Description

The DAYTON 6K030 is a belt-drive fan/blower motor built for HVAC/R duty where reliable, continuous operation and easy service matter. Its split-phase design provides smooth start-ups, while a robust 56Z rolled-steel frame with open-dripproof (ODP) cooling keeps the motor compact and well-ventilated in equipment rooms. With 1/3 HP, 1725 nameplate RPM, 115 VAC, ball bearings, and a stout 1.35 service factor, this motor is an excellent choice for belt-driven blowers and fans. The reversible rotation (wired for CCWSE/CWLE) and cradle base simplify field replacements, and the included 1/2″→5/8″ bushing helps match common pulley/bore combinations.

Features

• HVAC/R belt-drive duty: ideal for supply/return fans, cabinet blowers, evaporative coolers
• Split-phase, single-speed: smooth starts without a run capacitor
• Reversible rotation: wire for CCWSE/CWLE to match your pulley orientation
• Ball bearings: longer life and higher belt tension tolerance vs. sleeve designs
• ODP enclosure: efficient cooling for indoor mechanical spaces
• Cradle base mount: easy belt alignment and tensioning in tight cabinets
• High Service Factor (SF 1.35): extra thermal and load margin for tough days
• Auto thermal protection: built-in overload reset for safety
• Includes 1/2″→5/8″ bushing: flexible pulley fit-up

Cross-Referenced Models

• Replaces/alternate for Dayton 4C445 (blower assembly this motor commonly pairs with; verify pulley/rotation and amperage)

Comparable Motors (match on HP/RPM/Frame/Mount)

• NBK Parts: 56Z 1/3 HP, 115V, 1725 RPM, ODP, cradle base, ball bearings, reversible CCWSE/CWLE (select by shaft length and FLA)
• Century / Regal: C566 series (1/3 HP, 1725 RPM, 56Z, ODP, cradle)

  (Compare shaft diameter/length, SF, amps, and base footprint before substituting.)

What This Motor Can Be Part Of

• Belted blower assemblies (forward-curved housings with adjustable pulley)
• Filtration & HEPA cabinets (indoor clean-air duty)
• Custom fan skids with vibration isolation, adjustable motor bases, and guards
  Accessories often paired: fixed/adjustable pulleys, matched V-belt, adjustable cradle/base plate, belt guard, AMCA-style inlet cone, starter or disconnect.

Installation Notes (Quick)

• Set pulley for required RPM/CFM; align sheaves and tension belts per manufacturer specs.
• Wire for the required rotation (use CCWSE/CWLE convention) and confirm airflow before finalizing guards.
• Verify line voltage and FLA (≈5.8 A) after run-in; ensure ODP is acceptable for the location (dry, clean, indoor).
• Maintain bearing alignment; re-tension belts after the first few hours of runtime.
