1.1. Explanation of Terms
WARNING:
Indicates the possibility of injury to the patient,
operator, or technician if accompanying procedures

equipment if procedures are not followed.
NOTE:
Places emphasis on an operating characteristic or
important consideration.
1.2. Definitions
ATF
®
(Advanced Technology Fractionator) – The term used to describe the oxygen
concentrating module used in SeQual products.
ESD (Electro-Static Discharge) – The effect of small static electrical charges on printed
circuit boards and components.
LPM (Liters Per Minute) – typically referring to oxygen flow rate
OM (Oxygen Monitor) - Integra concentrators can be ordered with an integrated oxygen
monitor. When specified, a procedure may apply only to OM equipped units.
POD Assembly – Subassembly consisting of the front panel and user interface components
including the printed circuit board and oxygen-monitoring device.
Product/Product flow – Refers to the oxygen being produced.
Rated Flow - The flow rate for which that model of Integra was designed to operate as a
maximum continuous rate. The rated flow of an Integra E-Z 5 is five liters per minute. The
rated flow of an Integra E-Z 7 is seven liters per minute and Integra E-Z 10 is ten liters/minute.
Upgraded – It is the policy of SeQual Technologies to incorporate certain design
improvements into machines, which have been returned to the factory for inspection and/or
repair. References in this manual to serial numbers indicates that the particular feature or
function has been incorporated beginning with that serial number, and is being incorporated on
upgraded machines.
1.3. Introduction to the ATF
The SeQual Advanced Technology Fractionator (ATF
®
) module eliminates many of the parts found in
conventional pressure swing adsorption oxygen concentrators. It has been designed and constructed to
provide years of trouble free service. A quick inspection will reveal the absence of the product tank,
pressure regulator, and solenoid manifold found in conventional two-bed concentrators. The functions
of these devices are replaced by a single rotating valve, which ports gas movement within the ATF
module.
