Simple yet powerful, the GVS40A uses displacement and horsepower to achieve CFM. Unlike many other types of pumps that require complex fore traps, cryotraps, etc. – a well maintained single stage rotary vane can withstand great amounts abuse; making them very affordable and usable without much worry.
