Portable Air Safety Systems (PASS) 1600ISO
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.

Important. For recirculation mode the room pressure fault alert must be overridden. Press the
Audio Alarm Cancel button on the Display Panel for 5 seconds to cancel the pressure fault
alert. An R will appear in the Digital Display next to the Room Pressure to indicate operation is
in the Recirculation mode.
2.4.2 For a negative pressure application, open the air flow damper on the smaller port on the
EXHAUST end until about 1/3 open. Fully close the intake side’s smaller port damper.
2.4.3 For a positive pressure application, open the air flow damper on the smaller port on the
INTAKE end until about 1/3 open. Fully close the exhaust side’s smaller port damper.
•Attach the air supply and return ducting according to your selected configuration (see
examples below).
•Plug in the unit, turn the power switch to ON, and adjust the blower speed control for the
desired airflow (0 to 1600 CFM).
•Observe the pressure reading on the digital display and readjust the damper to achieve
the desired pressure differential. If the desired pressure differential cannot be achieved
