NEC 24J39531 Air Filter 4 pk for PA500X PA550W PA500U PA600X

4-pack air filters for NEC PA projectors

This four-pack of replacement air filters fits select NEC PA series projectors including PA500X, PA550W, PA500U and PA600X models. Each filter blocks dust from reaching the optical engine and cooling path. The pack supplies enough filters for multiple scheduled changes.

For owners of listed NEC and Ricoh projectors

These filters suit technicians and AV managers maintaining the compatible NEC PA and Ricoh PJ-WX6170N or PJ-X6180N units. They do not fit projectors outside the listed model range, so buyers with different hardware should verify compatibility before ordering.

Multi-pack simplifies routine maintenance

With four filters in one box, you can follow the manufacturer guidance to clean every three months and replace at each lamp change without reordering. Ready stock reduces downtime and helps sustain consistent airflow and cooling performance.
