High-Efficiency Airborne Contaminant Control & Negative Pressure

Restoration jobs involving mould spores, sewage backups, fire soot, or fine construction dust demand strict containment to protect workers and occupants. The Dri-Eaz DefendAir HEPA 500 Air Scrubber provides high-volume, continuous air purification and negative pressure creation. Air is drawn through multi-stage media to trap bioaerosols and particulate matter before recirculating clean air or venting contaminated air safely outside.

Designed with restoration contractors in mind, its compact footprint, lightweight design, and stackable casing allow easy transport and setup in tight residential or commercial job sites.

Key Benefits & Features:

• True HEPA Filtration: Captures 99.97% of 0.3-micron airborne particulates—including mould spores, fine dust, fungi, and particulate smoke.

• Variable Airflow Control: Turn the variable speed knob to set airflow anywhere from 250 CFM up to 500 CFM to match job site requirements.

• Daisy-Chain Auxiliary Outlet: Integrated auxiliary power outlet allows up to 3 units to be connected on a single circuit (up to 1500 CFM combined output).

• Built-In Microban® Protection: Rotomolded polyethylene housing incorporates antimicrobial protection to prevent the growth of odor-causing bacteria and mould on the unit.

• Filter Change Indicator Light: Signals automatically when the primary HEPA filter is loaded and requires replacement.

• Versatile Ducting Options: Built with a ductable 12-inch (30.5 cm) inlet and 8-inch (20.3 cm) layflat outlet for negative air setup.

• Modular Filter Upgrades: Expandable with optional Activated Carbon Filters for odor/VOC absorption or DOP Filters for first-pass containment testing.
