Whatman® Vacu-Guard™ 150 Vacuum Protection Filters

Protect Your Pump, Eliminate Health Hazards

Inline capsule devices remove organic vapors to protect vacuum pumps and minimize harmful pump exhaust fumes. Choose from three filter types: carbon, for removing organic vapors and radioactive particles; color-changing desiccant, for high velocity acidic air streams; or molecular sieve, for organic and alkaline air streams.
Specifications: Vacu-Guard 150 Filters are rated for particle retention in air Ž 0.1µm 99.99%. Solvent solutions with low surface tension will pass through. Use with stepped barb connection for 10–12mm inside dia. hose. Can be installed on pump inlet. Useful as a backup between cold trap and pump for protection from vapors if cold trap fails.
