The Envirco Hospi-Gard IsoClean is a portable, self-contained high efficiency particulate air (HEPA) filtration system designed to easily and economically create a negative pressure isolation room/environment that will meet OSHA and CDC TB guidelines. The IsoClean can be used as a positive pressure clean air recirculating system in clinics, waiting rooms, hospital emergency rooms and other confined areas or as a partial or complete exhausting system to create a negative pressure isolation room for possible use with patients known or suspected of having TB, SARS or other infectious diseases. As a recirculating unit, the IsoClean 's powerful motor/blower can deliver from 560 CFM (951 m3/hr) up to 800 CFM (1359 m3/hr) to provide a large number of room air changes per hour to minimize the spread of airborne diseases to patients and health care workers. As a negative pressure unit, the air passing through the HEPA filter is cleansed of 99.99% of particles as small as 0.3 micron and may be exhausted directly to the exterior through a window, or through a wall simply by connecting flexible ducting to the 6 in. (152 mm) collar located on the top of the IsoClean . The Hospi-Gard IsoClean filter contains 220 square feet (20.4 square meters) of media to extend its usable lifetime before filter loading occurs, resulting in decreased cost and fewer filter changes. This product has limited warranty of 1 year. Standard Features Low Cost Isolation Room: An easy and economical solution for creating a negative pressure, isolation room. Simply roll the IsoClean into a standard room, connect flexible ducting to the 6 in. (152mm) collar on the top of the unit for partial exhaust or to the optional 8" (204 mm) flanged collar for total exhaust and vent the purified air to the exterior through a window or wallFlexible Applications: The versatile IsoClean can be used as a clean air recirculating unit, a negative pressure unit or as a split system to create both negative pressure and clean air recirculation by simultaneously exhausting some of the air out while recirculating the remainder back into the roomSmall and Portable: The IsoClean can be rolled from one room to another and easily fits into areas with limited floor spaceRoom Air Changes Per Hour: Provides up to 24 room air changes per hour (ACH) in a typical 18 x 12 x 8 ft (5.5 x 3.7 x 2.4 m) patient room or up to 12 ACH for rooms up to 3,900 cubic feet (100 cubic meters)Low-High Clean Air Circulation Pattern: Room air, along with airborne contaminants, is drawn into the intake grille at the bottom while the purified air is discharged at a high velocity from the exhaust grille located at the top of the IsoClean to generate a sweeping, low-to high air circulation pattern with adequate "reach' to optimize the clean breathing zone for patient and staffSimple Maintenance: Both HEPA filter and prefilter are easily accessible for replacement by authorized personnel.
