KB1000B & KB1000S Thin Fans

The KB1000B and KB1000S are extremely compact thin fans delivering 750 CFM of airflow, engineered to meet the demanding space constraints of modern industrial cooling systems. These versatile units support multiple mounting configurations and can be operated in either pressurization or exhaust mode, providing flexibility for diverse HVAC and climate control applications.

Both models feature rugged construction with a durable baked powder finish that resists corrosion and maintains appearance under harsh operating conditions. The integrated UL/CSA Recognized ball-bearing motors are available in either permanent split capacitor or shaded pole configurations, each equipped with automatic-reset thermal overload protection to prevent damage from unexpected temperature excursions. Kooltronic's motor design prioritizes longevity through low temperature rise operation, with intake air cooling further extending motor life during continuous duty cycles.

The fan motors and construction materials are specified for operation across an exceptionally broad temperature range from -20F to 250F, with special permanent lubricants ensuring reliable performance without seasonal maintenance. Each unit includes 12-inch minimum power and ground leads for streamlined installation, and all models carry UL Recognition status and a Declaration of Conformity to applicable CE Standards. A complete line of accessories is available to support custom installations and system integration requirements.
