Key Features

• 100% Oil-Free Performance: Eliminates the need for routine oil top-ups and oil filter changes, preventing toxic hydrocarbon emissions and ensuring a safe, clean-air testing environment.

• Accurate Suction Control: Outfitted with an easy-to-read front-mounted vacuum gauge and an adjustable control knob, allowing operators to regulate and hold precise negative pressure limits.

• Smart Overload Protection: Built with an automated internal thermal switch that turns off the motor instantly if overheating occurs, protecting the diaphragm and internal bearings from damage.

• Compact and Portable Profile: Engineered with a lightweight aluminum body and an integrated top handle, making it highly portable and space-saving on busy laboratory workbenches.

• Anti-Vibration Footing: Outfitted with heavy-duty, high-elasticity rubber suction feet that anchor the pump firmly to the desk, absorbing mechanical vibrations and dampening operational sound.

Primary Applications

• Standard Laboratory Filtration: Supplying smooth, continuous negative pressure for vacuum filtering flasks, Buchner funnel units, and microbiology test manifolds.

• Rotary Evaporators & Desiccators: Maintaing constant, stable vacuum levels for small-scale solvent evaporations and protecting moisture-sensitive materials inside storage jars.

• Clinical and Dental Aspiration: Providing clean, dependable medical-grade suction for fluid extraction, surgical aspirators, and biological waste transfers.

• Air Sampling & Gas Analysis: Driving localized air monitoring systems, environmental dust collectors, and gas chromatographic intake lines where pure, unpolluted airflow is required.
