The Ariel A-21237 is an aluminum manifold designed to accommodate two force-feed lubricator pumps and an auto relief valve. This component is integral to Ariel's enhanced force-feed lubrication system, which ensures precise and reliable delivery of lubricant to critical compressor parts, thereby enhancing performance and extending equipment lifespan. The manifold's design facilitates efficient distribution of lubricant, contributing to the overall effectiveness of the lubrication system.
