CAS Rotary Screw Compressor Cooling Fan Blade #IAT-026034C441
The cooling fan pulls air through the compressor's cooler so oil and discharge temperatures stay in range. This is the exact fan Compressed Air Systems documents for its 5–15 HP open rotary screw platform: part #IAT-026034C441 is the listed cooling fan in CAS's own 5–15 HP NK31 120-gallon horizontal parts breakdown — the same breakdown that carries the NK31 airend.
A cracked, loose, or bent fan blade shows up fast — rising temperatures, tripped safeties, and a compressor that won't stay loaded. Ordering the exact part number, instead of eyeballing a 'similar' blade, is what keeps shroud clearance and airflow right the first time.

Compatibility & Fitment
CAS documents #IAT-026034C441 as the cooling fan on its 5–15 HP open rotary screw compressors — the NK31-airend, 120-gallon horizontal platform (the parts breakdown is linked above). If your unit is a different configuration, don't select by hub size alone: correct blade size and orientation also matter for shroud clearance and airflow. Call with your compressor model and the old fan's part number and we'll confirm before you order.
