This filter is cut to size for use on OEM UV lamp models: I223B (with K523 modular blower) or I233B (with K533 modular blower). The filter is installed on the outside of the lamp blower cover to help prevent external contaminates from entering the UV lamp. It is a direct replacement for the OEM filter.

Benefits and Features:

This is a 2 ply polyester filter that is chemically bonded together with a moisture resistant and fire retardant bonding agent. The outer layer acts as a pre-filter which allows for high efficiency and extremely low air flow resistance with no oils or adhesives needed. Miltec’s high efficient air filter will ensure clean air is delivered to the system, and hence, significantly reduce the user’s cost of consumable parts and equipment maintenance.
