The Most Powerful Negative Air Machine in its Size Class! 

The OmniAire 2500 Prime is a construction-grade negative air machine with the potential for optimal airflow performance. The machine comes standard, with a 6” Deep HEPA filter, 99.97% efficient at 0.3 microns, but it reaches the full CFM potential when operated with the optional 12” deep HEPA filter. 

The 2-speed OA2500 Prime can be used to create positive or negative air pressure with CFM ratings of 1000 and 1600 respectively. Perfect for use in containment areas for mold, asbestos, and lead abatement projects, silica containment on construction sites, restoration projects after water/fire damage, health care facilities undergoing construction, and many other applications.

The OA2500 Prime has a lightweight yet durable aircraft-grade aluminum housing that ensures mobility and easy cleaning while delivering long-lasting performance. With meticulous silicone sealing of critical seams, this machine protects against contaminated air bypassing the HEPA filter.

    OmniAire 2500 Prime - 1000 and 1600 TrueCFM™

    Central to the OA2500 Prime versatility is its 6” deep True HEPA filter, boasting an exceptional efficiency rate of 99.97% at 0.3 microns.

    Beyond offering the most CFM in its class, these machines are very versatile. They create controlled air pressure environments, whether you need positive or negative containment, and serve as an air scrubber in recirculation mode. This makes them indispensable for various critical applications, such as mold, asbestos, and lead abatement projects, silica control at construction sites, mold containment during water or fire damage remediation, and safeguarding healthcare workers and patients in medical facilities.

    Thanks to alternative pre-filters like poly pads, framed pleated filters, activated carbon filters, and specialized Bag Filters designed to handle substantial volumes of construction dust, adapting the OA2500 for various applications is a straightforward process.

    This model holds UL/CSA Safety Certification, and features a thermal protection overload monitor, guaranteeing 24/7/365 safe operation.

    OmniAire machines with a TrueCFM™ air flow specification 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 contact us at
