The purpose of the Sporlan Oil Level Control is to regulate theflow of oil to the compressor crankcase to maintain a minimum oil level as specified by the compressor manufacturer for any given application. The Oil Level Control is adjustable between 1/2 sightglass and 1/4 sightglass at any pressure differential between 0.35 and 6.2 bar. As the level of oil is lowered in the compressor crankcase by being pumped out, the float of the Oil Level Control is lowered and opens a needle valve allowing oil to flow from the oil reservoir to the compressor crankcase.
