DESCRIPTION

The KOOLTRONIC EMI/RFI shield conforms to the latest technology in attenuation of electromagnetic interference. The KPR Series combines this
shield with Standard Twin Packaged Blowers. In addition, the shielded front end can be incorporated into the entire broad line of KOOLTRONIC
Packaged Blowers, as an option, with a few dimensional changes. This same front end can also be used as an enclosure accessory. See EMI-Shielded
Filter-Grille Assemblies.

KOOLTRONIC achieves a high degree of EMI attenuation by the use of proven techniques and scrupulous production and quality controls. The honey­comb element and copper and tin-plated iron wire gasketing are sandwiched between a plated unitized steel frame and the plated flange welded to the
cabinet. These are rigidly clamped in place with precision-torqued Allen head cap screws. This permits high clamping pressures for maximum EMI
attenuation without distortion. The use of metallic chromate finish on the steel frame and corrosion-protected aluminum honeycomb provides uniform
high attenuation and minimum internodal resistance. No conductive plastics are used. A full mounting flange provides a continuous conductive surface
for interface with the user’s cabinet.

KOOLTRONIC also offers a full line of EMI-Shielded Filter-Grille Assemblies, independent of the blower package. These assemblies can be used at
remote inlet or discharge locations, for EMI-protected air paths.

EMI/RFI-shielded fronts, in packaged blowers or used separately, do not reduce air delivery.

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
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.

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.
