Dri-Eaz DefendAir HEPA 500


DefendAir HEPA 500
Powerful air scrubber and negative air machine

High efficiency air filtration, the maximum clean air rating from AHAM, and extreme versatility - all with a small footprint! The DefendAir HEPA 500 combines advanced clean air performance with the valuable features to help make the restorer's job easier

The DefendAir HEPA 500 uses HEPA filter media with an efficiency rating of 99.97% against 0.3-micron oily aerosol particles, and 250-500 CFM, the typical airflow level demanded on restoration jobs.

Product Features

  • Built-in Microban antimicrobial product protection to inhibit growth of bacteria, mold, and mildew
  • Advanced filtration technology
  • Daisy chain capability - link up to 3 units on 1 power outlet
  • Variable CFM on each unit - up to 1500 CFM per 15-amp circuit
  • Stackable, lightweight, and easily transportable

Maximum CADR
The HEPA 500 offers the assurance of the maximum Clean Air Delivery Rate (CADR), an official standard set by the Association of Home Appliance Manufacturers (AHAM). The HEPA 500 meets the maximum standard set by AHAM (450 CFM). Independent testing (using AHAM protocols) also verifies that the HEPA 500 exceeds AHAM standards by delivering 500 CADR.

Designed for Restoration
With user-friendly and versatile features, the HEPA 500 is ideal for handling indoor air quality needs on every restoration job. Any job that involves sewage, mold, or fire damage clearly involves significant amounts of particulates and smelly gasses - a direct result of the damage itself.  In a water damage restoration environment, the high-velocity airflow needed for drying can stir up particulates that have settled in carpet or on other materials. The HEPA 500 can address indoor air quality quickly and efficiently, and help restore any environment to a pre-loss condition - the ultimate goal of every restoration job.
