OPERATING THE UNIT

BEFORE OPERATING THE UNIT

Inspect and tighten any HEPA filter retaining bolts that may have loosened during transportation. Inspect the

filters for any material or structural damage prior to use and replace any damaged filters before operating the

unit. When removing any filters prior to operation, always put them back in place with the airflow indicator on

the filter housing oriented in the proper direction (if applicable).

As with any air filtration system, external airflow losses not attributable to the air filtration unit will reduce the

airflow of the system. The following recommendations can minimize airflow losses created by external static

resistance.

1. Always use the minimum length of ducting possible with the fewest possible number of turns and bends.

2. Rigid metal ducting creates less turbulence and consequently less airflow loss than flexible ducting.

Regardless of the type of ducting used, rigid, "sweep-type', radiused connections should be used for all

turns and bends.

3. If flexible ducting is used, it must be kept as taut as possible to avoid flattening.

MODES OF OPERATION

1. Negative Pressure – used to help ensure that airborne contaminants do not escape from a contained area

by maintaining negative (lower) air pressure within that area compared to adjacent areas. Any air leakage

will be an inflow of external air, not an outflow of contaminated air. To ensure that the proper pressure

differential is maintained, the volume of HEPA-filtered air exhausted from the containment area must be

the greater of 10% or 100 CFM higher than the volume of air entering. This pressure differential can be

established by:

a. placing the unit inside the containment area and using it to push air out of the containment area.

Attach flex duct at the outlet collar and exhaust the HEPA-filtered air outside of the containment

area according to regulations – outdoors or another location within the building.

b. placing the unit outside of containment area and using it to pull air out of the area. Attach flex duct

between the inlet collar and the containment area.

2. Recirculation – used to reduce concentrations of airborne contaminants in a room or area by continuously

cleaning the air and exhausting it back into the same room or area.

3. Positive Pressure – used to help prevent airborne contaminants from entering a containment area by

maintaining positive (higher) pressure within that area compared to adjacent areas. Any air leakage will be

an outflow of clean air, not an inflow of external air. To ensure that the proper pressure differential is

maintained, the volume of HEPA-filtered air supplied to the area must be the greater of 10% or 100 CFM

higher than the volume of air exhausted. This pressure differential can be established by:

a. placing the unit inside the containment area and using it to pull air into the containment area.

Attach flex duct between the inlet collar and a location outside of the containment area.

b. placing the unit outside of containment area and using it to push HEPA-filtered air into the area.

Attach flex duct at the outlet collar and exhaust the HEPA-filtered air inside of the containment

area.

If the room air filtration units are being used to create and maintain a negative/positive pressure condition, the

pressure differential between the negative/positive room and the environment outside the room should be
