NEGATIVE PRESSURE HEPA FILTER SYSTEM FOR ISOLATION ROOM

NEGATIVE PRESSURE HEPA FILTER SYSTEM FOR ISOLATION ROOM

The HEPA UNIT is a portable, self-contained high efficiency particulate air (HEPA) filtration system designed to easily and economically create a negative pressure isolation room that will meet OSHA and CDC TB guidelines.
The HEPA Filtration Unit 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 COVID 19, TB, SARS or other infectious diseases.
As a recirculating unit, the HEPA Filtration Unit has a powerful motor/blower that can deliver up to 800 cubic feet per minute (CFM) or 1360 m3 /hr to provide a large number of room air changes per hour to minimize the spread of airborne diseases to patients and healthcare 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 12 in. (305 mm) collar located on the top of the equipment.
As a Partial Exhaust system: Same HEPA filtration unit can be used as a partially exhaust and major recirculation unit. This means that, about 10-20% of the total air can be exhausted into the environment and the rest of the air is recirculated. In this type of setup a negative pressure is created in the room along with hepa filtration in the same area. In layman’s terms, it means that although negative pressure is maintained in the room still the unit is able to maintain cleanliness level in the room.
As a positive pressure system, the HEPA filtration unit can be optimized to intake required amount of fresh air and mix it in the recirculated air. In a typical clinical (hospital) setup, where cleanliness levels are of utmost priority positive pressure is maintained in the room using small percentage of fresh air and mixing in the recirculated air.
As a fresh air filtration unit, the HEPA filtration unit can be used as a 100% fresh air unit which along with providing cleanair, also provides ventilation. This setup is usually designed for households, gyms, shops, showrooms etc.

The HEPA filtration unit consists of high grade H14 mini pleat filters.

• Low Cost Isolation Room: This system is an easy and economical solution for creating a negative pressure, isolation room. Simply roll the HEPA filtration unit into a standard room, connect flexible ducting to the 6 in. (150 mm) collar on the side of the unit for partial exhaust or to the optional 12 in. (305 mm) flanged collar for total exhaust and vent the purified air to the exterior through a window or wall.
• Flexible Applications The versatile HEPA Filtration Unit can be used as a clean air recirculating unit, a positive pressure 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 room.
• Adjustable Airflow With speeds ranging from 300 to 800 CFM (510 to 1360 m3/hr), The HEPA filtration unit provides effective air filtration for a wide variety of room sizes.
• Room Air Changes Per Hour The HEPA Filtration System is capable of providing up to 27 room air changes per hour (ACH) in a typical 15 x 15 x 8 ft (4.5 x 4.5 x 2.4 m) patient room or up to 12 ACH for rooms up to 4,000 cubic feet (113 cubic meters).
• Working Principle Room air, along with airborne contaminants, are drawn into the intake grille at the bottom of the equipment, while the purified air is discharged at the top of the HEPA Filtration Unit, which generates a sweeping air circulation pattern with adequate "reach" to optimize the clean breathing zone for patient and staff.
• Small and Portable The HEPA Filtration unit can be rolled from one room to another and easily fit into areas with limited floor space (Wheels with lock)
• Simple Maintenance Both HEPA filter and prefilter are easily accessible for replacement by authorized personnel.
• Quiet Operation 52 dBA on low, 56 dBA on medium and 60 dBA on high speed measured 30 in. (762mm) from face of the unit.
• Filter HEPA Filter Aluminum Framed HEPA type, with a minimum efficiency of 99.99% @ 0.3 micron, aerosol challenged (zero probed). Airflow sensor indicates when the filter needs changing. Prefilter 10 MICRON Pre Filter (G5 grade) Washable type Fine Filter 5 MICRON Fine Filter (F8 Grade) Washable type.
• UV light Providing intensity of >40 µW/cm2 at HEPA filter surface (hour meter provided for extra charge on request)
• Airflow Speed Control Adjustable airflow speed control from 300 – 800 CFM ±10%.
• VIRUS BURN OUT HEATER (OPTIONAL) An optional 2KW heater can be installed with controller in the same model (at an extra charge)
• Filter Health Indicator Indicator for HEPA filter is provided. It turns on red when the filter is choked, its green if the filter is healthy
• Warranty 1 year against any manufacturing defects
