Product Description

Restore Performance. Protect Uptime.

The FS-Curtis FSK-NX30-37TUK Tune Up Kit is the OEM rebuild package designed specifically for:

  • NX30 (40 HP)

  • NX37 (50 HP)

Over time, critical control components such as the inlet valve, thermostatic valve, and minimum pressure valve (MPV) experience wear. This tune up kit restores proper airflow control, oil temperature regulation, and system pressure stability.

This kit replaces the previous part number FSK-8NX30-37.

Component Part Number Qty
Inlet Valve 2104050162 1
Inlet Valve O-Ring 2111010483 1

Everything required to refresh critical airflow and temperature control components.

Why a Tune Up Kit Matters

In 40–50 HP rotary screw compressors, these components directly impact:

  • Proper air intake regulation

  • Stable system pressure

  • Correct oil temperature control

  • Reduced energy waste

  • Protection of the airend

  • Overall compressor efficiency

A failing inlet valve can cause loading issues.
A worn MPV can impact pressure stability.
A degraded thermostatic valve can lead to improper oil temperature and reduced compressor life.

Replacing these parts proactively helps prevent costly downtime and performance loss.
