Everything required to refresh critical control components in your NX compressor.

Why a Tune Up Kit Is Important

In 25–30 HP rotary screw compressors, these components directly affect:

• Proper air intake regulation

• Stable system pressure

• Correct oil temperature management

• Reduced energy waste

• Airend protection

• Overall compressor efficiency

A worn inlet valve can cause improper loading and unloading.
A failing MPV can impact pressure stability.
A degraded thermostatic valve can cause improper oil temperature, reducing compressor life.

Proactive replacement prevents expensive failures and production downtime.
