An oil-free vacuum pump is a mechanical vacuum pump that operates without the need for any oil lubrication. It features a simple structure, easy operation, convenient maintenance, and is environmentally friendly with no risk of contamination.
High exhaust capacity makes it especially advantageous for applications involving large filtration volumes, high-viscosity media, and particle-rich substances.
The vacuum diaphragm is integrally formed from PTFE (polytetrafluoroethylene) with a substantial thickness, allowing for long-term continuous use.
The housing and components are all corrosion-resistant treated, enabling reliable operation under corrosive and organic gas conditions.
Simple structural design with a compact and attractive casing, featuring low noise and low vibration.
Multiple vacuum level options to better meet your needs.
Environmental
LabTech oil-free vacuum pumps are ideal for applications requiring contamination-free vacuum generation in environmental laboratories. Their robust design and corrosion-resistant components ensure reliable performance when handling corrosive or particulate-laden gases in air, water, and soil sample analyses.
Typical Applications and Compatible Methods: EPA Method 8260 — Volatile Organic Compounds (VOCs) analysis requiring clean vacuum for sample preparation
EPA Method 624 — Purge and Trap for volatile organic analysis in water and soil matrices
ISO 14001 — Environmental management systems supporting analytical processes with oil-free vacuum solutions
ASTM D3686 — Standard Test Method for Vapor Pressure of Petroleum Products and Liquid Fuels using oil-free vacuum pumps
