INTRODUCTION
1.0. Introduction
1.1. Description
The Hospi-GardIsoClean®and IsoClean®UV are portable, self-contained high-
efficiency particulate air (HEPA) filtration system specifically designed to provide a high-
velocity airflow pattern from the top face grille that creates a sweeping action to remove
airborne particulate. In addition to recirculating clean air, it can simultaneously exhaust
air out of the room to create negative pressure. An optional 8-inch exhaust collar is
available to convert the IsoClean®to a complete exhausting system.
Air enters the module through the intake grille located on the lower section of the unit.
The air is evenly drawn by the blower first through a prefilter and then through a HEPA
filter. The HEPA filter is 99.99% efficient at removing particles 0.3 microns and larger.
The air moves at a volume of 550 cubic feet per minute (CFM) on low, 700 CFM on
medium and up to 800 CFM on high to carry away airborne particulate generated by
activities within the room.
The IsoClean®UV offers the added benefits of ultraviolet irradiation of the particulate
caught on the HEPA filter surface and in the air prior to recirculation back into the room.
1.2. Features
•The Hospi-GardIsoClean®can be used as a total recirculating air system, as a total
air exhaust system (using the optional 8-in. exhaust collar) or as a split system with
partial air recirculation and partial air exhaust.
•The Hospi-GardIsoClean®can easily and economically convert a standard room
into a negative pressure, patient isolation room.
•Provides 27 air changes per hour in a typical patient room of 18 feet x 12 feet x 8 feet.
•The three-speed adjustable airflow control allows effective use in a variety of room
sizes.
•High discharge air velocity with a high-to-low airflow pattern assures adequate “reach”
and air circulation, preventing “short circuiting.”
•Quiet operation. 52 dBA at low, 56 at medium and 60 at high speed measured 30 in.
from face of unit.
•HEPA filter and prefilter are easy to replace.
