TPC PC4 Series Air Filter Regulator Lubricator – Efficient Air Treatment Solution

The TPC PC4 Series Air Preparation Unit is a compact and reliable compressed air treatment solution that integrates three essential functions: filtration, pressure regulation, and lubrication (FRL – Filter, Regulator, Lubricator). Designed for industrial pneumatic systems, the PC4 Series ensures clean air supply, stable pressure control, and proper lubrication for downstream equipment. With its robust construction and flexible configuration options, the TPC PC4 Series is widely used in automation systems, manufacturing lines, and various pneumatic applications.

1. Introduction to TPC PC4 Series

The TPC PC4 Series is a compact air treatment unit designed to improve the quality and stability of compressed air systems. It integrates three essential functions in a single assembly known as FRL (Filter – Regulator – Lubricator).

This combination unit removes contaminants, regulates air pressure, and provides lubrication to pneumatic components. As a result, it enhances system reliability and extends the service life of pneumatic equipment.

2. Overview of FRL Units

In pneumatic systems, an FRL unit ensures that compressed air is properly conditioned before reaching downstream equipment.

The three main components include:

• Filter – removes dust, moisture, and particles from compressed air
• Regulator – maintains a stable and controlled air pressure
• Lubricator – introduces a fine oil mist to lubricate pneumatic devices

Together, these components improve performance and protect pneumatic equipment.

3. Key Features of TPC PC4 Series

Compact Integrated Design

The PC4 Series combines filtering, pressure regulation, and lubrication in a single compact unit, reducing installation space.

High Filtration Efficiency

The unit provides 5 µm filtration accuracy, effectively removing small contaminants from compressed air.

Accurate Pressure Control

The regulator allows pressure adjustment within 0.05 – 1.0 MPa, ensuring stable system operation.

Automatic Lubrication

The lubricator supplies controlled oil mist to pneumatic tools and actuators, minimizing friction and wear.
