Cole-Parmer Miniature Air Venturi Vacuum Pump - 0.5 CFM, 27.1" Hg - Compact Lab Vacuum for Chemistry, Medical & Industrial Applications

Designed with innovation and efficiency in mind, our air-powered Venturi pumps require no electrical power source or lubricant. Their revolutionary design takes advantage of the venturi effect, where compressed air passing through a constricted orifice creates a pressure drop that draws air through a vacuum port. This results in a clean and efficient vacuum (up to 27.1" Hg) without the need for oil or electricity. With no moving parts or electrical hazards, our air-powered pumps offer an intrinsically safe solution for your vacuum needs. Their remarkably compact size allows you to design vacuum systems with smaller, less expensive components, reducing both initial costs and long-term maintenance expenses. We've also included a replaceable silencer in each model (except 79165-40) to reduce noise levels by up to 30% while offering minimal resistance to air flow. Select the vacuum pump that best suits your specific application. We even offer a model (78165-20) with a built-in vacuum gauge for easy visual monitoring, which proves helpful during troubleshooting. To ensure optimum performance and longevity, we recommend placing an air filter upstream of the pump. This filter should have a pore size of 50 µm or smaller, effectively prolonging the service life of your vacuum pump. Whether you're a scientist, engineer, or manufacturer, our Cole-Parmer Venturi Vacuum Pump is your go-to solution for clean and efficient vacuum operations.

AIR-POWERED PERFORMANCE - These air vacuum pumps take advantage of the venturi effect—as a stream of compressed air exits a constricted orifice the resulting pressure drop draws air through a vacuum port. No moving parts means this air vacuum pump boasts an extended lifespan and low maintenance requirements.

CLEAN & EFFICIENT - Since they require no oil or electricity, the resulting vacuum (up to 27.1" Hg) is clean and efficient. With no moving parts or electrical hazards, these lab vacuum pumps are also intrinsically safe.

FAST RESPONSE, MINIMAL LOSS - The compact size of this venturi vacuum generator allows for placement close to applications, ensuring quick responses and minimal vacuum loss.

COST-EFFECTIVE OPERATION - The remarkably compact size of these venturi pumps enables you to design vacuum systems with smaller, less expensive components and reduced maintenance costs

INCLUDES Each model (except 79165-40) includes a replaceable silencer that reduces noise levels up to 30% while offering minimal resistance to air flow.
