DR. AIRE Electrostatic Precipitator Cleaning Guide

Regular cleaning is critical to maintaining stable purification efficiency, extending service life, and eliminating fire risks for the DR. AIRE Electrostatic Precipitator (ESP). Below is the standard cleaning procedure and essential precautions.

Standard Cleaning Steps

1. Prepare the alkaline cleaning solution

Mix sodium hydroxide (caustic soda) with water at the required ratio to prepare the dedicated ESP cleaning solution.

2. Cut off all power completely

Turn off the main power supply of the equipment, open the electrical control box, and loosen the fixing knobs. Ensure the equipment is fully powered off before any operation.

3. Discharge static electricity and remove the collector cell

Use a screwdriver to fully discharge residual static electricity on the positive and negative plates of the collector cell. Wear rubber gloves, hold both sides of the collector cell steadily, and take it out carefully.

4. Soak the collector cell

Place the collector cell horizontally into the prepared alkaline solution and soak it for 3 to 5 minutes to dissolve accumulated oil grease.

5. High-pressure rinsing

Take out the soaked collector cell and thoroughly rinse off all oil dirt and cleaning solution residue using a high-pressure water gun.

6. Air dry and reinstall

Place the cleaned collector cell in a ventilated, dust-free environment for natural air drying. After fully dried, reinstall the collector cell into the ESP following the original assembly structure.

Cleaning & Maintenance Precautions

1. Avoid fire hazards from clogged filters

The high-low voltage collector cell and pre-filter are core components of the ESP. Long-term operation without regular cleaning will cause heavy accumulation of oil and dust, which may lead to blockage and potential fire risks. Timely cleaning is mandatory for operational safety.

2. Follow a fixed cleaning cycle

The filter system and collector cell require routine cleaning every 20 days. After alkaline cleaning, the collector cell must be completely dried to ensure unobstructed airflow and stable purification performance. The equipment shell shall be cleaned regularly, with more frequent cleaning required in dusty environments.

3. Proper storage when idle

If the equipment will not be used for a long time, clean and dry it thoroughly first, then store it in a dry and well-ventilated place. Keep the equipment waterproof and moisture-proof to avoid performance degradation or component damage caused by moisture regain.
