The Dri-Eaz HEPA 500 Carbon Pre-Filter now equips the HEPA 500 to capture a wide variety of volatile organic compounds (VOCs), including soot and smoke, food odours, fumes from paint and paint thinners, sewer odours, and many other compounds. No modification of the DefendAir is required - users simply place the new carbon filter inside the cabinet in front of the HEPA filter and then re-secure the cover. The capacity of the carbon filter will vary widely depending on conditions, but it should be replaced when its effectiveness declines.
Features:
- Captures a wide variety of volatile organic compounds (VOCs & MVOCs).
- Utilises Extruded Activated Carbon-carbon pellets, manufactured to a uniform size, to help ensure maximum airflow and maximum contact.
- Works by adsorption, carbon filtration’s natural ability to attract and hold gas and liquid molecules on its surface.
- 450g of carbon has over 450000 square meters of available surface – equivalent to the area covered by more than 60 football fields.
- Media: Utilises Extruded Activated Carbon - 1kg of carbon pellets, manufactured to a uniform size, to help ensure maximum airflow and maximum contact.
- Filter Frame: Sturdy frame won't flex or leak.
The DefendAir HEPA 500 can be configured with a variety of filters to suit your specific air scrubbing requirements. Use the chart below to find the best filtering configuration for the job at hand.
| Filtering Application | First filter position | Second filter position | Final filter (HEPA) |
|---|---|---|---|
| Clean water loss air scrubbing. For a relatively clean environment. | (no filter necessary) | 2nd Stage Pre-Filter (F271 or AC36F2) | HEPA filter (F321) |
| Standard air scrubbing. For environments with higher particle loads, such as construction or remodelling sites. | 1st Stage Pre-Filter (F270) | 2nd Stage Pre-Filter (F271 or AC36F2) | HEPA filter (F321) |
| First pass efficiency air filtration. For use with a negative air setup during remediation of high-risk contaminants and/or when DOP testing is required. | (no filter necessary) | DOP Pre-Filter (F415) | HEPA filter (F321) |
| Odour control and air filtration. For the removal of volatile organic compounds (VOCs), food odours, fumes from paint and paint thinners, sewer odours, and many other noxious odours. | Activated Carbon Filter (F397) | 2nd Stage Pre-Filter (F271 or AC36F2) | HEPA filter (F321) |
Filter Descriptions
- 1st Stage Pre-Filter (F270). Synthetic fibre filter media rated at 10% efficiency. Captures the largest particles to help extend the life of the higher efficiency filters inside. More info.
- 2nd Stage Pre-Filter (F271 or AC36F2). Synthetic fibre filter media rated at 30% efficiency. Captures larger particles to help extend the life of the HEPA filter. More info.
- DOP Stage 2 Pre-Filter (F415). Use of the DOP filter ensures laboratory-rated performance for sensitive jobs requiring first-pass HEPA filtration. More info.
- Activated Carbon Filter (F397). The activated carbon filter allows the removal of a wide variety of compounds, including volatile organic compounds (VOCs), food odours, fumes from paint and paint thinners, sewer odours, and many other noxious odours. Combining activated carbon filtration with HEPA filtration is especially effective in removing airborne soot particles and the odours they create. More info
- HEPA filter (F321). The HEPA filter has an efficiency rating of 99.97% against 0.3-micron oily aerosol particles. The HEPA filtration standard was developed in the 1940s to control radioactive dust particles in U.S. nuclear laboratories. More info.
N.B. - This filter is interchangeable with the XPOWER X-3400 Air Scrubber Carbon Filter
