DESCRIPTION
KOOLTRONIC Duct Supply Blowers generate large volumes of cooling air in limited spaces. They
deliver filtered air from either one or two side discharge ports to cool every component in an
electronics system by means of a single centrifugal blower wheel. The wheel, driven by a powerful,
precision ball-bearing motor, delivers cooling air to side ducts, built into the enclosure, for
distribution where needed. While the motor operates at a quiet, life-extending lo w speed, the pressure
characteristic of the large, narrow wheel far exceeds that of conventional blower units often used to
supply duct systems.
Filtered air is delivered directly from the wheel into the duct, with no twists or turns. The steep
performance curves demonstrate that duct and other frictional losses cannot hamper adequate air
delivery when a unit of this design is specified as the cooling source.

STANDARD FEATURES
RUGGED CONSTRUCTION: Precision-engineered heavy-gauge steel construction insures blower will stand up under tough industrial applications.
EIA-notched flanges extend 17
BAKED POWDER FINISH: Durable, baked-on gray powder finish is standard. Other finishes are available.
PRECISION BALL-BEARING MOTORS: All motors, whether permanent split capacitor or shaded pole, are UL/CSA Recognized, and include
automatic-reset thermal overload protection. Designed for low temperature rise, KOOLTRONIC motors are also cooled by the blowers' intake air, for
maximum motor life. All motors meet Federal Specification CC-M-1807A, and include double-sealed or double-shielded precision ball bearings which
meet Federal Specification FF-B-171A. Special permanent lubricants perform over a broad temperature range: -20ºF (-28.9ºC) to 250ºF (121.1ºC).
Consult KOOLTRONIC for motors designed to meet military or extreme environmental specifications.
POWER: 115 VAC or 230 VAC, 50/60 Hz is standard. For multi-phase power, other voltages and frequencies or brushless DC applications, consult
KOOLTRONIC.
GRILLE:All units include attractive 19
and complies with OSHA and UL safety standards.
PERMANENT FILTERS: Designed to last the life of the unit, the filters included with all packaged blowers consist of a multi-layer grid of sturdy,
corrugated aluminum in a one-piece aluminum frame. Adhesive coated to trap particulate matter, they are easy to remove, wash and treat with
KOOLTRONIC A-16, an adhesive-rejuvenating spray. Filters must be kept free of accumulations, to prevent reduction or loss of performance and/or
damage to equipment.
POWER CORD: All 115 VAC, 50/60 Hz units are supplied with a minimum of 36''[914.4mm] type SJT three-wire cord with molded plug included,
internally grounded and securely locked to the case by a strain relief bushing. 230 VAC, 50/60 Hz blowers are supplied without a plug. Special lengths
and/or plugs are available.
EXHAUST GUARDS: Included on all packaged blowers.

AIRFLOW SWITCH: See accompanying literature for more information.
EMI/RFI SHIELDING: See EMI/RFI-Shielded Twin Packaged Blowers.
FILTER RECOATING ADHESIVE: This compound is a superior product for recoating all permanent filters after washing. The adhesives penetrate
dirt layers to keep the filter surface tacky for longer effective performance between washings.
Part No. A-16 - one pint container.
FILTERS FOR REPLACEMENT: All KOOLTRONIC filters consist of a multi-layer grid of sturdy corrugated aluminum, securely held in a one-piece
aluminum frame. Filters are required wherever air is drawn into an electronics enclosure or related cooling equipment to keep internal parts as clean as possible.
A non-drying adhesive coating traps a high percentage of particulate matter. These washable, reusable filters are designed to last the life of the cooling
unit. Replacements are available for those which become damaged or otherwise non-serviceable.

GRILLE ASSEMBLIES: These assemblies are ideal for venting applications on the enclosure. These attractive grilles are made of mirror-finish
stainless steel. All are 19''[482.6mm] wide. They are 65% open, comply with OSHA and UL safety standards, and include knurled captive fasteners for
easy attachment and removal.
