The VR1000 vacuum regulator is used on all AirSep systems except the new CCE ÂirSep systems, and regulates the maximum vacuum the engine crankcase will experience if the main air filter element is dirty or fouled with exhaust soot.
It replaced the older vacuum limiter in 1994. Upgrade kits are available.
