PRODUCT CATALOG
MAXMAC Negative Ion Generator Modules include compact, automotive-grade, and air purifier-dedicated modules, as well as high-voltage packs designed for integration with customer control boards. Powered by mature high-voltage corona discharge technology, these low-power, low-ozone modules support a wide DC 9–16V input range and optional EN control, DIG diagnostic feedback, and LIN bus communication.
View Negative Ion Modules
MAXMAC plasma generator modules include plasma ion generators, bipolar ion generators, and OEM high-voltage packs designed to generate balanced positive and negative ions for advanced air purification. Engineered for flexible integration into automotive HVAC systems, air treatment units, purifiers, and custom ventilation products.
View Plasma Generator ModulesMAXMAC guides OEM customers in selecting and integrating the ideal ionization technology tailored to their specific operating environments.
Negative ion generator modules use a high-voltage conversion circuit to raise a low DC input to a high negative DC voltage. At the emitter tip, the resulting electric field produces a corona discharge that releases electrons. These electrons are rapidly captured by oxygen molecules in the surrounding air, forming negative ions that disperse into the airflow. The module can be integrated with fans, filters, sensors, and embedded control systems according to the requirements of the final air-treatment product.
A bipolar plasma generator applies high-frequency alternating voltage across specially designed electrodes to produce controlled positive and negative ions. These ions disperse into the airflow and interact with airborne particles and contaminants. Depending on the electrode configuration, ion output, airflow conditions, and system design, the technology can support active air treatment and complement the product’s filtration system.
Ions generated through corona discharge have a very short lifespan and can be neutralized easily. Effective dispersion therefore depends on carefully engineered airflow and Emitter placement. If the airflow speed is too low, ions may accumulate and neutralize around the discharge area or become absorbed by the enclosure. If the airflow is too high or excessively turbulent, the discharge may become unstable or ozone levels may exceed the intended limit.
The Emitter must therefore be positioned precisely within a high-velocity area of the main air duct, allowing the airflow to carry ions rapidly away from the discharge tip while maintaining system-level ozone control. During OEM/ODM development, MAXMAC determines the optimal installation position for the Emitter—including the discharge needle or carbon brush—according to the requirements of each project, helping ensure efficient ion release and stable transmission throughout the complete product.
CUSTOMIZABLE IONIZER PLATFORM
MAXMAC develops custom ionizer modules (custom ionizer module) around the actual control board, airflow structure, safety requirement, and production plan of the OEM product. Customers can start from an existing negative ion generator, plasma generator, or high-voltage pack, then customize the module for final equipment integration.
Most automotive and embedded ionizer applications operate on a standard DC 9–16V input, while high-voltage packs can be custom-engineered to match specific customer power architectures. Before finalizing the electrical design, MAXMAC thoroughly evaluates key parameters—including input voltage, current limits, standby power consumption, EMC compliance, and control-board compatibility—to ensure seamless system integration.
Effective air treatment requires a precise balance between ion concentration and ozone suppression. MAXMAC collaborates closely with clients to define key operational parameters—including targeted negative or bipolar ion output and airflow velocity—ensuring maximum purification performance while strictly adhering to your product’s ozone limit requirements.
For simple devices, MAXMAC can provide EN control and DIG feedback. For automotive HVAC and vehicle projects, LIN communication can be supported for module control, sleep mode, running status, fault diagnosis, and system integration.
Real-time diagnostic feedback allows the main control board to monitor module operation and immediately detect abnormal output, open circuits, short circuits, or communication status. This capability is essential for ensuring safety and long-term operating stability in demanding embedded applications.
OZONE & SAFETY
Addressing industry concerns regarding excessive ozone emission, MAXMAC establishes low-ozone design as a strict manufacturing standard across all product lines. Through precision hardware circuitry and emitter optimization, every ionizer module produced by MAXMAC strictly adheres to the ozone concentration baseline of <0.05 PPM, fully complying with national standard testing requirements to deliver a pure air experience free of secondary pollution.
IONIZER APPLICATIONS
Ionizer modules are used across OEM air treatment products where compact ion output, airflow integration, low-ozone design, and reliable control are required. MAXMAC helps customers match the right module to the final product environment.
An HVAC ion generator solution can be seamlessly integrated into air ducts, fan coil units, ventilation systems, air conditioners, and fresh-air equipment. MAXMAC conducts a comprehensive review of key operating factors—including airflow velocity, mounting clearances, power architecture, control interfaces, and ozone limits—to recommend or engineer the optimal module for your system.

Contact an EngineerAn ion generator is an embedded air treatment component that uses a high-voltage circuit and emitter to release ions into airflow. An air ionizer module is the compact OEM component used to integrate this function into air purifiers, HVAC systems, vehicle cabins, fresh-air equipment, and home appliances.
A negative ion generator mainly releases negative ions, while a bipolar plasma generator produces controlled positive and negative ions. The correct choice depends on product structure, airflow, ozone requirements, control method, target application, and the validation plan.
Negative ion generators offer compact installation, low power consumption, flexible emitter placement, and easy integration with fans, filters, sensors, and control boards. Actual air-treatment performance depends on ion output, airflow, installation position, filtration, operating conditions, and system-level validation.
An ionizer is designed to release ions into airflow, while an ozone generator intentionally produces ozone as its primary output. Ionizer modules may produce trace ozone as a by-product, so emitter structure, voltage, airflow, and ozone validation must be carefully controlled. MAXMAC develops low-ozone ionizer modules for OEM applications.
Ionizer modules may produce trace ozone depending on high-voltage design, emitter structure, airflow, material, and operating conditions. MAXMAC designs low-ozone ionizer modules and supports ozone testing. Several module specifications use ozone targets below 0.05 ppm, with some project limits reaching ≤0.01 ppm under stated conditions.
