Email Air Handling Negative Air Fan Filter Modules are designed for use in applications where critical contaminants must be isolated. Typically used for asbestos removal.
The Negative Air Fan Filter Module is manufactured in Australia to conform with the performance requirements of AS2252.6. The robust cabinet houses a fan, pre-filter and a HEPA filter. This combination ensures the removal of airborne contamination by air drawn in by the fan and passing through the filters.
The HEPA filters are individually tested on a NATA accredited Hot DOP test rig to AS2252.6 and filter efficiency is always guaranteed. Hot DOP testing is an essential part of HEPA filter manufacture since only Hot DOP creates a fog of 0.3 micron particles to challenge the filters efficiency. To pass inspection each filter must achieve a minimum efficiency of 99.99%. The module HEPA filter is designed and tested to supply 566 l/s at an initial resistance of 250 Pa.
