High-Efficiency Electrostatic Air Purification Unit

Defaee High-Efficiency Electrostatic Air Purification Unit is a professional embedded air cleaning system engineered for industrial ventilation, commercial HVAC systems and specialized spaces. It integrates three core technologies: high-voltage electrostatic field dust collection, ionization sterilization and electrostatic precipitation, effectively removing airborne particulates, cooking fumes, dust, bacteria, viruses and odor molecules for deep air purification.

Featuring a modular embedded design, this unit can be directly installed in air ducts, air handling units (AHUs), fresh air units or dedicated purification spaces. It is widely used in industrial waste gas treatment, commercial building ventilation, cold chain preservation air management and greenhouse disease control, providing high-efficiency, low-energy and easy-to-maintain air purification solutions.

Constructed with an integrated stainless steel housing, the unit is durable and corrosion-resistant, adapting to harsh conditions such as high humidity, heavy oil fumes and high dust concentrations. Its core is the high-voltage electrostatic purification module paired with a pre-filter, delivering dual purification effects. Equipped with self-diagnosis and status display functions, it ensures stable and reliable operation for industrial and commercial applications.

Core Technology & Operating Principle

Core System Components

The purification system consists of four synergistic modules that form a complete air treatment process:

1. Stainless Steel Pre-filter: Features high strength, corrosion resistance and reusability. It preliminarily captures large dust particles, oil fume droplets and fiber impurities, preventing clogging of the electrostatic unit, extending core component life and reducing downstream purification load.

2. High-Voltage Electrostatic Field Unit: The core purification module comprising an ionization section and a collection section. The ionization section charges airborne particulates, oil fume molecules and microorganisms. Charged particles then enter the collection section and are adsorbed onto collector plates under electric field force. Simultaneously, the high-voltage electric field disrupts the cell membranes of bacteria and viruses, inactivating them.

3. Control Unit: Operates on a 220V AC power supply with a rated power of only 25W for ultra-low energy consumption. It integrates fault indicators, operation indicators and a power switch to display real-time operating status. In case of high-voltage abnormalities or short circuits, the fault indicator illuminates for quick troubleshooting.

Detailed Operating Principle

Contaminated air first passes through the stainless steel pre-filter, where large particles are intercepted to prevent wear and clogging of the core unit. The airflow then enters the ionization section of the high-voltage electrostatic field, where particulates and oil fume molecules are electrically charged, and the protein structures of bacteria and viruses are destroyed, rendering them unable to reproduce.

Charged particles subsequently enter the collection section and are adsorbed onto the surface of collector plates by electric field force. The purified air is discharged after secondary filtration, completing the entire process.

Unlike traditional filter-based purification, this technology eliminates the need for frequent filter replacements. Only regular cleaning of collector plates and the pre-filter is required to restore efficiency, significantly reducing long-term maintenance costs. Its low-power design also delivers substantial energy savings for continuous industrial and commercial operation.

Product Structure & Key Components

Overall Structural Design

The unit adopts an embedded modular structure with a stainless steel housing, offering corrosion resistance, high temperature resistance and oil resistance for harsh industrial environments. A metal handle on the top facilitates installation, removal and maintenance. The side-mounted power interface supports AC220V power supply for easy wiring. It can be directly embedded into air ducts or pre-reserved installation positions without additional space modification, ensuring a simple and efficient installation process.

Key Component Functions

1. Stainless Steel Housing: Stamped from high-quality stainless steel with a smooth surface that resists dust accumulation. It withstands corrosion from oil fumes, moisture and corrosive gases, extending service life. The sealed design prevents high-voltage electric field leakage, ensuring operational safety.

2. Stainless Steel Pre-filter: Multi-layer stainless steel mesh construction with uniform pores for efficient large-particle capture while maintaining excellent air permeability, minimizing airflow resistance. It is fully detachable and washable with water or detergent for repeated use, eliminating consumable costs.

3. High-Voltage Electrostatic Field Unit: Composed of ionization wires, collector plates and insulators. Collector plates are made of aluminum alloy with a smooth surface for easy cleaning and high adsorption efficiency. Ionization wires are made of molybdenum wire for stable electrical conductivity and long service life. High-temperature resistant insulators ensure safe operation and prevent electric leakage.

4. Control & Display Module: The panel features input voltage (AC220V), rated power (25W) and high-voltage warning labels, along with red fault indicators, operation indicators and a power switch. The unit automatically shuts down in case of faults to prevent safety hazards.

Key Product Advantages

High-Efficiency Dual Purification

The "pre-filter + high-voltage electrostatic field" dual purification system effectively removes multiple pollutants including PM2.5, oil fumes, dust, fibers, bacteria and viruses. It achieves ≥90% removal efficiency for oil fume particulates and ≥95% inactivation rate for bacteria and viruses, solving problems such as industrial oil fume pollution, workshop dust exceedance, ventilation system odors and mold growth in cold storage.

Ultra-Low Operating Costs

With a rated power of only 25W, it consumes significantly less energy than traditional filter-based purifiers, delivering substantial electricity savings for long-term operation. The core collection unit is washable and reusable, eliminating the need for frequent filter replacements and associated consumable costs.

Versatile Compatibility & Easy Installation

The embedded modular design allows direct installation in air ducts, AHUs, fresh air units, downstream of kitchen hoods or dedicated purification spaces without modification. The stainless steel housing can be custom-sized to seamlessly integrate with ventilation systems of different specifications. Installation is straightforward and can be completed without professional technicians.

Durable & Low-Maintenance

Stainless steel housing and aluminum alloy collector plates provide corrosion, high temperature and oil resistance for complex working conditions. High-quality core components ensure long service life and low failure rates. Both the pre-filter and collector plates are detachable and can be cleaned with water to restore efficiency, requiring no professional tools or specialized maintenance.

Safe & Reliable Operation

Equipped with high-voltage warning labels and a self-diagnosis system, the unit automatically shuts down in case of high-voltage abnormalities, short circuits or electric leakage. The insulated sealed design prevents external electric field leakage, ensuring safe operation in industrial workshops, commercial kitchens, cold storage and greenhouses.

Installation & Maintenance Instructions

Installation Precautions

1. Verify that the on-site power supply matches AC220V/50Hz before installation to prevent equipment damage.

2. Install the unit horizontally in the air duct or pre-reserved position, ensuring the airflow direction matches the inlet side of the unit.

3. Ensure a tight seal between the unit and ductwork to prevent air leakage. Reserve sufficient space for disassembly and maintenance.

4. Avoid collision with sharp objects during installation to prevent housing deformation and seal damage.

Routine Maintenance Procedures

1. Regularly check the operation and fault indicators. Immediately turn off the power and troubleshoot if the fault indicator illuminates.

2. Clean the pre-filter and collector plates every 1-3 months (adjust based on pollution levels). Turn off the power before removal, rinse with water or neutral detergent, and air dry completely before reinstallation.

3. Periodically inspect power lines and insulators for damage or aging to prevent electric leakage and short circuits.

4. Avoid touching the high-voltage electrostatic unit during maintenance. After reassembly, conduct a test run to confirm normal operation.
