Oil Vapor Removal Filter is designed as the final stage of filtration for the medical air stream. It is constructed from high quality aluminum, zinc and steel. The interior and exterior of each filter housing are chromated and epoxy powder coated for added durability and corrosion resistance. It uses a two-stage filtration design that maximizes efficiency and extends the life of the element. The filter does not require a differential pressure indicator, as only vapors are adsorbed by the element.

An oil well cable is used for oil wells and other hostile environments. It includes one or more solid or stranded conductive elements, which is covered by an insulating layer of high-temperature insulation. The insulating layer is covered by a metallic barrier composed of tape or film which may be coated with bonding material.
