What is a good cfm for a vacuum pump?
We know that a good vacuum has a balanced CFM and water lift rating – so what do good numbers look like? A strong air flow rating is around 125 CFM and higher. This is strong enough air flow to pick up most anything you may work with – including dust from 5″ or smaller grinders.
How do you calculate CFM for a vacuum pump?
Cubic Feet per Minute (cfm) or Cubic Meters per Hour (m3/h) are the two standard measurements. The number corresponds to the volume of the suction chamber multiplied by the pump revolutions in the time unit and by a correction coefficient which is usually 0.85.

What does 3 CFM mean?
CFM measures the volume of air, in cubic feet, for each minute it moves. In the case of an air compressor, CFM indicates how much air can move per minute. For example, an air compressor’s output rated for 30 CFM means 30 cubic feet of air is flowing per minute.
How much oil does a Robinair vacuum pump hold?
15 ounces
The pump is shipped without oil in the reservoir. Before starting the pump, fill it with oil. Remove the OIL FILL cap (plastic plug directly in front of the handle), and add oil until oil just shows in the bottom of the sight glass. The approximate oil capacity of the pump is 15 ounces.
What is the difference between a 1 stage and 2 stage vacuum pump?
The first stage generates a medium vacuum and the second stage processes the exhaust of the first stage to create a better vacuum. As a result, two stage pumps can produce a deeper vacuum than single stage pumps.
