1.0 Introduction
1.1 Overview
The Isolations Systems Inc. Portable Air Safety Systems (PASS) 1600ISO unit provides
portable air filtration for standalone use in any area requiring enhanced air quality.
The PASS-1600ISO is capable of providing the proper interior environmental air quality as
outlined by AIA, ANSI/ASHRAE Standard 62.1-2019, Ventilation for Acceptable Indoor Air
Quality and the Centers for Disease Control (CDC) guidance for air changes per hour (ACH).
The continuous filtering of the air protects the area from biological contamination.
The PASS-1600ISO patented filtration configuration incorporates two banks of germicidal
ultraviolet lamps directed at and irradiating each side of a HEPA filter. The patented technology
serves three purposes. First, it irradiates and kills the microbial airborne contamination that are
captured and contained on the HEPA filter media surface. The resulting effect is the HEPA filter
does not become an incubator for the growth of infectious agents that can spread infection by
secondary aerosolization. The second advantage of this configuration is the HEPA filter itself.
The filter is a micro fiberglass HEPA filter that is rated at a 99.97% efficiency removal rate for all
particles >0.1 microns. This includes all fungi, bacteria, and most viruses. Finally, very small
viruses >0.01 micron in diameter that could work their way through the HEPA instead are
irradiated with germicidal UV radiation. The residual time of the small virus being irradiated is
several orders longer than required to make the viruses non-viable.
