How Germicidal UVC Technology Works

Germicidal ultraviolet light is widely used in air and water treatment applications. UVC radiation damages the DNA and RNA of microorganisms, interfering with their ability to reproduce and helping reduce microbial contamination.

When installed in a compatible UV treatment system, the Ultra Dynamics 401H-12 replacement lamp provides ultraviolet radiation for the intended treatment process. Disinfection effectiveness depends on UV intensity, exposure duration, system design, and operating conditions.

Applications

Compatible Systems and Model References

The Ultra Dynamics 401H-12 is referenced in replacement lamp listings associated with select UV air purification equipment. The following model numbers identify related systems that use germicidal UVC lamp configurations.

Dual-Lamp UV Air Purification Systems

• RM2-12/5 – Bioforce Defender Dual Lamp UVC/UVV
• FM2-12/5 – Clear Air Defender Dual Lamp UVC/UVV
• TFH-12/5 – Dual Lamp Replacement Set Reference

Important: These dual-lamp systems use separate germicidal UVC and ozone-producing UVV lamps. The Ultra Dynamics 401H-12 is a single germicidal UVC lamp and does not replace the complete dual-lamp assembly. Individual lamp compatibility must be verified before ordering.

Additional Bioforce Defender and Clear Air Defender Models

The following triple-lamp systems are also associated with the Defender UV air purification product family:

• FM3-12/12/5 – Clear Air Defender Triple Lamp UVC/UVV
• FM3-16/16/5 – Bioforce Defender Triple Lamp UVC/UVV

Note: These triple-lamp models require different lamp configurations and are included for equipment identification purposes only. They are not confirmed as directly compatible with the Ultra Dynamics 401H-12 replacement lamp.

Choosing the Correct Replacement UVC Lamp

Before ordering, verify the model number of your existing lamp and confirm that its length, electrical rating, base configuration, and lamp design match the requirements of your UV treatment system.

For dual-lamp and triple-lamp UV air purification equipment, identify each required lamp separately to ensure the correct germicidal UVC and ozone-producing UVV components are selected.
