FG Wilson high efficiency filters are strong enough to withstand the toughest operating conditions. The cellulose / glass filter media protects the engine by trapping and retaining contaminants, thus preventing damage to essential engine parts. The perforated central tube not only constitutes an internal support and reinforcement element, but also allows a maximum oil flow rate.
A steel helical spring maintains a constant load pressure on the seal and the cartridge, thus protecting the engine even in the event of pressure surges. A bypass valve protects the engine during cold starts and in very unfavourable conditions by guaranteeing the distribution of the lubricant to the vital parts of the engine. A self-draining drain valve keeps the oil in the filter, avoiding destructive dry starts for the engine.
