This replacement kit includes a G4T5 non-ozone UV light bulb and an FS-5 fluorescent starter, designed for Fresh Air 1.5 by EcoQuest air purification systems.
Compatible with: Fresh Air 1.5 by EcoQuest, Systems using G4T5 UV lamps and FS-5 starters
Replacing both components at the same time helps ensure reliable operation and prevents common starting problems that occur when a new UV lamp is installed with an old starter.
A UV light bulb may not start with an old starter, even if the bulb itself is brand new. Over time, starters wear out and may fail to properly ignite the lamp. Installing a new bulb together with a new starter helps restore proper system performance.
This kit provides a convenient and cost-effective solution, allowing you to replace both essential components in one purchase. Buying the bundle is typically more affordable than purchasing the parts separately and helps avoid additional maintenance later.
The non-ozone G4T5 UV bulb produces ultraviolet light without generating ozone, making it suitable for systems designed to operate with ozone-free UV lamps.
This replacement kit is commonly used during routine maintenance of Fresh Air 1.5 by EcoQuest air purification systems.
For best results, replace the UV bulb and starter at the same time.
Using latex gloves during installation is recommended to prevent oils from transferring to the lamp surface.
