dangerous contaminants and particulates from the space. These machines use a combination of filters, including high-efficiency particulate air (HEPA) filters, activated carbon filters, and MERV-rated pre-filters to trap and eliminate airborne pollutants.

Negative Air Machines

Air Changes Per Hour

Regardless of the mode of operation, it is essential to ensure the machine delivers the required air changes per hour (ACH). The higher the ACH, the safer the environment becomes for people.

Negative air applications in critical environments require a minimum ACH to achieve sufficient negative pressure (measured in inches of water column) to comply with federal and state OSHA (Occupational Safety and Health Administration) codes.

Applications

Abatement & Restoration Projects

Negative air machines and portable air scrubbers play a pivotal role in containing and controlling airborne contaminants during abatement and restoration projects. They help in minimizing the dispersion of toxic substances like asbestos fibers, mold spores, and lead particles, ensuring the safety of workers and preventing cross-contamination.

Healthcare Settings

In hospitals, these machines are deployed for patient isolation and infection control. Patient isolation involves creating negative air pressure environments, which confine airborne pathogens within isolation units, reducing the risk of contagion within healthcare facilities. Infection control standards outline measures healthcare facilities should take during construction and remodeling projects to mitigate the dangers posed by dust, mold and fungi, and other pathogens.

Pandemic Response

Negative air machines and portable air scrubbers have proven their worth in pandemic response strategies. They aid in setting up temporary medical facilities, quarantine zones, and testing centers by maintaining controlled environments that limit the spread of infectious agents.

Natural Disaster Response

During natural disasters like hurricanes, floods, and wildfires, these machines contribute significantly to recovery efforts. They help mitigate indoor air pollution caused by external contaminants, ensuring that indoor environments remain as safe and breathable as possible. In the case of water damage, negative air machines limit the spread of toxic molds during remediation and restoration projects.
