Penray has released a line of heavy-duty coolant filters which feature new synthetic media technology.

The filters use Penray’s fiberglass-based filtering media incorporated into a triple-layer design that is made to perform exceptionally, even under extreme conditions, according to the company. The triple-layer design is built on a structural steel screen with an epoxy coating to provide a durable foundation for the filter.

Many of the filters also incorporate Penray’s Need-Release technology, which releases coolant additives and fortifiers as needed to stabilize the coolant. The Need-Release filters have a membrane that senses when the coolant chemistry is deteriorating and releases one of four charges of additives and fortifiers to fix the instability.

Penray’s new filters are designed to last up to 150,000 miles, 15 months, or 3,000 operating hours.

They are compatible with all conventional coolants as well as Penray’s Extended Life Coolants. Filters are available for all popular Class 6, 7 and 8 vehicles.
