THE ISOL-AIDE Ventilation / Filtration Unit (VFU) is a patented, environmental control unit that has become the key component of safer workplaces nation-wide. Developed originally for "High-Hazard" procedures performed in the ISOL-AIDE Sputum Induction Chamber, the VFU offers the proven technology of that medical device to those confronted with the dangers posed by airborne micro-organisms in a variety of other settings.

The VFU can achieve negative room pressure, dilution and a low mixing factor within a room, without costly changes to the heating and cooling system.

Three Stage Protection - The ULPA Advantage
Air is first prefiltered, irradiated by UV light and final filtered by an ULPA filter which is 99.9995% efficient for particles .12 micron or larger. ULPA filters are capable of filtering particles less than half the size and at an efficiency rate that is 10 times greater than a HEPA filter.

Thoroughly Tested to Remove Bacterial Aerosols
Published, comprehensive testing demonstrates the VFU's ability to remove bacterial aerosols from the air. This permits safe recirculation within the facility or outdoor exhaust regardless of proximity to people or open windows.

Automatic Room Pressure Control
Patented fan speed control maintains comfortable air flow levels during normal operation for improved compliance. Automatically increases air flow when doors are opened to maintain negative pressure and insure safety.

Local and Optional Remote Alarms
ISOL-AIDE constantly monitors filters, UV light, fan operation and entry or egress. Audible and visual alarms at the VFU signal trouble. An optional alarm panel can be remotely located or the VFU can be wired to signal a central building system.

Durable, Tamper Resistant Construction
The VFU cabinet is baked, epoxy painted steel, assembled with tamper resistant, Torx screws. A hidden override switch can be used to disable control panel.

Energy Efficient
ISOL-AIDE safely recirculates conditioned air within the facility rather than exhausting it out of doors. The patented fan speed control allows the fan to operate at low speed, with less energy consumption, until door is opened.
