DESCRIPTION

KOOLTRONIC Double Centrifugal Blowers are designed to provide greater airflow than the related single blower series, in the same types of low to
moderate static pressure applications. Similarly, they are easily installed and operate with equal effectiveness in any mounting orientation.

Eleven models comprise the series, offering a choice of sizes and capacities to satisfy a wide variety of cooling requirements. Together, single and double
centrifugal blowers are the backbone of forced convection air cooling.

These Double Centrifugal Blowers and the Quadruplex Centrifugal Blowers are the exclusive air movement components in virtually all KOOLTRONIC
Packaged Blowers, Heat Exchangers and Air Conditioners.

STANDARD FEATURES

RUGGED CONSTRUCTION: Precision-engineered heavy-gauge steel construction insures blowers stand up under tough applications.

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. NOTE:

Some 230 Volt models may not be available or minimum purchases may apply. Contact Kooltronic for information.

LEADS: 12'' [304.8mm] (minimum) power and ground leads. Special lengths and/or plugs available.

ACCESSORIES AND OPTIONS*

AIRFLOW SWITCH: Protects equipment against damage caused by loss of cooling airflow by activating an alarm or turning off power. The switch can be

mounted on any suitable surface which allows the stainless steel air vane to be placed in the critical airstream. This switch is a single-pole double-throw
type, with normally open and normally closed contacts. To order integrated airflow switch add -XX10 to model number. To order as external accessory, see
Kooltronic website.
