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. This
shielded front end can be incorporated into the entire line of Kooltronic Packaged
blowers, as an option, with few dimensional changes. This same front end can also
be used as an accessory.
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 a plated flange welded to the cabinet. These are 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.
For unusual or higher-level attenuation requirements, or special EMI/RFI problems,
consult our Engineering Department.

KOOLTRONIC also designs and manufactures a variety of packaged blowers to meet
unique specifications. We invite your inquiries about our modification and
