Maintaining stable performance in a cleanroom environment requires regular equipment inspection and preventive maintenance. Recently, the technical service team from Shanghai Fengyi Cleanroom Technology Co., Ltd. conducted an on-site cleanroom equipment maintenance service for a customer.

The main tasks during this service visit included cleaning the pool water inlet to prevent blockage and providing technical training on air shower filter maintenance, including both pre-filters and HEPA filters.

This maintenance service helped the customer improve equipment reliability and ensure the cleanroom environment continues to meet strict cleanliness requirements.

On-Site Equipment Maintenance Overview

During the visit, Fengyi engineers first inspected the customer’s facility equipment and identified several areas that required routine maintenance.

The service focused on two important systems:

• Water pool inlet cleaning to prevent pipe blockage

• Cleanroom air shower filter maintenance training

By performing these tasks, the engineering team ensured that both the water circulation system and the cleanroom air filtration system remained in optimal working condition.

Water Inlet Cleaning to Prevent System Blockage

Over time, debris, dust particles, and sediment can accumulate around the water inlet of industrial pools, which may affect water circulation and reduce system efficiency.

To address this issue, Fengyi technicians performed a thorough cleaning process.

The maintenance work included:

• Removing debris and contaminants near the water inlet

• Inspecting the inlet structure and surrounding pipeline

• Ensuring smooth water flow

• Preventing potential system blockages

Regular water inlet cleaning and inspection is a simple but effective way to avoid equipment malfunction and reduce long-term maintenance costs.

Air Shower Maintenance Training for Cleanroom Operators

A cleanroom air shower is designed to remove dust particles from personnel before entering a controlled environment. If the air filtration system is not properly maintained, the cleanroom’s cleanliness level may be compromised.

During this visit, Fengyi engineers provided hands-on guidance for the customer’s staff on how to properly maintain air shower equipment.

Training topics included:

• Structure and working principle of air showers

• Daily inspection procedures

• Filter maintenance and replacement

• Operational best practices

This training helps operators perform routine maintenance independently and maintain consistent cleanroom performance.

Pre-Filter Maintenance in Air Shower Systems

The pre-filter (primary filter) serves as the first stage of air filtration. Its main function is to capture larger dust particles and protect the HEPA filter from excessive contamination.

During the training session, Fengyi engineers demonstrated:

• How to inspect dust accumulation in the pre-filter

• Cleaning and replacement procedures

• Recommended inspection intervals

• Methods to maintain stable airflow

Proper pre-filter maintenance can significantly extend the lifespan of the entire air filtration system.

HEPA Filter Maintenance and Inspection

The HEPA filter plays a critical role in maintaining cleanroom air quality by removing extremely fine particles.

Fengyi engineers explained several important aspects of HEPA filter maintenance, including:

• How to detect filter performance changes

• Monitoring pressure differences

• Correct installation procedures

• Identifying signs that require filter replacement

Routine inspection and proper handling of HEPA filters help ensure that the cleanroom environment remains compliant with industry standards.
