OmniAire OA2500 PLUS-A — 2500 CFM HEPA Negative Air Machine with Audible Alarm

The OmniAire OA2500 PLUS-A is the upgraded version of the OA2500 PLUS, featuring all the same professional-grade performance with the added safety of an audible alarm that signals when the HEPA filter requires replacement. Designed for demanding jobsite environments, this 2500 CFM negative air machine delivers reliable air filtration and pressurization control for mold remediation, construction, demolition, renovation, and ICRA (Infection Control Risk Assessment) healthcare projects.

Key Features

• 2500 CFM Airflow Capacity — Powerful enough to handle large containment areas and high-dust environments
• True HEPA Filtration — 99.97% efficiency at 0.3 microns, capturing mold spores, asbestos fibers, lead dust, and fine particulates
• Audible Filter Change Alarm — Alerts operators when the HEPA filter is loaded and requires replacement, preventing bypass air leakage
• Wood Frame Construction — Durable, lightweight wood frame built for repeated jobsite use
• Negative Air Pressure Control — Maintains containment integrity in remediation and abatement zones
• Multiple Application Support — Suitable for mold remediation, asbestos abatement, lead paint projects, construction, and ICRA environments

OA2500 PLUS-A vs. OA2500 PLUS

The OA2500 PLUS-A is identical to the OA2500 PLUS with one critical addition: the audible alarm. This alarm provides an active notification when the HEPA filter approaches end-of-life, ensuring your containment never runs on a failed filter without your knowledge. For environments where filter integrity is non-negotiable — including hospital construction and ICRA zones — the audible alarm adds a critical layer of safety compliance.

Applications

• Mold remediation and containment
• Asbestos and lead abatement
• Construction and demolition dust control
• Renovation and remodeling projects
• ICRA infection control in healthcare settings
• Water damage restoration drying support
