	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Free Air Delivery:		Free air delivery (FAD) is the actual air produced by the compressor pump at the rated pressure.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Vacuum Specifications

	Ultimate Vacuum / Pressure:		Vacuum or pressure is often measured in torr, or mm Hg referenced above absolute zero pressure. Sometimes the following reference terms are used: 1 torr and above: Rough Vacuum 0.001 to 1.0 torr: Medium Vacuum Below 0.001 torr: High Vacuum There are other terms and standards used, such as medium vacuum and ultra high vacuum; consult supplier for application specifications.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Pumping Speed / Displacement:		Pumping speed or displacements relates to the air volume capacity of the vacuum pump. Vacuum pumps are flow-rated according to the volume of air exhausted with no pressure differential across the pump.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Power Source

	Power Source
	Your choices are...
	None		Not having a power source is an option for some high vacuum pumps such as turbomolecular, where vacuum is increased by molecular absorption rather than mechanically moving parts.
	Compressed Air / Fluid		In compressed air / fluid systems, power is derived from nonelectric media such as motive fluid. Compressed air is most common, but hydraulic or other power sources are possible.
	DC Power		DC power includes battery and power supply inputs.
	AC Single Phase		Single-phase AC motor voltages include 115V/60Hz and 230V/50Hz.
	AC Three Phase		Many industrial devices run from three phase power such as 208V or 377V.
	Engine		Pumps whose primary power comes from an engine, such as a gasoline or diesel engine.
	Other		Other unlisted or specialized power source.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Motor Power:		Motor power is a reference value used to characterize vacuum pump size.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Vacuum Pump Stages

	Vacuum Pump Stages		Stages can be sequential stages of the same technology type (mechanical or Venturi), or two or more different type pumps packaged together, such as a rough, medium, and high vacuum pump system of different technologies.
	Your choices are...
	Single Stage		In single stage of evacuation, air is moved directly from chamber into atmosphere.
	Two Stage		Air is evacuated in two stages for lower absolute pressure.
	Three Stage		Three chambers are used in succession.
	Four or More Stages		Four or more evacuation stages are employed.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Lubrication Style

	Lubrication Style
	Your choices are...
	Dry / Oil-less		Dry or oil-less lubrication styles use permanently sealed bearings or other isolation technology eliminate oil in the fluid train.
	Splash Lubrication		Oil splashes onto components from bath.
	Oil-flooded		Oil-flooded lubrication is sometimes used in rotary vane and other mechanical pump styles. This type of lubrication involves a heavy application of oil for moving parts.
	Positive Pressure		In positive pressure lubrication, oil pressure is maintained for highest level of lubrication.
	Other		Other unlisted or specialized lubrication technique.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Mounting

	Your choices are...
	Benchtop		Benchtop mounting is used for products small enough to mount or be placed on a bench or table. These models may include portability.
	Cart / Portable		Portable mounts include wheels, casters, or easily movable frames for frequent relocation.
	Floor / Skid		The device rests on floor or on a skid; they are typically used for larger vacuum pumps.
	Permanent Installation		Permanent installation is used with very large systems or stations that are installed permanently in one place.
	Other		Other unlisted, specialized, or proprietary mounting style.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
